-MAJOR CHANGES IN VERSION 0.9
+RELEASE NOTES - VERSION 0.10
============================
-Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into
-detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think
-it's best to get these changes out of the way now while the library is still relatively young and unknown.
+Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert
+audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies
+to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign.
-There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in
-advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for
-you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes).
+Changes to Data Conversion
+--------------------------
+The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other
+situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a
+pointer to the input data directly rather than dealing with a callback.
-Rebranding to "miniaudio"
--------------------------
-The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
+The following are the data conversion APIs that have been removed and their replacements:
-1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
-2) I don't like the look of the underscore.
+ - ma_format_converter -> ma_convert_pcm_frames_format()
+ - ma_channel_router -> ma_channel_converter
+ - ma_src -> ma_resampler
+ - ma_pcm_converter -> ma_data_converter
-This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's
-better to get this out of the road now rather than later. Also, since there are necessary API changes for full-duplex support
-I think it's better to just get the namespace change over and done with at the same time as the full-duplex changes. I'm hoping
-this will be the last of the major API changes. Fingers crossed!
+The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the
+`*_process_pcm_frames()` function as a pointer to a buffer.
-The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's
-your preference.
+The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel
+conversion is also simple which you can do with `ma_channel_converter` via `ma_channel_converter_process_pcm_frames()`.
+Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you
+call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to
+output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated.
-Full-Duplex Support
--------------------
-The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
+The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably
+makes it the best option if you need to do data conversion.
-1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted
- to avoid a third callback just for full-duplex so the decision was made to break this API and unify the callbacks. Now,
- there is just one callback which is the same for all three modes (playback, capture, duplex). The new callback looks like
- the following:
+In addition to changes to the API design, a few other changes have been made to the data conversion pipeline:
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+ - The sinc resampler has been removed. This was completely broken and never actually worked properly.
+ - The linear resampler now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with the
+ `lpfOrder` option, which has a maximum value of MA_MAX_FILTER_ORDER.
+ - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before
+ processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however
+ `ma_data_converter` will handle this for you.
- This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In
- playback-only mode, pInput will be null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer
- returned from the callback since it's not necessary for miniaudio anymore.
-2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client
- to choose a different PCM format for the playback and capture sides. The old ma_device_config object simply did not allow
- this and needed to change. With these changes you now specify the device ID, format, channels, channel map and share mode
- on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture.
+Custom Memory Allocators
+------------------------
+miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more
+flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the
+`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure.
- Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now,
- the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking
- just the context, device config and a pointer to the device object being initialized. The rationale for this change is that
- it just makes more sense to me that these are set as part of the config like everything else.
+The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by
+`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same
+way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults.
- Example device initialization:
+The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults.
+Otherwise they will use the relevant callback in the structure.
- ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture.
- config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
- config.playback.format = ma_format_f32;
- config.playback.channels = 2;
- config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device.
- config.capture.format = ma_format_s16;
- config.capture.channels = 1;
- config.sampleRate = 44100;
- config.dataCallback = data_callback;
- config.pUserData = &myUserData;
+ - ma_malloc()
+ - ma_realloc()
+ - ma_free()
+ - ma_aligned_malloc()
+ - ma_aligned_free()
+ - ma_rb_init() / ma_rb_init_ex()
+ - ma_pcm_rb_init() / ma_pcm_rb_init_ex()
- result = ma_device_init(&myContext, &config, &device);
- if (result != MA_SUCCESS) {- ... handle error ...
- }
+Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom
+allocation callbacks.
- Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has
- been renamed to "stopCallback".
-This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample
-rate conversion is required for the playback device:
- - Core Audio
- - JACK
- - AAudio
- - OpenSL
- - WebAudio
+Buffer and Period Configuration Changes
+---------------------------------------
+The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables
+`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by
+the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine
+latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called
+`periodSizeInFrames` and `periodSizeInMilliseconds`.
-In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such
-thorough testing. If you experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample
-program that reproduces the issue if possible).
+These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is
+that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to
+configure latency.
+The following unused APIs have been removed:
+ ma_get_default_buffer_size_in_milliseconds()
+ ma_get_default_buffer_size_in_frames()
+
+The following macros have been removed:
+
+ MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY
+ MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE
+
+
Other API Changes
-----------------
-In addition to the above, the following API changes have been made:
+Other less major API changes have also been made in version 0.10.
-- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
-- The onLogCallback member of ma_context_config has been renamed to "logCallback".
-- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
- - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
-- Some APIs have been renamed:
- - mal_decoder_read() -> ma_decoder_read_pcm_frames()
- - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
- - mal_sine_wave_read() -> ma_sine_wave_read_f32()
- - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
-- Some APIs have been removed:
- - mal_device_get_buffer_size_in_bytes()
- - mal_device_set_recv_callback()
- - mal_device_set_send_callback()
- - mal_src_set_input_sample_rate()
- - mal_src_set_output_sample_rate()
-- Error codes have been rearranged. If you're a binding maintainer you will need to update.
-- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection
- and to make it easier to see the priority. If you're a binding maintainer you will need to update.
-- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with
- some future planned high-level APIs.
-- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that
- the pointer comes before the count. The rationale for this is to keep it consistent with things like memcpy().
+`ma_device_set_stop_callback()` has been removed. If you require a stop callback, you must now set it via the device config just like the data callback.
+The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including
+sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes a configuration
+object called `ma_waveform_config` which defines the properties of the waveform. Use `ma_waveform_config_init()` to initialize a `ma_waveform_config` object.
+Use `ma_waveform_read_pcm_frames()` in place of `ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`.
+`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies
+the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to
+take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it more flexible, to
+prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added.
+
+`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API.
+
+
+Filters
+-------
+The following filters have been added:
+
+ |-------------|-------------------------------------------------------------------|
+ | API | Description |
+ |-------------|-------------------------------------------------------------------|
+ | ma_biquad | Biquad filter (transposed direct form 2) |
+ | ma_lpf1 | First order low-pass filter |
+ | ma_lpf2 | Second order low-pass filter |
+ | ma_lpf | High order low-pass filter (Butterworth) |
+ | ma_hpf1 | First order high-pass filter |
+ | ma_hpf2 | Second order high-pass filter |
+ | ma_hpf | High order high-pass filter (Butterworth) |
+ | ma_bpf2 | Second order band-pass filter |
+ | ma_bpf | High order band-pass filter |
+ | ma_peak2 | Second order peaking filter |
+ | ma_notch2 | Second order notching filter |
+ | ma_loshelf2 | Second order low shelf filter |
+ | ma_hishelf2 | Second order high shelf filter |
+ |-------------|-------------------------------------------------------------------|
+
+These filters all support 32-bit floating point and 16-bit signed integer formats natively. Other formats need to be converted beforehand.
+
+
+Sine, Square, Triangle and Sawtooth Waveforms
+---------------------------------------------
+Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old
+`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_config_init()` to initialize a config object, and then pass it
+into `ma_waveform_init()`. Then use `ma_waveform_read_pcm_frames()` to read PCM data.
+
+
+Noise Generation
+----------------
+A noise generation API has been added. This is used via the `ma_noise` API. Currently white, pink and Brownian noise is supported. The `ma_noise` API is
+similar to the waveform API. Use `ma_noise_config_init()` to initialize a config object, and then pass it into `ma_noise_init()` to initialize a `ma_noise`
+object. Then use `ma_noise_read_pcm_frames()` to read PCM data.
+
+
Miscellaneous Changes
---------------------
-The following miscellaneous changes have also been made.
+Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report.
-- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the
- record, this is one of the nicest audio APIs out there, just behind the BSD audio APIs).
-- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
-- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio
- was not explicitly supported. These are no longer needed and have therefore been removed.
-- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an
- exclusive mode device, or an error. The rationale for this change is to give the client more control over how to handle cases
- when the desired shared mode is unavailable.
-- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb"
- operates on PCM frames.
-- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but
- removes the attribution requirement. The rationale for this is to support countries that don't recognize public domain.
+The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on
+the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it
+was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work,
+this has been removed from all structures.
+
+Results codes have been overhauled. Unnecessary result codes have been removed, and some have been renumbered for organisation purposes. If you are are binding
+maintainer you will need to update your result codes. Support has also been added for retrieving a human readable description of a given result code via the
+`ma_result_description()` API.

-ABOUT
-=====
-miniaudio is a single file library for audio playback and capture. It's written in C (compilable as
-C++) and released into the public domain.
+Introduction
+============
+miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file:
-Supported Backends:
- - WASAPI
- - DirectSound
- - WinMM
- - Core Audio (Apple)
- - ALSA
- - PulseAudio
- - JACK
- - sndio (OpenBSD)
- - audio(4) (NetBSD and OpenBSD)
- - OSS (FreeBSD)
- - AAudio (Android 8.0+)
- - OpenSL|ES (Android only)
- - Web Audio (Emscripten)
- - Null (Silence)
+ ```c
+ #define MINIAUDIO_IMPLEMENTATION
+ #include "miniaudio.h
+ ```
-Supported Formats:
- - Unsigned 8-bit PCM
- - Signed 16-bit PCM
- - Signed 24-bit PCM (tightly packed)
- - Signed 32-bit PCM
- - IEEE 32-bit floating point PCM
+You can #include miniaudio.h in other parts of the program just like any other header.
+miniaudio uses the concept of a "device" as the abstraction for physical devices. The idea is that you choose a physical device to emit or capture audio from,
+and then move data to/from the device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a callback which you specify when
+initializing the device.
-USAGE
-=====
-miniaudio is a single-file library. To use it, do something like the following in one .c file.
- #define MINIAUDIO_IMPLEMENTATION
- #include "miniaudio.h"
+When initializing the device you first need to configure it. The device configuration allows you to specify things like the format of the data delivered via
+the callback, the size of the internal buffer and the ID of the device you want to emit or capture audio from.
-You can then #include this file in other parts of the program as you would with any other header file.
+Once you have the device configuration set up you can initialize the device. When initializing a device you need to allocate memory for the device object
+beforehand. This gives the application complete control over how the memory is allocated. In the example below we initialize a playback device on the stack,
+but you could allocate it on the heap if that suits your situation better.
-miniaudio uses an asynchronous, callback based API. You initialize a device with a configuration (sample rate,
-channel count, etc.) which includes the callback you want to use to handle data transmission to/from the
-device. In the callback you either read from a data pointer in the case of playback or write to it in the case
-of capture.
+ ```c
+ void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
+ {+ // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both pOutput and pInput will be valid and you can
+ // move data from pInput into pOutput. Never process more than frameCount frames.
+ }
-Playback Example
-----------------
- void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)
- {- ma_decoder* pDecoder = (ma_decoder*)pDevice->pUserData;
- if (pDecoder == NULL) {- return;
- }
-
- ma_decoder_read_pcm_frames(pDecoder, frameCount, pOutput);
- }
+ ...
