+Audio Buffers
+=============
+miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can read from both memory that's managed by the application, but
+can also handle the memory management for you internally. The way memory is managed is flexible and should support most use cases.
+
+Audio buffers are initialised using the standard configuration system used everywhere in miniaudio:
+
+ ```c
+ ma_audio_buffer_config config = ma_audio_buffer_config_init(format, channels, sizeInFrames, pExistingData, &allocationCallbacks);
+ ma_audio_buffer buffer;
+ result = ma_audio_buffer_init(&config, &buffer);
+ if (result != MA_SUCCESS) {+ // Error.
+ }
+
+ ...
+
+ ma_audio_buffer_uninit(&buffer);
+ ```
+
+In the example above, the memory pointed to by `pExistingData` will _not_ be copied which is how an application can handle memory allocations themselves. If
+you would rather make a copy of the data, use `ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`.
+
+Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure _and_ the raw audio data in a contiguous block of memory. That is,
+the raw audio data will be located immediately after the `ma_audio_buffer` structure. To do this, use `ma_audio_buffer_alloc_and_init()`:
+
+ ```c
+ ma_audio_buffer* pBuffer
+ result = ma_audio_buffer_alloc_and_init(&config, &pBuffer);
+ if (result != MA_SUCCESS) {+ // Error
+ }
+
+ ...
+
+ ma_audio_buffer_uninit_and_free(&buffer);
+ ```
+
+If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it with `ma_audio_buffer_uninit_and_free()`.
+
+An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the cursor moves forward. It does not automatically loop back to
+the start. To do this, you should inspect the number of frames returned by `ma_audio_buffer_read_pcm_frames()` to determine if the end has been reached, which
+you can know by comparing it with the requested frame count you specified when you called the function. If the return value is less it means the end has been
+reached. In this case you can seem back to the start with `ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an
+audio buffer.
+
+ ```c
+ ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping);
+ if (framesRead < desiredFrameCount) {+ // If not looping, this means the end has been reached. This should never happen in looping mode with valid input.
+ }
+ ```
+
+Sometimes you may want to avoid the cost of data movement between the internal buffer and the output buffer as it's just a copy operation. Instead you can use
+memory mapping to retrieve a pointer to a segment of data:
+
+ ```c
+ void* pMappedFrames;
+ ma_uint64 frameCount = frameCountToTryMapping;
+ ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount);
+ if (result == MA_SUCCESS) {+ // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be less due to the end of the buffer being reached.
+ ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels);
+
+ // You must unmap the buffer.
+ ma_audio_buffer_unmap(pAudioBuffer, frameCount);
+ }
+ ```
+
+When you use memory mapping, the read cursor is increment by the frame count passed in to `ma_audio_buffer_unmap()`. If you decide not to process every frame
+you can pass in a value smaller than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is that it does not handle looping
+for you. You can determine if the buffer is at the end for the purpose of looping with `ma_audio_buffer_at_end()`.
+
+
+

+Logging Levels
+==============
+A log level will automatically include the lower levels. For example, verbose logging will enable everything. The warning log level will only include warnings
+and errors, but will ignore informational and verbose logging. If you only want to handle a specific log level, implement a custom log callback (see
+ma_context_init() for details) and interrogate the `logLevel` parameter.
+
+By default the log level will be set to MA_LOG_LEVEL_ERROR, but you can change this by defining MA_LOG_LEVEL before the implementation of miniaudio.
+
+MA_LOG_LEVEL_VERBOSE
+ Mainly intended for debugging. This will enable all log levels and can be triggered from within the data callback so care must be taken when enabling this
+ in production environments.
+
+MA_LOG_LEVEL_INFO
+ Informational logging. Useful for debugging. This will also enable warning and error logs. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_WARNING
+ Warnings. You should enable this in you development builds and action them when encounted. This will also enable error logs. These logs usually indicate a
+ potential problem or misconfiguration, but still allow you to keep running. This will never be called from within the data callback.
+
+MA_LOG_LEVEL_ERROR
+ Error logging. This will be fired when an operation fails and is subsequently aborted. This can be fired from within the data callback, in which case the
+ device will be stopped. You should always have this log level enabled.

a full decode right from the start of the stream. Later on I'll need to write a layer that goes through all of the Ogg pages until we
find the one containing the sample we need. Then we know exactly where to seek for stb_vorbis.

