+Change History

+--------------

+This file contains a list of all changes starting after the release of

+sox-11gamma.

+sox-12.18.3

+-----------

+  o Fix writing MP3 files on AMD64 processors.

+  o More fixes to MP3 tag reading.  Sometimes tags were

+    detected as valid MP3 frames.

+  o Add new getopt1.c to win32 project file.

+  o New optional rabbit resample routine.  Uses libsamplerate

+    (aka Secret Rabbit Code) if installed.  (Reuben Thomas)

+  o Fix to pay attention when starting of effects fails.

+    (Reuben Thomas)

+  o Fixed a bug introduced in 12.18.2 that stopped the draining

+    of effects from occuring.  This had stopped the reverse effect,

+    among others, from working.  (Reuben Thomas)

+  o Add FLAC support (robs@users.sf.net)

+  o Allow encoding quality to be specified (works for Ogg too, but not

+    MP3).

+  o bass and treble altering effects. (robs@users.sf.net)

+  o Visualisation of various filters' frequency response via Octave.

+    (robs@users.sf.net)

+  o Allow the rate and number of channels of .au files to be overridden

+    by command-line arguments. (robs@users.sf.net)

+  o More and better self-tests. (robs@users.sf.net)

+  o Support Maxis's XA format. (Dwayne C. Litzenberger)

+  o Add equalizer effect (Pascal Giard)

+  o Fix rounding error when reading command-line time

+    parameters. (robs)

+  o Allow command-line time parameters of < 1 sec to omit the

+    leading 0. (robs)

+  o Fix nul file hander ignoring other format options if rate

+    option has not been given. (robs)

+  o Fix synth length accuracy. (robs)

+  o Fix broken audio when downmixing with any of the following

+    effects: synth, deemph, vibro. (robs)

+  o Fix wav file handler discarding the last PCM sample in certain

+    circumstances. (robs)

+  o Add support for 24-bit PCM raw, wav (WAVE_FORMAT_EXTENSIBLE) [FR# 801015],

+    aiff, & flac files. (robs)

+  o Added alias -1 (for -b), -2 (for -w), -4 (for -l), -8 (for -d). (robs)

+  o Remove old, optional rate change and alaw/ulaw conversion code.

+    (Reuben Thomas)

+  o Make sox and soxmix a single binary.  (Reuben Thomas)

+  o Consistent (and hopefully complete) clipping detection and

+    reporting.  (robs)

+  o Add AIFF-C output support.  (shashimoto)

+  o -V now gives only user-relevant messages, use -V -V to get

+    developer-relevant messages.  (robs)

+  o Old and new rate code removed; the "rate" effect is implemented

+    for backwards compatibility by "resample".

+  o Preview mode now removed, as all it did was use rate rather than

+    resample, and rate has been removed.

+  o Improved synth usage (by introducing -n option) and improved synth

+    entry in the man-page.  (robs)

+  o Documented the butterworth filter effects.  (robs)

+  o Added command line options for specifying the output file

+    comment.  (robs)

+sox-12.18.2

+-----------

+  o Adding in Debian's disk full fix (#313206).

+  o Finally got rid of reference to cleanup() function in

+    library.  Applications are now required to detect

+    all failures from return codes and cleanup as they

+    want.

+  o Changed how list of formats and effects are stored internally.

+    Effects libst users only. Dirk

+  o Store effects usage so that its accessable by applications.

+    Dirk

+  o Modify the synth effect to not use SIGINT to stop processing

+    and instead return ST_EOF.  This allows exact acount of

+    samples to be written out instead of an approximate amount.

+  o Fix hangup when attempting to write stereo MP3 files.

+    (1512218) Kendrick Shaw

+  o Deemp effect would lose stereo sepeartion. (1479249)

+  o Adding cross-platform support for getopt_long

+  o Make help screens print much more information and add

+    new --help-effect option.  (Originally from Dirk).

+  o Add support for using an external gsm library instead of

+    just the internal one.  Vladimir Nadvornik

+  o Updates to nul file handler to prevent crashes during output.

+    Martin Panter (1482869)

+sox-12.18.1

+------------

+  o The "filter" effect could go into infinite drain mode.  Now

+    only drain 1 buffer.  noisered as well.

+  o SoX was ignoring user aborts (ctrl-c) if it occured during

+    effect drain operations.  This was bad if effects had

+    bugs and stuck in infinite loop.

+  o Stop SoX from crashing when file type could not be auto

+    determined (1417776).

+  o Output filenames with multiple '.' confused SoX.  (1417776)

+    Christian Hammer

+  o Moved to a common set of CLIP routines.  This fixed clipping

+    bugs in noisered and mcompand.

+  o Stop SoX from crashing on sphere files that contain large text

+    strings.  (1430025) Ulf Hamhammar

+  o Fix some overflow crashes in aiff handler. (1430024)  Ulf Hamhammar.