+
+ ma_device_config config = ma_device_config_init(ma_device_type_playback);
+ config.playback.format = MY_FORMAT;
+ config.playback.channels = MY_CHANNEL_COUNT;
+ config.sampleRate = MY_SAMPLE_RATE;
+ config.dataCallback = data_callback;
+ config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData).
- ...
+ ma_device device;
+ if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {+ ... An error occurred ...
+ }
- ma_device_config config = ma_device_config_init(ma_device_type_playback);
- config.playback.format = decoder.outputFormat;
- config.playback.channels = decoder.outputChannels;
- config.sampleRate = decoder.outputSampleRate;
- config.dataCallback = data_callback;
- config.pUserData = &decoder;
+ ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually.
- ma_device device;
- if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) {- ... An error occurred ...
- }
+ ...
- ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually.
+ ma_device_uninit(&device); // This will stop the device so no need to do that manually.
+ ```
- ...
+In the example above, `data_callback()` is where audio data is written and read from the device. The idea is in playback mode you cause sound to be emitted
+from the speakers by writing audio data to the output buffer (`pOutput` in the example). In capture mode you read data from the input buffer (`pInput`) to
+extract sound captured by the microphone. The `frameCount` parameter tells you how many frames can be written to the output buffer and read from the input
+buffer. A "frame" is one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 samples: one for the left, one for the right.
+The channel count is defined by the device config. The size in bytes of an individual sample is defined by the sample format which is also specified in the
+device config. Multi-channel audio data is always interleaved, which means the samples for each frame are stored next to each other in memory. For example, in
+a stereo stream the first pair of samples will be the left and right samples for the first frame, the second pair of samples will be the left and right samples
+for the second frame, etc.
- ma_device_uninit(&device); // This will stop the device so no need to do that manually.
+The configuration of the device is defined by the `ma_device_config` structure. The config object is always initialized with `ma_device_config_init()`. It's
+important to always initialize the config with this function as it initializes it with logical defaults and ensures your program doesn't break when new members
+are added to the `ma_device_config` structure. The example above uses a fairly simple and standard device configuration. The call to `ma_device_config_init()`
+takes a single parameter, which is whether or not the device is a playback, capture, duplex or loopback device (loopback devices are not supported on all
+backends). The `config.playback.format` member sets the sample format which can be one of the following (all formats are native-endian):
+ |---------------|----------------------------------------|---------------------------|
+ | Symbol | Description | Range |
+ |---------------|----------------------------------------|---------------------------|
+ | ma_format_f32 | 32-bit floating point | [-1, 1] |
+ | ma_format_s16 | 16-bit signed integer | [-32768, 32767] |
+ | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] |
+ | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] |
+ | ma_format_u8 | 8-bit unsigned integer | [0, 255] |
+ |---------------|----------------------------------------|---------------------------|
-BUILDING
-========
-miniaudio should Just Work by adding it to your project's source tree. You do not need to download or install
-any dependencies. See below for platform-specific details.
+The `config.playback.channels` member sets the number of channels to use with the device. The channel count cannot exceed MA_MAX_CHANNELS. The
+`config.sampleRate` member sets the sample rate (which must be the same for both playback and capture in full-duplex configurations). This is usually set to
+44100 or 48000, but can be set to anything. It's recommended to keep this between 8000 and 384000, however.
-If you want to disable a specific backend, #define the appropriate MA_NO_* option before the implementation.
+Note that leaving the format, channel count and/or sample rate at their default values will result in the internal device's native configuration being used
+which is useful if you want to avoid the overhead of miniaudio's automatic data conversion.
-Note that GCC and Clang requires "-msse2", "-mavx2", etc. for SIMD optimizations.
+In addition to the sample format, channel count and sample rate, the data callback and user data pointer are also set via the config. The user data pointer is
+not passed into the callback as a parameter, but is instead set to the `pUserData` member of `ma_device` which you can access directly since all miniaudio
+structures are transparent.
+Initializing the device is done with `ma_device_init()`. This will return a result code telling you what went wrong, if anything. On success it will return
+`MA_SUCCESS`. After initialization is complete the device will be in a stopped state. To start it, use `ma_device_start()`. Uninitializing the device will stop
+it, which is what the example above does, but you can also stop the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again.
+Note that it's important to never stop or start the device from inside the callback. This will result in a deadlock. Instead you set a variable or signal an
+event indicating that the device needs to stop and handle it in a different thread. The following APIs must never be called inside the callback:

+ ma_device_stop()
-Building for macOS and iOS
---------------------------
-The macOS build should compile clean without the need to download any dependencies or link to any libraries or
-frameworks. The iOS build needs to be compiled as Objective-C (sorry) and will need to link the relevant frameworks
-but should Just Work with Xcode.
+You must never try uninitializing and reinitializing a device inside the callback. You must also never try to stop and start it from inside the callback. There
+are a few other things you shouldn't do in the callback depending on your requirements, however this isn't so much a thread-safety thing, but rather a real-
+time processing thing which is beyond the scope of this introduction.
-Building for Linux
-------------------
-The Linux build only requires linking to -ldl, -lpthread and -lm. You do not need any development packages.
+The example above demonstrates the initialization of a playback device, but it works exactly the same for capture. All you need to do is change the device type
+from `ma_device_type_playback` to `ma_device_type_capture` when setting up the config, like so:
-Building for BSD
-----------------
-The BSD build only requires linking to -ldl, -lpthread and -lm. NetBSD uses audio(4), OpenBSD uses sndio and
-FreeBSD uses OSS.
+ ```c
+ ma_device_config config = ma_device_config_init(ma_device_type_capture);
+ config.capture.format = MY_FORMAT;
+ config.capture.channels = MY_CHANNEL_COUNT;
+ ```
+
+In the data callback you just read from the input buffer (`pInput` in the example above) and leave the output buffer alone (it will be set to NULL when the
+device type is set to `ma_device_type_capture`).
-Building for Android
---------------------
-AAudio is the highest priority backend on Android. This should work out out of the box without needing any kind of
-compiler configuration. Support for AAudio starts with Android 8 which means older versions will fall back to
-OpenSL|ES which requires API level 16+.
+These are the available device types and how you should handle the buffers in the callback:
-Building for Emscripten
------------------------
-The Emscripten build emits Web Audio JavaScript directly and should Just Work without any configuration.
+ |-------------------------|--------------------------------------------------------|
+ | Device Type | Callback Behavior |
+ |-------------------------|--------------------------------------------------------|
+ | ma_device_type_playback | Write to output buffer, leave input buffer untouched. |
+ | ma_device_type_capture | Read from input buffer, leave output buffer untouched. |
+ | ma_device_type_duplex | Read from input buffer, write to output buffer. |
+ | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. |
+ |-------------------------|--------------------------------------------------------|
+You will notice in the example above that the sample format and channel count is specified separately for playback and capture. This is to support different
+data formats between the playback and capture devices in a full-duplex system. An example may be that you want to capture audio data as a monaural stream (one
+channel), but output sound to a stereo speaker system. Note that if you use different formats between playback and capture in a full-duplex configuration you
+will need to convert the data yourself. There are functions available to help you do this which will be explained later.
-NOTES
-=====
-- This library uses an asynchronous API for delivering and requesting audio data. Each device will have
- it's own worker thread which is managed by the library.
-- Sample data is always native-endian and interleaved. For example, ma_format_s16 means signed 16-bit
- integer samples, interleaved.
-- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI
- and Core Audio, however other backends such as PulseAudio may naturally support it, though not all have
- been tested.
-- The contents of the output buffer passed into the data callback will always be pre-initialized to zero
- unless the noPreZeroedOutputBuffer config variable in ma_device_config is set to true, in which case
- it'll be undefined which will require you to write something to the entire buffer.
-- By default miniaudio will automatically clip samples. This only applies when the playback sample format
- is configured as ma_format_f32. If you are doing clipping yourself, you can disable this overhead by
- setting noClip to true in the device config.
-- If ma_device_init() is called with a device that's not aligned to the 4 bytes on 32-bit or 8 bytes on
- 64-bit it will _not_ be thread-safe. The reason for this is that it depends on members of ma_device being
- correctly aligned for atomic assignments.
-- The sndio backend is currently only enabled on OpenBSD builds.
-- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
+The example above did not specify a physical device to connect to which means it will use the operating system's default device. If you have multiple physical
+devices connected and you want to use a specific one you will need to specify the device ID in the configuration, like so:
+ ```
+ config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device.
+ config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device.
+ ```
-BACKEND NUANCES
-===============
+To retrieve the device ID you will need to perform device enumeration, however this requires the use of a new concept called the "context". Conceptually
+speaking the context sits above the device. There is one context to many devices. The purpose of the context is to represent the backend at a more global level
+and to perform operations outside the scope of an individual device. Mainly it is used for performing run-time linking against backend libraries, initializing
+backends and enumerating devices. The example below shows how to enumerate devices.
-WASAPI
-------
-- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the
- device's native sample rate. To work around this, set wasapi.noAutoConvertSRC to true in the device config. This
- is due to IAudioClient3_InitializeSharedAudioStream() failing when the AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM flag is
- specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's lower quality internal resampler being used
- instead which will in turn enable the use of low-latency shared mode.
+ ```c
+ ma_context context;
+ if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) {+ // Error.
+ }
-PulseAudio
-----------
-- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
- https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling
- Alternatively, consider using a different backend such as ALSA.
+ ma_device_info* pPlaybackDeviceInfos;
+ ma_uint32 playbackDeviceCount;
+ ma_device_info* pCaptureDeviceInfos;
+ ma_uint32 captureDeviceCount;
+ if (ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, &pCaptureDeviceInfos, &captureDeviceCount) != MA_SUCCESS) {+ // Error.
+ }
-Android
+ // Loop over each device info and do something with it. Here we just print the name with their index. You may want to give the user the
+ // opportunity to choose which device they'd prefer.
+ for (ma_uint32 iDevice = 0; iDevice < playbackDeviceCount; iDevice += 1) {+ printf("%d - %s\n", iDevice, pPlaybackDeviceInfos[iDevice].name);+ }
+
+ ma_device_config config = ma_device_config_init(ma_device_type_playback);
+ config.playback.pDeviceID = &pPlaybackDeviceInfos[chosenPlaybackDeviceIndex].id;
+ config.playback.format = MY_FORMAT;
+ config.playback.channels = MY_CHANNEL_COUNT;
+ config.sampleRate = MY_SAMPLE_RATE;
+ config.dataCallback = data_callback;
+ config.pUserData = pMyCustomData;
+
+ ma_device device;
+ if (ma_device_init(&context, &config, &device) != MA_SUCCESS) {+ // Error
+ }
+
+ ...