REVISION HISTORY
-================
+================
+v0.10.9 - 2020-06-24
+ - Amalgamation of dr_wav, dr_flac and dr_mp3. With this change, including the header section of these libraries before the implementation of miniaudio is no
+ longer required. Decoding of WAV, FLAC and MP3 should be supported seamlessly without any additional libraries. Decoders can be excluded from the build
+ with the following options:
+ - MA_NO_WAV
+ - MA_NO_FLAC
+ - MA_NO_MP3
+ If you get errors about multiple definitions you need to either enable the options above, move the implementation of dr_wav, dr_flac and/or dr_mp3 to before
+ the implementation of miniaudio, or update dr_wav, dr_flac and/or dr_mp3.
+ - Changes to the internal atomics library. This has been replaced with c89atomic.h which is embedded within this file.
+ - Fix a bug when a decoding backend reports configurations outside the limits of miniaudio's decoder abstraction.
+ - Fix the UWP build.
+ - Fix the Core Audio build.
+ - Fix the -std=c89 build on GCC.
+
+v0.10.8 - 2020-06-22
+ - Remove dependency on ma_context from mutexes.
+ - Change ma_data_source_read_pcm_frames() to return a result code and output the frames read as an output parameter.
+ - Change ma_data_source_seek_pcm_frames() to return a result code and output the frames seeked as an output parameter.
+ - Change ma_audio_buffer_unmap() to return MA_AT_END when the end has been reached. This should be considered successful.
+ - Change playback.pDeviceID and capture.pDeviceID to constant pointers in ma_device_config.
+ - Add support for initializing decoders from a virtual file system object. This is achieved via the ma_vfs API and allows the application to customize file
+ IO for the loading and reading of raw audio data. Passing in NULL for the VFS will use defaults. New APIs:
+ - ma_decoder_init_vfs()
+ - ma_decoder_init_vfs_wav()
+ - ma_decoder_init_vfs_flac()
+ - ma_decoder_init_vfs_mp3()
+ - ma_decoder_init_vfs_vorbis()
+ - ma_decoder_init_vfs_w()
+ - ma_decoder_init_vfs_wav_w()
+ - ma_decoder_init_vfs_flac_w()
+ - ma_decoder_init_vfs_mp3_w()
+ - ma_decoder_init_vfs_vorbis_w()
+ - Add support for memory mapping to ma_data_source.
+ - ma_data_source_map()
+ - ma_data_source_unmap()
+ - Add ma_offset_pcm_frames_ptr() and ma_offset_pcm_frames_const_ptr() which can be used for offsetting a pointer by a specified number of PCM frames.
+ - Add initial implementation of ma_yield() which is useful for spin locks which will be used in some upcoming work.
+ - Add documentation for log levels.
+ - The ma_event API has been made public in preparation for some uncoming work.
+ - Fix a bug in ma_decoder_seek_to_pcm_frame() where the internal sample rate is not being taken into account for determining the seek location.
+ - Fix some bugs with the linear resampler when dynamically changing the sample rate.
+ - Fix compilation errors with MA_NO_DEVICE_IO.
+ - Fix some warnings with GCC and -std=c89.
+ - Fix some formatting warnings with GCC and -Wall and -Wpedantic.
+ - Fix some warnings with VC6.
+ - Minor optimization to ma_copy_pcm_frames(). This is now a no-op when the input and output buffers are the same.
+
+v0.10.7 - 2020-05-25
+ - Fix a compilation error in the C++ build.
+ - Silence a warning.
+
+v0.10.6 - 2020-05-24
+ - Change ma_clip_samples_f32() and ma_clip_pcm_frames_f32() to take a 64-bit sample/frame count.
+ - Change ma_zero_pcm_frames() to clear to 128 for ma_format_u8.
+ - Add ma_silence_pcm_frames() which replaces ma_zero_pcm_frames(). ma_zero_pcm_frames() will be removed in version 0.11.
+ - Add support for u8, s24 and s32 formats to ma_channel_converter.
+ - Add compile-time and run-time version querying.
+ - MA_VERSION_MINOR
+ - MA_VERSION_MAJOR
+ - MA_VERSION_REVISION
+ - MA_VERSION_STRING
+ - ma_version()
+ - ma_version_string()
+ - Add ma_audio_buffer for reading raw audio data directly from memory.
+ - Fix a bug in shuffle mode in ma_channel_converter.
+ - Fix compilation errors in certain configurations for ALSA and PulseAudio.
+ - The data callback now initializes the output buffer to 128 when the playback sample format is ma_format_u8.
+
v0.10.5 - 2020-05-05
- Change ma_zero_pcm_frames() to take a 64-bit frame count.
- Add ma_copy_pcm_frames().