+
+ ma_device_uninit(&device);
+ ma_context_uninit(&context);
+ ```
+
+The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. The first parameter is a pointer to a list of `ma_backend`
+values which are used to override the default backend priorities. When this is NULL, as in this example, miniaudio's default priorities are used. The second
+parameter is the number of backends listed in the array pointed to by the first parameter. The third parameter is a pointer to a `ma_context_config` object
+which can be NULL, in which case defaults are used. The context configuration is used for setting the logging callback, custom memory allocation callbacks,
+user-defined data and some backend-specific configurations.
+
+Once the context has been initialized you can enumerate devices. In the example above we use the simpler `ma_context_get_devices()`, however you can also use a
+callback for handling devices by using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer to a pointer that will,
+upon output, be set to a pointer to a buffer containing a list of `ma_device_info` structures. You also provide a pointer to an unsigned integer that will
+receive the number of items in the returned buffer. Do not free the returned buffers as their memory is managed internally by miniaudio.
+
+The `ma_device_info` structure contains an `id` member which is the ID you pass to the device config. It also contains the name of the device which is useful
+for presenting a list of devices to the user via the UI.
+
+When creating your own context you will want to pass it to `ma_device_init()` when initializing the device. Passing in NULL, like we do in the first example,
+will result in miniaudio creating the context for you, which you don't want to do since you've already created a context. Note that internally the context is
+only tracked by it's pointer which means you must not change the location of the `ma_context` object. If this is an issue, consider using `malloc()` to
+allocate memory for the context.
+
+
+
+Building
+========
+miniaudio should work cleanly out of the box without the need to download or install any dependencies. See below for platform-specific details.
+
+
+Windows
-------
-- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest:
- <uses-permission android:name="android.permission.RECORD_AUDIO" />
-- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
-- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are
- enumerated through Java). You can however perform your own device enumeration through Java and then set the ID in the
- ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
-- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in
- resampler is to take advantage of any potential device-specific optimizations the driver may implement.
+The Windows build should compile cleanly on all popular compilers without the need to configure any include paths nor link to any libraries.
-UWP
+macOS and iOS
+-------------
+The macOS build should compile cleanly without the need to download any dependencies nor link to any libraries or frameworks. The iOS build needs to be
+compiled as Objective-C (sorry) and will need to link the relevant frameworks but should Just Work with Xcode. Compiling through the command line requires
+linking to -lpthread and -lm.
+
+Linux
+-----
+The Linux build only requires linking to -ldl, -lpthread and -lm. You do not need any development packages.
+
+BSD
---
-- UWP only supports default playback and capture devices.
-- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
- <Package ...>
- ...
- <Capabilities>
- <DeviceCapability Name="microphone" />
- </Capabilities>
- </Package>
+The BSD build only requires linking to -lpthread and -lm. NetBSD uses audio(4), OpenBSD uses sndio and FreeBSD uses OSS.
-Web Audio / Emscripten
-----------------------
-- You cannot use -std=c* compiler flags, nor -ansi. This only applies to the Emscripten build.
-- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act
- as a factory for device objects.
-- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
-- Google is implementing a policy in their browsers that prevent automatic media output without first receiving some kind
- of user input. See here for details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting
- the device may fail if you try to start playback without first handling some kind of user input.

All formats are native-endian.
+
+
+
+Decoding
+========
+The `ma_decoder` API is used for reading audio files. To enable a decoder you must #include the header of the relevant backend library before the
+implementation of miniaudio. You can find copies of these in the "extras" folder in the miniaudio repository (https://github.com/dr-soft/miniaudio).
+
+The table below are the supported decoding backends:
+
+ |--------|-----------------|
+ | Type | Backend Library |
+ |--------|-----------------|
+ | WAV | dr_wav.h |
+ | FLAC | dr_flac.h |
+ | MP3 | dr_mp3.h |
+ | Vorbis | stb_vorbis.c |
+ |--------|-----------------|
+
+The code below is an example of how to enable decoding backends:
+
+ ```c
+ #include "dr_flac.h" // Enables FLAC decoding.
+ #include "dr_mp3.h" // Enables MP3 decoding.
+ #include "dr_wav.h" // Enables WAV decoding.
+
+ #define MINIAUDIO_IMPLEMENTATION
+ #include "miniaudio.h"
+ ```
+
+A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with `ma_decoder_init_memory()`, or from data delivered via callbacks
+with `ma_decoder_init()`. Here is an example for loading a decoder from a file:
+
+ ```c
+ ma_decoder decoder;
+ ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder);+ if (result != MA_SUCCESS) {+ return false; // An error occurred.
+ }
+
+ ...
+
+ ma_decoder_uninit(&decoder);
+ ```
+
+When initializing a decoder, you can optionally pass in a pointer to a ma_decoder_config object (the NULL argument in the example above) which allows you to
+configure the output format, channel count, sample rate and channel map:
+
+ ```c
+ ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000);
+ ```
+
+When passing in NULL for decoder config in `ma_decoder_init*()`, the output format will be the same as that defined by the decoding backend.
+
+Data is read from the decoder as PCM frames:
+
+ ```c
+ ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead);
+ ```
+
+You can also seek to a specific frame like so:
+
+ ```c
+ ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame);
+ if (result != MA_SUCCESS) {+ return false; // An error occurred.
+ }
+ ```
+
+When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding backend. This can be unnecessarily inefficient if the type
+is already known. In this case you can use the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs:
+
+ ```c
+ ma_decoder_init_wav()
+ ma_decoder_init_mp3()
+ ma_decoder_init_memory_wav()
+ ma_decoder_init_memory_mp3()
+ ma_decoder_init_file_wav()
+ ma_decoder_init_file_mp3()
+ etc.
+ ```
+
+The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer.
+
+
+
+Encoding
+========
+The `ma_encoding` API is used for writing audio files. To enable an encoder you must #include the header of the relevant backend library before the
+implementation of miniaudio. You can find copies of these in the "extras" folder in the miniaudio repository (https://github.com/dr-soft/miniaudio).
+
+The table below are the supported encoding backends:
+
+ |--------|-----------------|
+ | Type | Backend Library |
+ |--------|-----------------|
+ | WAV | dr_wav.h |
+ |--------|-----------------|
+
+The code below is an example of how to enable encoding backends:
+
+ ```c
+ #include "dr_wav.h" // Enables WAV decoding.
+
+ #define MINIAUDIO_IMPLEMENTATION
+ #include "miniaudio.h"
+ ```
+
+An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data delivered via callbacks with `ma_encoder_init()`. Below is an
+example for initializing an encoder to output to a file.
+
+ ```c
+ ma_encoder_config config = ma_encoder_config_init(ma_resource_format_wav, FORMAT, CHANNELS, SAMPLE_RATE);
+ ma_encoder encoder;
+ ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder);+ if (result != MA_SUCCESS) {+ // Error
+ }
+
+ ...
+
+ ma_encoder_uninit(&encoder);
+ ```
+
+When initializing an encoder you must specify a config which is initialized with `ma_encoder_config_init()`. Here you must specify the file type, the output
+sample format, output channel count and output sample rate. The following file types are supported:
+
+ |------------------------|-------------|
+ | Enum | Description |
+ |------------------------|-------------|
+ | ma_resource_format_wav | WAV |
+ |------------------------|-------------|
+
+If the format, channel count or sample rate is not supported by the output file type an error will be returned. The encoder will not perform data conversion so
+you will need to convert it before outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the example below:
+
+ ```c
+ framesWritten = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite);
+ ```
+
+Encoders must be uninitialized with `ma_encoder_uninit()`.
+
+
+
+Sample Format Conversion
+========================
+Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and `ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()`
+to convert between two specific formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use `ma_convert_pcm_frames_format()` to convert
+PCM frames where you want to specify the frame count and channel count as a variable instead of the total sample count.
+
+Dithering
+---------
+Dithering can be set using the ditherMode parameter.
+
+The different dithering modes include the following, in order of efficiency:
+
+ |-----------|--------------------------|
+ | Type | Enum Token |
+ |-----------|--------------------------|
+ | None | ma_dither_mode_none |
+ | Rectangle | ma_dither_mode_rectangle |
+ | Triangle | ma_dither_mode_triangle |
+ |-----------|--------------------------|
+
+Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be ignored for conversions where dithering is not needed.
+Dithering is available for the following conversions:
+
+ s16 -> u8
+ s24 -> u8
+ s32 -> u8
+ f32 -> u8
+ s24 -> s16
+ s32 -> s16
+ f32 -> s16
+
+Note that it is not an error to pass something other than ma_dither_mode_none for conversions where dither is not used. It will just be ignored.
+
+
+
+Channel Conversion
+==================
+Channel conversion is used for channel rearrangement and conversion from one channel count to another. The `ma_channel_converter` API is used for channel
+conversion. Below is an example of initializing a simple channel converter which converts from mono to stereo.
+
+ ```c
+ ma_channel_converter_config config = ma_channel_converter_config_init(ma_format, 1, NULL, 2, NULL, ma_channel_mix_mode_default, NULL);
+ result = ma_channel_converter_init(&config, &converter);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+ ```
+
+To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so:
+
+ ```c
+ ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+ ```
+
+It is up to the caller to ensure the output buffer is large enough to accomodate the new PCM frames.
+
+The only formats supported are `ma_format_s16` and `ma_format_f32`. If you need another format you need to convert your data manually which you can do with
+`ma_pcm_convert()`, etc.
+
+Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported.
+
+
+Channel Mapping
+---------------
+In addition to converting from one channel count to another, like the example above, The channel converter can also be used to rearrange channels. When
+initializing the channel converter, you can optionally pass in channel maps for both the input and output frames. If the channel counts are the same, and each
+channel map contains the same channel positions with the exception that they're in a different order, a simple shuffling of the channels will be performed. If,
+however, there is not a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed based on a mixing mode which is
+specified when initializing the `ma_channel_converter_config` object.
+
+When converting from mono to multi-channel, the mono channel is simply copied to each output channel. When going the other way around, the audio of each output
+channel is simply averaged and copied to the mono channel.
+
+In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess channels and silence extra channels. For example, converting
+from 4 to 2 channels, the 3rd and 4th channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and 4th channels.
+
+The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a simple distribution between input and output. Imagine sitting
+in the middle of a room, with speakers on the walls representing channel positions. The MA_CHANNEL_FRONT_LEFT position can be thought of as being in the corner
+of the front and left walls.
+
+Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined weights. Custom weights can be passed in as the last parameter of
+`ma_channel_converter_config_init()`.
+
+Predefined channel maps can be retrieved with `ma_get_standard_channel_map()`. This takes a `ma_standard_channel_map` enum as it's first parameter, which can
+be one of the following:

+
+Resampling
+==========
+Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something like the following:
+
+ ```c
+ ma_resampler_config config = ma_resampler_config_init(ma_format_s16, channels, sampleRateIn, sampleRateOut, ma_resample_algorithm_linear);
+ ma_resampler resampler;
+ ma_result result = ma_resampler_init(&config, &resampler);
+ if (result != MA_SUCCESS) {+ // An error occurred...
+ }
+ ```
+
+Do the following to uninitialize the resampler:
+
+ ```c
+ ma_resampler_uninit(&resampler);
+ ```
+
+The following example shows how data can be processed
+
+ ```c
+ ma_uint64 frameCountIn = 1000;
+ ma_uint64 frameCountOut = 2000;
+ ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+ if (result != MA_SUCCESS) {+ // An error occurred...
+ }
+
+ // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number of output frames written.
+ ```
+
+To initialize the resampler you first need to set up a config (`ma_resampler_config`) with `ma_resampler_config_init()`. You need to specify the sample format
+you want to use, the number of channels, the input and output sample rate, and the algorithm.
+
+The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format you will need to perform pre- and post-conversions yourself
+where necessary. Note that the format is the same for both input and output. The format cannot be changed after initialization.
+
+The resampler supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+The sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the
+only configuration property that can be changed after initialization.
+
+The miniaudio resampler supports multiple algorithms:
+
+ |-----------|------------------------------|
+ | Algorithm | Enum Token |
+ |-----------|------------------------------|
+ | Linear | ma_resample_algorithm_linear |
+ | Speex | ma_resample_algorithm_speex |
+ |-----------|------------------------------|
+
+Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider
+it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in
+the Speex Resampler section below.
+
+The algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number of
+input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+The sample rate can be changed dynamically on the fly. You can change this with explicit sample rates with `ma_resampler_set_rate()` and also with a decimal
+ratio with `ma_resampler_set_rate_ratio()`. The ratio is in/out.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_resampler_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the resampler introduces some latency. This can be retrieved in terms of both the input rate and the output rate
+with `ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`.
+
+
+Resampling Algorithms
+---------------------
+The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency,
+but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap allocations internally
+for memory management.
+
+
+Linear Resampling
+-----------------
+The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, some control over the quality of the linear resampler which
+may make it a suitable option depending on your requirements.
+
+The linear resampler performs low-pass filtering before or after downsampling or upsampling, depending on the sample rates you're converting between. When
+decreasing the sample rate, the low-pass filter will be applied before downsampling. When increasing the rate it will be performed after upsampling. By default
+a fourth order low-pass filter will be applied. This can be configured via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering.
+
+The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of the input and output sample rates (Nyquist Frequency). This
+can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make
+sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc.
+Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance
+and is a purely perceptual configuration.
+
+The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`.
+
+
+Speex Resampling
+----------------
+The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public
+domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's
+source files. To opt-in, you must first #include the following file before the implementation of miniaudio.h:
+
+ #include "extras/speex_resampler/ma_speex_resampler.h"
+
+Both the header and implementation is contained within the same file. The implementation can be included in your program like so:
+
+ #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION
+ #include "extras/speex_resampler/ma_speex_resampler.h"
+
+Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are
+initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`.
+
+The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being
+the fastest with the poorest quality and 10 being the slowest with the highest quality. The default value is 3.
+
+
+
+General Data Conversion
+=======================
+The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and resampling into one operation. This is what miniaudio uses
+internally to convert between the format requested when the device was initialized and the format of the backend's native device. The API for general data
+conversion is very similar to the resampling API. Create a `ma_data_converter` object like this:
+
+ ```c
+ ma_data_converter_config config = ma_data_converter_config_init(inputFormat, outputFormat, inputChannels, outputChannels, inputSampleRate, outputSampleRate);
+ ma_data_converter converter;
+ ma_result result = ma_data_converter_init(&config, &converter);
+ if (result != MA_SUCCESS) {+ // An error occurred...
+ }
+ ```
+
+In the example above we use `ma_data_converter_config_init()` to initialize the config, however there's many more properties that can be configured, such as
+channel maps and resampling quality. Something like the following may be more suitable depending on your requirements:
+
+ ```c
+ ma_data_converter_config config = ma_data_converter_config_init_default();
+ config.formatIn = inputFormat;
+ config.formatOut = outputFormat;
+ config.channelsIn = inputChannels;
+ config.channelsOut = outputChannels;
+ config.sampleRateIn = inputSampleRate;
+ config.sampleRateOut = outputSampleRate;
+ ma_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn);
+ config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER;
+ ```
+
+Do the following to uninitialize the data converter:
+
+ ```c
+ ma_data_converter_uninit(&converter);
+ ```
+
+The following example shows how data can be processed
+
+ ```c
+ ma_uint64 frameCountIn = 1000;
+ ma_uint64 frameCountOut = 2000;
+ ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut);
+ if (result != MA_SUCCESS) {+ // An error occurred...
+ }
+
+ // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number of output frames written.
+ ```
+
+The data converter supports multiple channels and is always interleaved (both input and output). The channel count cannot be changed after initialization.
+
+Sample rates can be anything other than zero, and are always specified in hertz. They should be set to something like 44100, etc. The sample rate is the only
+configuration property that can be changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of `ma_data_converter_config` is
+set to MA_TRUE. To change the sample rate, use `ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. The resampling
+algorithm cannot be changed after initialization.
+
+Processing always happens on a per PCM frame basis and always assumes interleaved input and output. De-interleaved processing is not supported. To process
+frames, use `ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames you can fit in the output buffer and the number
+of input frames contained in the input buffer. On output these variables contain the number of output frames that were written to the output buffer and the
+number of input frames that were consumed in the process. You can pass in NULL for the input buffer in which case it will be treated as an infinitely large
+buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated as seek.
+
+Sometimes it's useful to know exactly how many input frames will be required to output a specific number of frames. You can calculate this with
+`ma_data_converter_get_required_input_frame_count()`. Likewise, it's sometimes useful to know exactly how many frames would be output given a certain number of
+input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`.
+
+Due to the nature of how resampling works, the data converter introduces some latency if resampling is required. This can be retrieved in terms of both the
+input rate and the output rate with `ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`.
+
+
+
+Filtering
+=========
+
+Biquad Filtering
+----------------
+Biquad filtering is achieved with the `ma_biquad` API. Example:
+
+ ```c
+ ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2);
+ ma_result result = ma_biquad_init(&config, &biquad);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+
+ ...
+
+ ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount);
+ ```
+
+Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, b1 and b2, and the denominator coefficients are a0, a1 and
+a2. The a0 coefficient is required and coefficients must not be pre-normalized.
+
+Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. When using
+`ma_format_s16` the biquad filter will use fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used.
+
+Input and output frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+ ```c
+ ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount);
+ ```
+
+If you need to change the values of the coefficients, but maintain the values in the registers you can do so with `ma_biquad_reinit()`. This is useful if you
+need to change the properties of the filter while keeping the values of registers valid to avoid glitching. Do not use `ma_biquad_init()` for this as it will
+do a full initialization which involves clearing the registers to 0. Note that changing the format or channel count after initialization is invalid and will
+result in an error.
+
+
+Low-Pass Filtering
+------------------
+Low-pass filtering is achieved with the following APIs:
+
+ |---------|------------------------------------------|
+ | API | Description |
+ |---------|------------------------------------------|
+ | ma_lpf1 | First order low-pass filter |
+ | ma_lpf2 | Second order low-pass filter |
+ | ma_lpf | High order low-pass filter (Butterworth) |
+ |---------|------------------------------------------|
+
+Low-pass filter example:
+
+ ```c
+ ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order);
+ ma_result result = ma_lpf_init(&config, &lpf);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+
+ ...
+
+ ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount);
+ ```
+
+Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format you need to convert it yourself beforehand. Input and output
+frames are always interleaved.
+
+Filtering can be applied in-place by passing in the same pointer for both the input and output buffers, like so:
+
+ ```c
+ ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount);
+ ```
+
+The maximum filter order is limited to MA_MAX_FILTER_ORDER which is set to 8. If you need more, you can chain first and second order filters together.
+
+ ```c
+ for (iFilter = 0; iFilter < filterCount; iFilter += 1) {+ ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount);
+ }
+ ```
+
+If you need to change the configuration of the filter, but need to maintain the state of internal registers you can do so with `ma_lpf_reinit()`. This may be
+useful if you need to change the sample rate and/or cutoff frequency dynamically while maintaing smooth transitions. Note that changing the format or channel
+count after initialization is invalid and will result in an error.
+
+The `ma_lpf` object supports a configurable order, but if you only need a first order filter you may want to consider using `ma_lpf1`. Likewise, if you only
+need a second order filter you can use `ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient.
+
+If an even filter order is specified, a series of second order filters will be processed in a chain. If an odd filter order is specified, a first order filter
+will be applied, followed by a series of second order filters in a chain.
+
+
+High-Pass Filtering
+-------------------
+High-pass filtering is achieved with the following APIs:
+
+ |---------|-------------------------------------------|
+ | API | Description |
+ |---------|-------------------------------------------|
+ | ma_hpf1 | First order high-pass filter |
+ | ma_hpf2 | Second order high-pass filter |
+ | ma_hpf | High order high-pass filter (Butterworth) |
+ |---------|-------------------------------------------|
+
+High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, `ma_hpf2` and `ma_hpf`. See example code for low-pass filters
+for example usage.
+
+
+Band-Pass Filtering
+-------------------
+Band-pass filtering is achieved with the following APIs:
+
+ |---------|-------------------------------|
+ | API | Description |
+ |---------|-------------------------------|
+ | ma_bpf2 | Second order band-pass filter |
+ | ma_bpf | High order band-pass filter |
+ |---------|-------------------------------|
+
+Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and `ma_hpf`. See example code for low-pass filters for example
+usage. Note that the order for band-pass filters must be an even number which means there is no first order band-pass filter, unlike low-pass and high-pass
+filters.
+
+
+Notch Filtering
+---------------
+Notch filtering is achieved with the following APIs:
+
+ |-----------|------------------------------------------|
+ | API | Description |
+ |-----------|------------------------------------------|
+ | ma_notch2 | Second order notching filter |
+ |-----------|------------------------------------------|
+
+
+Peaking EQ Filtering
+--------------------
+Peaking filtering is achieved with the following APIs:
+
+ |----------|------------------------------------------|
+ | API | Description |
+ |----------|------------------------------------------|
+ | ma_peak2 | Second order peaking filter |
+ |----------|------------------------------------------|
+
+
+Low Shelf Filtering
+-------------------
+Low shelf filtering is achieved with the following APIs:
+
+ |-------------|------------------------------------------|
+ | API | Description |
+ |-------------|------------------------------------------|
+ | ma_loshelf2 | Second order low shelf filter |
+ |-------------|------------------------------------------|
+
+Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to just turn them down rather than eliminate them entirely.
+
+
+High Shelf Filtering
+--------------------
+High shelf filtering is achieved with the following APIs:
+
+ |-------------|------------------------------------------|
+ | API | Description |
+ |-------------|------------------------------------------|
+ | ma_hishelf2 | Second order high shelf filter |
+ |-------------|------------------------------------------|
+
+The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` instead of `ma_loshelf`. Where a low shelf filter is used to
+adjust the volume of low frequencies, the high shelf filter does the same thing for high frequencies.
+
+
+
+
+Waveform and Noise Generation
+=============================
+
+Waveforms
+---------
+miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example:
+
+ ```c
+ ma_waveform_config config = ma_waveform_config_init(FORMAT, CHANNELS, SAMPLE_RATE, ma_waveform_type_sine, amplitude, frequency);
+
+ ma_waveform waveform;
+ ma_result result = ma_waveform_init(&config, &waveform);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+
+ ...
+
+ ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount);
+ ```
+
+The amplitude, frequency and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()` and
+`ma_waveform_set_sample_rate()` respectively.
+
+You can reverse the waveform by setting the amplitude to a negative value. You can use this to control whether or not a sawtooth has a positive or negative
+ramp, for example.
+
+Below are the supported waveform types:
+
+ |---------------------------|
+ | Enum Name |
+ |---------------------------|
+ | ma_waveform_type_sine |
+ | ma_waveform_type_square |
+ | ma_waveform_type_triangle |
+ | ma_waveform_type_sawtooth |
+ |---------------------------|
+
+
+
+Noise
+-----
+miniaudio supports generation of white, pink and brownian noise via the `ma_noise` API. Example:
+
+ ```c
+ ma_noise_config config = ma_noise_config_init(FORMAT, CHANNELS, ma_noise_type_white, SEED, amplitude);
+
+ ma_noise noise;
+ ma_result result = ma_noise_init(&config, &noise);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+
+ ...
+
+ ma_noise_read_pcm_frames(&noise, pOutput, frameCount);
+ ```
+
+The noise API uses simple LCG random number generation. It supports a custom seed which is useful for things like automated testing requiring reproducibility.
+Setting the seed to zero will default to MA_DEFAULT_LCG_SEED.
+
+By default, the noise API will use different values for different channels. So, for example, the left side in a stereo stream will be different to the right
+side. To instead have each channel use the same random value, set the `duplicateChannels` member of the noise config to true, like so:
+
+ ```c
+ config.duplicateChannels = MA_TRUE;
+ ```
+
+Below are the supported noise types.
+
+ |------------------------|
+ | Enum Name |
+ |------------------------|
+ | ma_noise_type_white |
+ | ma_noise_type_pink |
+ | ma_noise_type_brownian |
+ |------------------------|
+
+
+
+Ring Buffers
+============
+miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates
+on bytes, whereas the `ma_pcm_rb` operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around `ma_rb`.
+
+Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved streams. The caller can also allocate their own backing memory for
+the ring buffer to use internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for you.
+
+The examples below use the PCM frame variant of the ring buffer since that's most likely the one you will want to use. To initialize a ring buffer, do
+something like the following:
+
+ ```c
+ ma_pcm_rb rb;
+ ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb);
+ if (result != MA_SUCCESS) {+ // Error
+ }
+ ```
+
+The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because it's the PCM varient of the ring buffer API. For the regular
+ring buffer that operates on bytes you would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes instead of frames. The
+fourth parameter is an optional pre-allocated buffer and the fifth parameter is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation
+routines. Passing in NULL for this results in MA_MALLOC() and MA_FREE() being used.
+
+Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is offset from each other based on the stride. To manage your sub-
+buffers you can use `ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and `ma_pcm_rb_get_subbuffer_ptr()`.
+
+Use 'ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section of the ring buffer. You specify the number of frames you
+need, and on output it will set to what was actually acquired. If the read or write pointer is positioned such that the number of frames requested will require
+a loop, it will be clamped to the end of the buffer. Therefore, the number of frames you're given may be less than the number you requested.
+
+After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the buffer and then "commit" it with `ma_pcm_rb_commit_read()` or
+`ma_pcm_rb_commit_write()`. This is where the read/write pointers are updated. When you commit you need to pass in the buffer that was returned by the earlier
+call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and
+`ma_pcm_rb_commit_write()` is what's used to increment the pointers.
+
+If you want to correct for drift between the write pointer and the read pointer you can use a combination of `ma_pcm_rb_pointer_distance()`,
+`ma_pcm_rb_seek_read()` and `ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only move the read pointer forward via
+the consumer thread, and the write pointer forward by the producer thread. If there is too much space between the pointers, move the read pointer forward. If
+there is too little space between the pointers, move the write pointer forward.
+
+You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` API. This is exactly the sample, only you will use the `ma_rb`
+functions instead of `ma_pcm_rb` and instead of frame counts you'll pass around byte counts.
+
+The maximum size of the buffer in bytes is 0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1) due to the most significant bit being used to encode a flag and the internally
+managed buffers always being aligned to MA_SIMD_ALIGNMENT.
+
+Note that the ring buffer is only thread safe when used by a single consumer thread and single producer thread.
+
+
+
+Backends
+========
+The following backends are supported by miniaudio.
+
+ |-------------|-----------------------|--------------------------------------------------------|
+ | Name | Enum Name | Supported Operating Systems |
+ |-------------|-----------------------|--------------------------------------------------------|
+ | WASAPI | ma_backend_wasapi | Windows Vista+ |
+ | DirectSound | ma_backend_dsound | Windows XP+ |
+ | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) |
+ | Core Audio | ma_backend_coreaudio | macOS, iOS |
+ | ALSA | ma_backend_alsa | Linux |
+ | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) |
+ | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) |
+ | sndio | ma_backend_sndio | OpenBSD |
+ | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD |
+ | OSS | ma_backend_oss | FreeBSD |
+ | AAudio | ma_backend_aaudio | Android 8+ |
+ | OpenSL|ES | ma_backend_opensl | Android (API level 16+) |
+ | Web Audio | ma_backend_webaudio | Web (via Emscripten) |
+ | Null | ma_backend_null | Cross Platform (not used on Web) |
+ |-------------|-----------------------|--------------------------------------------------------|
+
+Some backends have some nuance details you may want to be aware of.
+
+WASAPI
+------
+- Low-latency shared mode will be disabled when using an application-defined sample rate which is different to the device's native sample rate. To work around
+ this, set wasapi.noAutoConvertSRC to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing when the
+ AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM flag is specified. Setting wasapi.noAutoConvertSRC will result in miniaudio's lower quality internal resampler being used
+ instead which will in turn enable the use of low-latency shared mode.
+
+PulseAudio
+----------
+- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki:
+ https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling
+ Alternatively, consider using a different backend such as ALSA.
+
+Android
+-------
+- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest:
+ <uses-permission android:name="android.permission.RECORD_AUDIO" />
+- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a limitation with OpenSL|ES.
+- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration API (devices are enumerated through Java). You can however
+ perform your own device enumeration through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it to ma_device_init().
+- The backend API will perform resampling where possible. The reason for this as opposed to using miniaudio's built-in resampler is to take advantage of any
+ potential device-specific optimizations the driver may implement.
+
+UWP
+---
+- UWP only supports default playback and capture devices.
+- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest):
+ <Package ...>
+ ...
+ <Capabilities>
+ <DeviceCapability Name="microphone" />
+ </Capabilities>
+ </Package>
+
+Web Audio / Emscripten
+----------------------
+- You cannot use -std=c* compiler flags, nor -ansi. This only applies to the Emscripten build.
+- The first time a context is initialized it will create a global object called "miniaudio" whose primary purpose is to act as a factory for device objects.
+- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as they've been deprecated.
+- Google has implemented a policy in their browsers that prevent automatic media output without first receiving some kind of user input. The following web page
+ has additional details: https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device may fail if you try to start playback
+ without first handling some kind of user input.
+
+
+
+Miscellaneous Notes
+===================
+- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for WASAPI and Core Audio, however other backends such as
+ PulseAudio may naturally support it, though not all have been tested.
+- The contents of the output buffer passed into the data callback will always be pre-initialized to zero unless the noPreZeroedOutputBuffer config variable in
+ ma_device_config is set to true, in which case it'll be undefined which will require you to write something to the entire buffer.
+- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as ma_format_f32. If you are doing
+ clipping yourself, you can disable this overhead by setting noClip to true in the device config.
+- The sndio backend is currently only enabled on OpenBSD builds.
+- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can use it.
+- Note that GCC and Clang requires "-msse2", "-mavx2", etc. for SIMD optimizations.

-Format Conversion
-=================
-The format converter serves two purposes:
- 1) Conversion between data formats (u8 to f32, etc.)
- 2) Interleaving and deinterleaving
-When initializing a converter, you specify the input and output formats (u8, s16, etc.) and read callbacks. There are two read callbacks - one for
-interleaved input data (onRead) and another for deinterleaved input data (onReadDeinterleaved). You implement whichever is most convenient for you. You
-can implement both, but it's not recommended as it just introduces unnecessary complexity.

-Channel Routing
+DATA CONVERSION
===============
-There are two main things you can do with the channel router:
- 1) Rearrange channels
- 2) Convert from one channel count to another
-Channel Rearrangement
----------------------
-A simple example of channel rearrangement may be swapping the left and right channels in a stereo stream. To do this you just pass in the same channel
-count for both the input and output with channel maps that contain the same channels (in a different order).
+This section contains the APIs for data conversion. You will find everything here for channel mapping, sample format conversion, resampling, etc.
-Channel Conversion
-------------------
-The channel router can also convert from one channel count to another, such as converting a 5.1 stream to stero. When changing the channel count, the
-router will first perform a 1:1 mapping of channel positions that are present in both the input and output channel maps. The second thing it will do
-is distribute the input mono channel (if any) across all output channels, excluding any None and LFE channels. If there is an output mono channel, all
-input channels will be averaged, excluding any None and LFE channels.
+*************************************************************************************************************************************************************
+************************************************************************************************************************************************************/
-The last case to consider is when a channel position in the input channel map is not present in the output channel map, and vice versa. In this case the
-channel router will perform a blend of other related channels to produce an audible channel. There are several blending modes.
- 1) Simple
- Unmatched channels are silenced.
- 2) Planar Blending
- Channels are blended based on a set of planes that each speaker emits audio from.
+/**************************************************************************************************************************************************************
-Rectangular / Planar Blending
------------------------------
-In this mode, channel positions are associated with a set of planes where the channel conceptually emits audio from. An example is the front/left speaker.
-This speaker is positioned to the front of the listener, so you can think of it as emitting audio from the front plane. It is also positioned to the left
-of the listener so you can think of it as also emitting audio from the left plane. Now consider the (unrealistic) situation where the input channel map
-contains only the front/left channel position, but the output channel map contains both the front/left and front/center channel. When deciding on the audio
-data to send to the front/center speaker (which has no 1:1 mapping with an input channel) we need to use some logic based on our available input channel
-positions.
+Resampling
-As mentioned earlier, our front/left speaker is, conceptually speaking, emitting audio from the front _and_ the left planes. Similarly, the front/center
-speaker is emitting audio from _only_ the front plane. What these two channels have in common is that they are both emitting audio from the front plane.
-Thus, it makes sense that the front/center speaker should receive some contribution from the front/left channel. How much contribution depends on their
-planar relationship (thus the name of this blending technique).

+ double lpfNyquistFactor; /* 0..1. Defaults to 1. 1 = Half the sampling frequency (Nyquist Frequency), 0.5 = Quarter the sampling frequency (half Nyquest Frequency), etc. */
+} ma_linear_resampler_config;
-Because the front/left channel is emitting audio from two planes (front and left), you can think of it as though it's willing to dedicate 50% of it's total
-volume to each of it's planes (a channel position emitting from 1 plane would be willing to given 100% of it's total volume to that plane, and a channel
-position emitting from 3 planes would be willing to given 33% of it's total volume to each plane). Similarly, the front/center speaker is emitting audio
-from only one plane so you can think of it as though it's willing to _take_ 100% of it's volume from front plane emissions. Now, since the front/left
-channel is willing to _give_ 50% of it's total volume to the front plane, and the front/center speaker is willing to _take_ 100% of it's total volume
-from the front, you can imagine that 50% of the front/left speaker will be given to the front/center speaker.

/************************************************************************************************************************************************************
Ring Buffer
-===========
-Features
---------
-- Lock free (assuming single producer, single consumer)
-- Support for interleaved and deinterleaved streams
-- Allows the caller to allocate their own block of memory
-
-Usage
------
-- Call ma_rb_init() to initialize a simple buffer, with an optional pre-allocated buffer. If you pass in NULL
- for the pre-allocated buffer, it will be allocated for you and free()'d in ma_rb_uninit(). If you pass in
- your own pre-allocated buffer, free()-ing is left to you.
-
-- Call ma_rb_init_ex() if you need a deinterleaved buffer. The data for each sub-buffer is offset from each
- other based on the stride. Use ma_rb_get_subbuffer_stride(), ma_rb_get_subbuffer_offset() and
- ma_rb_get_subbuffer_ptr() to manage your sub-buffers.
-
-- Use ma_rb_acquire_read() and ma_rb_acquire_write() to retrieve a pointer to a section of the ring buffer.
- You specify the number of bytes you need, and on output it will set to what was actually acquired. If the
- read or write pointer is positioned such that the number of bytes requested will require a loop, it will be
- clamped to the end of the buffer. Therefore, the number of bytes you're given may be less than the number
- you requested.
-
-- After calling ma_rb_acquire_read/write(), you do your work on the buffer and then "commit" it with
- ma_rb_commit_read/write(). This is where the read/write pointers are updated. When you commit you need to
- pass in the buffer that was returned by the earlier call to ma_rb_acquire_read/write() and is only used
- for validation. The number of bytes passed to ma_rb_commit_read/write() is what's used to increment the
- pointers.
-
-- If you want to correct for drift between the write pointer and the read pointer you can use a combination
- of ma_rb_pointer_distance(), ma_rb_seek_read() and ma_rb_seek_write(). Note that you can only move the
- pointers forward, and you should only move the read pointer forward via the consumer thread, and the write
- pointer forward by the producer thread. If there is too much space between the pointers, move the read
- pointer forward. If there is too little space between the pointers, move the write pointer forward.
-
-
-Notes
------
-- Thread safety depends on a single producer, single consumer model. Only one thread is allowed to write, and
- only one thread is allowed to read. The producer is the only one allowed to move the write pointer, and the
- consumer is the only one allowed to move the read pointer.
-- Operates on bytes. Use ma_pcm_rb to operate in terms of PCM frames.
-- Maximum buffer size in bytes is 0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1) because of reasons.
-

The callback for processing audio data from the device.
-pOutput is a pointer to a buffer that will receive audio data that will later be played back through the speakers. This will be non-null
-for a playback or full-duplex device and null for a capture device.
+The data callback is fired by miniaudio whenever the device needs to have more data delivered to a playback device, or when a capture device has some data
+available. This is called as soon as the backend asks for more data which means it may be called with inconsistent frame counts. You cannot assume the
+callback will be fired with a consistent frame count.
-pInput is a pointer to a buffer containing input data from the device. This will be non-null for a capture or full-duplex device, and
-null for a playback device.
-frameCount is the number of PCM frames to process. If an output buffer is provided (pOutput is not null), applications should write out
-to the entire output buffer. Note that frameCount will not necessarily be exactly what you asked for when you initialized the deviced.
-The bufferSizeInFrames and bufferSizeInMilliseconds members of the device config are just hints, and are not necessarily exactly what
-you'll get.
+Parameters
+----------
+pDevice (in)
+ A pointer to the relevant device.
-Do _not_ call any miniaudio APIs from the callback. Attempting the stop the device can result in a deadlock. The proper way to stop the
-device is to call ma_device_stop() from a different thread, normally the main application thread.
+pOutput (out)
+ A pointer to the output buffer that will receive audio data that will later be played back through the speakers. This will be non-null for a playback or
+ full-duplex device and null for a capture and loopback device.
+
+pInput (in)
+ A pointer to the buffer containing input data from a recording device. This will be non-null for a capture, full-duplex or loopback device and null for a

+ not assume this will always be the same value each time the callback is fired.
+
+
+Remarks
+-------
+You cannot stop and start the device from inside the callback or else you'll get a deadlock. You must also not uninitialize the device from inside the
+callback. The following APIs cannot be called from inside the callback:
+
+ ma_device_init()
+ ma_device_init_ex()
+ ma_device_uninit()
+ ma_device_start()
+ ma_device_stop()
+

+
+The context can be configured via the `pConfig` argument. The config object is initialized with `ma_context_config_init()`. Individual configuration settings
+can then be set directly on the structure. Below are the members of the `ma_context_config` object.
+
+ logCallback
+ Callback for handling log messages from miniaudio.
+
+ threadPriority
+ The desired priority to use for the audio thread. Allowable values include the following:
+
+ |--------------------------------------|
+ | Thread Priority |
+ |--------------------------------------|
+ | ma_thread_priority_idle |
+ | ma_thread_priority_lowest |
+ | ma_thread_priority_low |
+ | ma_thread_priority_normal |
+ | ma_thread_priority_high |
+ | ma_thread_priority_highest (default) |
+ | ma_thread_priority_realtime |
+ | ma_thread_priority_default |
+ |--------------------------------------|
+
+ pUserData
+ A pointer to application-defined data. This can be accessed from the context object directly such as `context.pUserData`.
+
+ allocationCallbacks
+ Structure containing custom allocation callbacks. Leaving this at defaults will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. These allocation
+ callbacks will be used for anything tied to the context, including devices.
+
+ alsa.useVerboseDeviceEnumeration
+ ALSA will typically enumerate many different devices which can be intrusive and unuser-friendly. To combat this, miniaudio will enumerate only unique
+ card/device pairs by default. The problem with this is that you lose a bit of flexibility and control. Setting alsa.useVerboseDeviceEnumeration makes
+ it so the ALSA backend includes all devices. Defaults to false.
+
+ pulse.pApplicationName
+ PulseAudio only. The application name to use when initializing the PulseAudio context with `pa_context_new()`.
+
+ pulse.pServerName
+ PulseAudio only. The name of the server to connect to with `pa_context_connect()`.
+
+ pulse.tryAutoSpawn
+ PulseAudio only. Whether or not to try automatically starting the PulseAudio daemon. Defaults to false. If you set this to true, keep in mind that
+ miniaudio uses a trial and error method to find the most appropriate backend, and this will result in the PulseAudio daemon starting which may be
+ intrusive for the end user.
+
+ coreaudio.sessionCategory
+ iOS only. The session category to use for the shared AudioSession instance. Below is a list of allowable values and their Core Audio equivalents.
+
+ |-----------------------------------------|-------------------------------------|
+ | miniaudio Token | Core Audio Token |

+ |---------------------------------------------------------------------------|------------------------------------------------------------------|
+
+ jack.pClientName
+ The name of the client to pass to `jack_client_open()`.
+
+ jack.tryStartServer
+ Whether or not to try auto-starting the JACK server. Defaults to false.
+
+
+It is recommended that only a single context is active at any given time because it's a bulky data structure which performs run-time linking for the
+relevant backends every time it's initialized.
+
+The location of the context cannot change throughout it's lifetime. Consider allocating the `ma_context` object with `malloc()` if this is an issue. The
+reason for this is that a pointer to the context is stored in the `ma_device` structure.
+
+
+Example 1 - Default Initialization
+----------------------------------
+The example below shows how to initialize the context using the default configuration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {+ // Error.
+}
+```
+
+
+Example 2 - Custom Configuration
+--------------------------------
+The example below shows how to initialize the context using custom backend priorities and a custom configuration. In this hypothetical example, the program
+wants to prioritize ALSA over PulseAudio on Linux. They also want to avoid using the WinMM backend on Windows because it's latency is too high. They also
+want an error to be returned if no valid backend is available which they achieve by excluding the Null backend.
+
+For the configuration, the program wants to capture any log messages so they can, for example, route it to a log file and user interface.
+
+```c
+ma_backend backends[] = {+ ma_backend_alsa,
+ ma_backend_pulseaudio,
+ ma_backend_wasapi,
+ ma_backend_dsound
+};
+
+ma_context_config config = ma_context_config_init();
+config.logCallback = my_log_callback;
+config.pUserData = pMyUserData;
+
+ma_context context;
+ma_result result = ma_context_init(backends, sizeof(backends)/sizeof(backends[0]), &config, &context);
+if (result != MA_SUCCESS) {+ // Error.
+ if (result == MA_NO_BACKEND) {+ // Couldn't find an appropriate backend.
+ }

Initializes a device.
-The context can be null in which case it uses the default. This is equivalent to passing in a
-context that was initialized like so:
+A device represents a physical audio device. The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it
+from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be
+playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the
+device is done via a callback which is fired by miniaudio at periodic time intervals.
+The frequency at which data is deilvered to and from a device depends on the size of it's period which is defined by a buffer size and a period count. The size
+of the buffer can be defined in terms of PCM frames or milliseconds, whichever is more convenient. The size of a period is the size of this buffer, divided by
+the period count. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and increased risk of glitching due to
+the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but miniaudio's defaults should work fine for
+most scenarios. If you're building a game you should leave this fairly small, whereas if you're building a simple media player you can make it larger. Note
+that the period size you request is actually just a hint - miniaudio will tell the backend what you want, but the backend is ultimately responsible for what it
+gives you. You cannot assume you will get exactly what you ask for.
+
+When delivering data to and from a device you need to make sure it's in the correct format which you can set through the device configuration. You just set the
+format that you want to use and miniaudio will perform all of the necessary conversion for you internally. When delivering data to and from the callback you
+can assume the format is the same as what you requested when you initialized the device. See Remarks for more details on miniaudio's data conversion pipeline.
+
+
+Parameters
+----------
+pContext (in, optional)
+ A pointer to the context that owns the device. This can be null, in which case it creates a default context internally.
+
+pConfig (in)
+ A pointer to the device configuration. Cannot be null. See remarks for details.
+
+pDevice (out)
+ A pointer to the device object being initialized.
+
+
+Return Value
+------------
+MA_SUCCESS if successful; any other error code otherwise.
+
+
+Thread Safety
+-------------
+Unsafe. It is not safe to call this function simultaneously for different devices because some backends depend on and mutate global state. The same applies to
+calling this at the same time as `ma_device_uninit()`.
+
+
+Callback Safety
+---------------
+Unsafe. It is not safe to call this inside any callback.
+
+
+Remarks
+-------
+Setting `pContext` to NULL will result in miniaudio creating a default context internally and is equivalent to passing in a context initialized like so:
+
+ ```c
ma_context_init(NULL, 0, NULL, &context);
+ ```
-Do not pass in null for the context if you are needing to open multiple devices. You can,
-however, use null when initializing the first device, and then use device.pContext for the
-initialization of other devices.
+Do not set `pContext` to NULL if you are needing to open multiple devices. You can, however, use NULL when initializing the first device, and then use
+device.pContext for the initialization of other devices.
-The device's configuration is controlled with pConfig. This allows you to configure the sample
-format, channel count, sample rate, etc. Before calling ma_device_init(), you will need to
-initialize a ma_device_config object using ma_device_config_init(). You must set the callback in
-the device config. Once initialized, the device's config is immutable. If you need to change the
-config you will need to initialize a new device.
+The device can be configured via the `pConfig` argument. The config object is initialized with `ma_device_config_init()`. Individual configuration settings can
+then be set directly on the structure. Below are the members of the `ma_device_config` object.
-Passing in 0 to any property in pConfig will force the use of a default value. In the case of
-sample format, channel count, sample rate and channel map it will default to the values used by
-the backend's internal device. For the size of the buffer you can set bufferSizeInFrames or
-bufferSizeInMilliseconds (if both are set it will prioritize bufferSizeInFrames). If both are
-set to zero, it will default to MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY or
-MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE, depending on whether or not performanceProfile
-is set to ma_performance_profile_low_latency or ma_performance_profile_conservative.
+ deviceType
+ Must be `ma_device_type_playback`, `ma_device_type_capture`, `ma_device_type_duplex` of `ma_device_type_loopback`.
-If you request exclusive mode and the backend does not support it an error will be returned. For
-robustness, you may want to first try initializing the device in exclusive mode, and then fall back
-to shared mode if required. Alternatively you can just request shared mode (the default if you
-leave it unset in the config) which is the most reliable option. Some backends do not have a
-practical way of choosing whether or not the device should be exclusive or not (ALSA, for example)
-in which case it just acts as a hint. Unless you have special requirements you should try avoiding
-exclusive mode as it's intrusive to the user. Starting with Windows 10, miniaudio will use low-latency
-shared mode where possible which may make exclusive mode unnecessary.
+ sampleRate
+ The sample rate, in hertz. The most common sample rates are 48000 and 44100. Setting this to 0 will use the device's native sample rate.
-When sending or receiving data to/from a device, miniaudio will internally perform a format
-conversion to convert between the format specified by pConfig and the format used internally by
-the backend. If you pass in NULL for pConfig or 0 for the sample format, channel count,
-sample rate _and_ channel map, data transmission will run on an optimized pass-through fast path.
+ periodSizeInFrames
+ The desired size of a period in PCM frames. If this is 0, `periodSizeInMilliseconds` will be used instead. If both are 0 the default buffer size will
+ be used depending on the selected performance profile. This value affects latency. See below for details.
-The buffer size should be treated as a hint. miniaudio will try it's best to use exactly what you
-ask for, but it may differ. You should not assume the number of frames specified in each call to
-the data callback is exactly what you originally specified.
+ periodSizeInMilliseconds
+ The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be
+ used depending on the selected performance profile. The value affects latency. See below for details.
-The <periods> property controls how frequently the background thread is woken to check for more
-data. It's tied to the buffer size, so as an example, if your buffer size is equivalent to 10
-milliseconds and you have 2 periods, the CPU will wake up approximately every 5 milliseconds.
+ periods
+ The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by
+ this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured.
-When compiling for UWP you must ensure you call this function on the main UI thread because the
-operating system may need to present the user with a message asking for permissions. Please refer
-to the official documentation for ActivateAudioInterfaceAsync() for more information.
+ performanceProfile
+ A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or
+ `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value.
-ALSA Specific: When initializing the default device, requesting shared mode will try using the
-"dmix" device for playback and the "dsnoop" device for capture. If these fail it will try falling
-back to the "hw" device.
+ noPreZeroedOutputBuffer
+ When set to true, the contents of the output buffer passed into the data callback will be left undefined. When set to false (default), the contents of
+ the output buffer will be cleared the zero. You can use this to avoid the overhead of zeroing out the buffer if you know can guarantee that your data
+ callback will write to every sample in the output buffer, or if you are doing your own clearing.
-Return Value:
- MA_SUCCESS if successful; any other error code otherwise.
+ noClip
+ When set to true, the contents of the output buffer passed into the data callback will be clipped after returning. When set to false (default), the
+ contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or not the clip. This only
+ applies when the playback sample format is f32.
-Thread Safety: UNSAFE
- It is not safe to call this function simultaneously for different devices because some backends
- depend on and mutate global state (such as OpenSL|ES). The same applies to calling this at the
- same time as ma_device_uninit().
+ dataCallback
+ The callback to fire whenever data is ready to be delivered to or from the device.
+
+ stopCallback
+ The callback to fire whenever the device has stopped, either explicitly via `ma_device_stop()`, or implicitly due to things like the device being
+ disconnected.
+
+ pUserData
+ The user data pointer to use with the device. You can access this directly from the device object like `device.pUserData`.
+
+ resampling.algorithm
+ The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The
+ default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`.
+
+ resampling.linear.lpfOrder
+ The linear resampler applies a low-pass filter as part of it's procesing for anti-aliasing. This setting controls the order of the filter. The higher
+ the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is
+ `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`.
+
+ playback.pDeviceID
+ A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
+ default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+ playback.format
+ The sample format to use for playback. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+ initialization from the device object directly with `device.playback.format`.
+
+ playback.channels
+ The number of channels to use for playback. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+ from the device object directly with `device.playback.channels`.
+
+ playback.channelMap
+ The channel map to use for playback. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+ device object direct with `device.playback.channelMap`.
+
+ playback.shareMode
+ The preferred share mode to use for playback. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+ exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired.
+
+ playback.pDeviceID
+ A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize. Setting this NULL (default) will use the system's
+ default playback device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration.
+
+ capture.format
+ The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used. This can be retrieved after
+ initialization from the device object directly with `device.capture.format`.
+
+ capture.channels
+ The number of channels to use for capture. When set to 0 the device's native channel count will be used. This can be retrieved after initialization
+ from the device object directly with `device.capture.channels`.
+
+ capture.channelMap
+ The channel map to use for capture. When left empty, the device's native channel map will be used. This can be retrieved after initialization from the
+ device object direct with `device.capture.channelMap`.
+
+ capture.shareMode
+ The preferred share mode to use for capture. Can be either `ma_share_mode_shared` (default) or `ma_share_mode_exclusive`. Note that if you specify
+ exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired.
+
+ wasapi.noAutoConvertSRC
+ WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false.
+
+ wasapi.noDefaultQualitySRC
+ WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false. When set to true, disables the use of `AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY`.
+ You should usually leave this set to false, which is the default.
+
+ wasapi.noAutoStreamRouting
+ WASAPI only. When set to true, disables automatic stream routing on the WASAPI backend. Defaults to false.
+
+ wasapi.noHardwareOffloading
+ WASAPI only. When set to true, disables the use of WASAPI's hardware offloading feature. Defaults to false.
+
+ alsa.noMMap
+ ALSA only. When set to true, disables MMap mode. Defaults to false.
+
+ pulse.pStreamNamePlayback
+ PulseAudio only. Sets the stream name for playback.
+
+ pulse.pStreamNameCapture
+ PulseAudio only. Sets the stream name for capture.
+
+
+Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device.
+
+If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or
+`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or
+`ma_performance_profile_conservative`.
+
+If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device
+in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the
+config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA,
+for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user.
+Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary.
+
+After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`.
+
+When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by pConfig and
+the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run on
+an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`,
+`playback/capture.channels` and `sampleRate` members of the device object.
+
+When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message
+asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information.
+
+ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture.
+If these fail it will try falling back to the "hw" device.
+
+
+Example 1 - Simple Initialization
+---------------------------------
+This example shows how to initialize a simple playback default using a standard configuration. If you are just needing to do simple playback from the default
+playback device this is usually all you need.
+
+```c
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.format = ma_format_f32;
+config.playback.channels = 2;
+config.sampleRate = 48000;
+config.dataCallback = ma_data_callback;
+config.pMyUserData = pMyUserData;
+
+ma_device device;
+ma_result result = ma_device_init(NULL, &config, &device);
+if (result != MA_SUCCESS) {+ // Error
+}
+```
+
+
+Example 2 - Advanced Initialization
+-----------------------------------
+This example show how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size
+and period count. We also want to allow the user to be able to choose which device to output from which means we need a context so we can perform device
+enumeration.
+
+```c
+ma_context context;
+ma_result result = ma_context_init(NULL, 0, NULL, &context);
+if (result != MA_SUCCESS) {+ // Error
+}
+
+ma_device_info* pPlaybackDeviceInfos;
+ma_uint32 playbackDeviceCount;
+result = ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, NULL, NULL);
+if (result != MA_SUCCESS) {+ // Error
+}
+
+// ... choose a device from pPlaybackDeviceInfos ...
+
+ma_device_config config = ma_device_config_init(ma_device_type_playback);
+config.playback.pDeviceID = pMyChosenDeviceID; // <-- Get this from the `id` member of one of the `ma_device_info` objects returned by ma_context_get_devices().
+config.playback.format = ma_format_f32;
+config.playback.channels = 2;
+config.sampleRate = 48000;
+config.dataCallback = ma_data_callback;
+config.pUserData = pMyUserData;
+config.periodSizeInMilliseconds = 10;
+config.periods = 3;
+
+ma_device device;
+result = ma_device_init(&context, &config, &device);
+if (result != MA_SUCCESS) {+ // Error
+}
+```

+ Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
+ the following output configuration:
+
+ - front/left
+ - side/left
+ - back/left
+
+ The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
+ of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
+
+ Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
+ speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
+ from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
+ receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
+ the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
+ across 3 spatial dimensions.
+
+ The first thing to do is figure out how each speaker's volume is spread over each of plane:
+ - front/left: 2 planes (front and left) = 1/2 = half it's total volume on each plane
+ - side/left: 1 plane (left only) = 1/1 = entire volume from left plane
+ - back/left: 2 planes (back and left) = 1/2 = half it's total volume on each plane
+ - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
+
+ The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
+ channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
+ taken by the other to produce the final contribution.

- Imagine the following simplified example: You have a single input speaker which is the front/left speaker which you want to convert to
- the following output configuration:
-
- - front/left
- - side/left
- - back/left
-
- The front/left output is easy - it the same speaker position so it receives the full contribution of the front/left input. The amount
- of contribution to apply to the side/left and back/left speakers, however, is a bit more complicated.
-
- Imagine the front/left speaker as emitting audio from two planes - the front plane and the left plane. You can think of the front/left
- speaker emitting half of it's total volume from the front, and the other half from the left. Since part of it's volume is being emitted
- from the left side, and the side/left and back/left channels also emit audio from the left plane, one would expect that they would
- receive some amount of contribution from front/left speaker. The amount of contribution depends on how many planes are shared between
- the two speakers. Note that in the examples below I've added a top/front/left speaker as an example just to show how the math works
- across 3 spatial dimensions.
-
- The first thing to do is figure out how each speaker's volume is spread over each of plane:
- - front/left: 2 planes (front and left) = 1/2 = half it's total volume on each plane
- - side/left: 1 plane (left only) = 1/1 = entire volume from left plane
- - back/left: 2 planes (back and left) = 1/2 = half it's total volume on each plane
- - top/front/left: 3 planes (top, front and left) = 1/3 = one third it's total volume on each plane
-
- The amount of volume each channel contributes to each of it's planes is what controls how much it is willing to given and take to other
- channels on the same plane. The volume that is willing to the given by one channel is multiplied by the volume that is willing to be
- taken by the other to produce the final contribution.

-Sinc Sample Rate Conversion
-===========================
-
-The sinc SRC algorithm uses a windowed sinc to perform interpolation of samples. Currently, miniaudio's implementation supports rectangular and Hann window
-methods.
-
-Whenever an output sample is being computed, it looks at a sub-section of the input samples. I've called this sub-section in the code below the "window",
-which I realize is a bit ambigous with the mathematical "window", but it works for me when I need to conceptualize things in my head. The window is made up
-of two halves. The first half contains past input samples (initialized to zero), and the second half contains future input samples. As time moves forward
-and input samples are consumed, the window moves forward. The larger the window, the better the quality at the expense of slower processing. The window is
-limited the range [MA_SRC_SINC_MIN_WINDOW_WIDTH, MA_SRC_SINC_MAX_WINDOW_WIDTH] and defaults to MA_SRC_SINC_DEFAULT_WINDOW_WIDTH.
-
-Input samples are cached for efficiency (to prevent frequently requesting tiny numbers of samples from the client). When the window gets to the end of the
-cache, it's moved back to the start, and more samples are read from the client. If the client has no more data to give, the cache is filled with zeros and
-the last of the input samples will be consumed. Once the last of the input samples have been consumed, no more samples will be output.
-
-
-When reading output samples, we always first read whatever is already in the input cache. Only when the cache has been fully consumed do we read more data
-from the client.
-
-To access samples in the input buffer you do so relative to the window. When the window itself is at position 0, the first item in the buffer is accessed
-with "windowPos + windowWidth". Generally, to access any sample relative to the window you do "windowPos + windowWidth + sampleIndexRelativeToWindow".

- In general, this is the pipeline used for data conversion. Note that this can actually change which is explained later.
-
- Pre Format Conversion -> Sample Rate Conversion -> Channel Routing -> Post Format Conversion
-
- Pre Format Conversion
- ---------------------
- This is where the sample data is converted to a format that's usable by the later stages in the pipeline. Input data
- is converted to deinterleaved floating-point.
-
- Channel Routing
- ---------------
- Channel routing is where stereo is converted to 5.1, mono is converted to stereo, etc. This stage depends on the
- pre format conversion stage.
-
- Sample Rate Conversion
- ----------------------
- Sample rate conversion depends on the pre format conversion stage and as the name implies performs sample rate conversion.
-
- Post Format Conversion
- ----------------------
- This stage is where our deinterleaved floating-point data from the previous stages are converted to the requested output
- format.
-
-
- Optimizations
- -------------
- Sometimes the conversion pipeline is rearranged for efficiency. The first obvious optimization is to eliminate unnecessary
- stages in the pipeline. When no channel routing nor sample rate conversion is necessary, the entire pipeline is optimized
- down to just this:
-
- Post Format Conversion
-
- When sample rate conversion is not unnecessary:
-
- Pre Format Conversion -> Channel Routing -> Post Format Conversion
-
- When channel routing is unnecessary:
-
- Pre Format Conversion -> Sample Rate Conversion -> Post Format Conversion
-
- A slightly less obvious optimization is used depending on whether or not we are increasing or decreasing the number of
- channels. Because everything in the pipeline works on a per-channel basis, the efficiency of the pipeline is directly
- proportionate to the number of channels that need to be processed. Therefore, it's can be more efficient to move the
- channel conversion stage to an earlier or later stage. When the channel count is being reduced, we move the channel
- conversion stage to the start of the pipeline so that later stages can work on a smaller number of channels at a time.
- Otherwise, we move the channel conversion stage to the end of the pipeline. When reducing the channel count, the pipeline
- will look like this:
-
- Pre Format Conversion -> Channel Routing -> Sample Rate Conversion -> Post Format Conversion
-
- Notice how the Channel Routing and Sample Rate Conversion stages are swapped so that the SRC stage has less data to process.

-BACKEND IMPLEMENTATION GUIDELINES
-=================================
-Context
--------
-- Run-time linking if possible.
-- Set whether or not it's an asynchronous backend
+MAJOR CHANGES IN VERSION 0.9
+============================
+Version 0.9 includes major API changes, centered mostly around full-duplex and the rebrand to "miniaudio". Before I go into
+detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think
+it's best to get these changes out of the way now while the library is still relatively young and unknown.
-Device
-------
-- If a full-duplex device is requested and the backend does not support full duplex devices, have ma_device_init__[backend]()
- return MA_DEVICE_TYPE_NOT_SUPPORTED.
-- If exclusive mode is requested, but the backend does not support it, return MA_SHARE_MODE_NOT_SUPPORTED. If practical, try
- not to fall back to a different share mode - give the client exactly what they asked for. Some backends, such as ALSA, may
- not have a practical way to distinguish between the two.
-- If pDevice->usingDefault* is set, prefer the device's native value if the backend supports it. Otherwise use the relevant
- value from the config.
-- If the configs buffer size in frames is 0, set it based on the buffer size in milliseconds, keeping in mind to handle the
- case when the default sample rate is being used where practical.
-- Backends must set the following members of pDevice before returning successfully from ma_device_init__[backend]():
- - internalFormat
- - internalChannels
- - internalSampleRate
- - internalChannelMap
- - bufferSizeInFrames
- - periods
+There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in
+advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for
+you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes).
+
+
+Rebranding to "miniaudio"
+-------------------------
+The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple:
+
+1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and
+2) I don't like the look of the underscore.
+
+This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's
+better to get this out of the road now rather than later. Also, since there are necessary API changes for full-duplex support
+I think it's better to just get the namespace change over and done with at the same time as the full-duplex changes. I'm hoping
+this will be the last of the major API changes. Fingers crossed!
+
+The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's
+your preference.
+
+
+Full-Duplex Support
+-------------------
+The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes.
+
+1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted
+ to avoid a third callback just for full-duplex so the decision was made to break this API and unify the callbacks. Now,
+ there is just one callback which is the same for all three modes (playback, capture, duplex). The new callback looks like
+ the following:
+
+ void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount);
+
+ This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In
+ playback-only mode, pInput will be null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer
+ returned from the callback since it's not necessary for miniaudio anymore.
+
+2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client
+ to choose a different PCM format for the playback and capture sides. The old ma_device_config object simply did not allow
+ this and needed to change. With these changes you now specify the device ID, format, channels, channel map and share mode
+ on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture.
+
+ Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now,
+ the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking
+ just the context, device config and a pointer to the device object being initialized. The rationale for this change is that
+ it just makes more sense to me that these are set as part of the config like everything else.
+
+ Example device initialization:
+
+ ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture.
+ config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device.
+ config.playback.format = ma_format_f32;
+ config.playback.channels = 2;
+ config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device.
+ config.capture.format = ma_format_s16;
+ config.capture.channels = 1;
+ config.sampleRate = 44100;
+ config.dataCallback = data_callback;
+ config.pUserData = &myUserData;
+
+ result = ma_device_init(&myContext, &config, &device);
+ if (result != MA_SUCCESS) {+ ... handle error ...
+ }
+
+ Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has
+ been renamed to "stopCallback".
+
+This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample
+rate conversion is required for the playback device:
+ - Core Audio
+ - JACK
+ - AAudio
+ - OpenSL
+ - WebAudio
+
+In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such
+thorough testing. If you experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample
+program that reproduces the issue if possible).
+
+
+Other API Changes
+-----------------
+In addition to the above, the following API changes have been made:
+
+- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization.
+- The onLogCallback member of ma_context_config has been renamed to "logCallback".
+- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message)
+ - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it.
+- Some APIs have been renamed:
+ - mal_decoder_read() -> ma_decoder_read_pcm_frames()
+ - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame()
+ - mal_sine_wave_read() -> ma_sine_wave_read_f32()
+ - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex()
+- Some APIs have been removed:
+ - mal_device_get_buffer_size_in_bytes()
+ - mal_device_set_recv_callback()
+ - mal_device_set_send_callback()
+ - mal_src_set_input_sample_rate()
+ - mal_src_set_output_sample_rate()
+- Error codes have been rearranged. If you're a binding maintainer you will need to update.
+- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection
+ and to make it easier to see the priority. If you're a binding maintainer you will need to update.
+- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with
+ some future planned high-level APIs.
+- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that
+ the pointer comes before the count. The rationale for this is to keep it consistent with things like memcpy().
+
+
+Miscellaneous Changes
+---------------------
+The following miscellaneous changes have also been made.
+
+- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the
+ record, this is one of the nicest audio APIs out there, just behind the BSD audio APIs).
+- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL.
+- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio
+ was not explicitly supported. These are no longer needed and have therefore been removed.
+- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an
+ exclusive mode device, or an error. The rationale for this change is to give the client more control over how to handle cases
+ when the desired shared mode is unavailable.
+- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb"
+ operates on PCM frames.
+- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but
+ removes the attribution requirement. The rationale for this is to support countries that don't recognize public domain.