+  o Under windows, set piped input/output to binary mode (1417794). Martin

+    Panter

+  o Fixed broken internal version of strdup().  (1417790) Marty

+  o Stop infinite loop when reading MP3's with a tag size of

+    exactly 8192 bytes.  (1417511) Hans Fugal

+  o Fix typo in stlib.dsp for loading in Visual Studio 6.

+  o Fixed problems in silence effect related to removing multiple

+    periods of silence from the middle of the sound file.

+  o Reduced the window size greatly on the silence effect to

+    prevent leaving in silence that looked like noise still based

+    on RMS values.

+  o Prevent infinite loop in pitch effect from uninitialize variable.

+    Frank Heckenbach

+  o Prevent crashes when printing error mesages (1447239)

+  o Added makefile and support files to compile using Open Watcom

+    compiler.  (1417798) Marty

+  o Stop calling flow() on effects that returned EOF during drain().  Allows

+    two back-to-back reverse effects to work.

+  o Added support for multiple channels in .dat files.

+    (1366634) tomchristie

+sox-12.17.9

+-----------

+  o Updates to compile under VC6. Jimen Ching

+  o Declare st_signalinfo_t to specifically be signed in case

+    platform does not default ot signed chars.  This

+    is required for NetBSD/powerpc.

+  o When seek()ing in AIFF, SMP, and WAV handlers, remaining samples were

+    incorrectly computed based on bytes and not samples.  Jukka

+  o Changed noisered effect to just warn during clipping instead

+    of aborting.  Ian Turner

+  o Fixed bug were pieces of audio were lost every buffer read

+    when running both -c and -r options together on mono audio.

+    Users probably percieved it as shorter audio files that

+    played with a sped up tempo.

+    Bugfix will also apply to other times when multiple effects

+    are ran on the command line.

+  o Added support for -V option to play/rec scripts.

+  o Fix to silence effect to allow negative periods to be specified

+    (to remove silence from middle of sound file).

+  o Fix swap option handling so that special case of "swap 1 1" will

+    work.

+  o Track length of Ogg Vorbis files on read.

+  o Add support for displaying a status line that tracks progress

+    of read/write routines.  Part of information requires read

+    file handlers to be able to determine file length.

+  o Converted alsa driver to use asoundlib instead of directly

+    talking to kernel driver.  This also means that device names

+    are now the ALSA logical names instead of /dev type names.

+  o Added ALSA support to play/rec scripts.

+  o Added st_open*, st_read, st_write, st_seek, st_close routines

+    to help simplify developer interface to libst.  See libst.3..

+  o Removed st_initformat(), st_copyformat(), and

+    st_checkformat() from library.  If your app used those

+    functions then copy them from 12.17.8 source code

+    directly into your application or update to use new

+    routines.

+  o Force word-alignment on AIFF SSND and APPL chunks on input.

+    Matthew Hodgson.

+  o Add fix to WAV handler to only return data in multiples

+    of sample_size*channels to better handle corrupt files.

+  o Fixed bug where "-4" option didn't work with avg

+    effect (Tom Christie).

+  o Fixed fade's fade-out-length to match man page

+    description as noted by Geoff Kuenning.  This required

+    updates to the sample crossfade scripts.  Also modified fade

+    effect to report when no more samples will be produced to

+    prevent unneeded reading of whole file.

+  o Allow aborting SoX with SIGTERM, along with previous SIGINT.

+    Norman Ramsey.

+sox-12.17.8

+-----------

+  o noisered effect had compile problems with some compilers.

+  o "-x" option was being ignored since 12.17.7.

+  o Stuart Brady added support for reading and writing RIFX files (big

+    endian RIFF/WAV files).  Also added support for auto detecting

+    DEC-style ".sd\0" files.

+  o Gene Mar found typo in polyphase nuttall calculation.

+  o SMP buffer overflow (detected by gcc 4.0).  Reported by Marcus Meissner

+    and Matthias Saou.

+  o Fixed URL in manpage to resample overviews.

+  o Fixed WAV handler so that it didn't think WAV chunks with max size

+    were invalid chunks.  This allows WAV's to be used in pipes since

+    they have to default to max size.

+  o WAV files with alaw or ulaw data don't need extended format chunks.

+    (Lars Immisch)

+  o In AIFF files, fixed problem were short comments should cause

+    AIFF handler to get confused and become misaligned.

+sox-12.17.7

+-----------

+  o Christian Weisgerber sent patches to man page fixes

+    and patches for sunaudio driver on openbsd.

+  o Default volume for soxmix wrongly set to 0 instead

+    of 1/#_input_files (float rounding error).

+  o Update to ALSA driver to do a better job of detecting

+    unsupported sample rate/size/encoding and change to

+    a supported one.

+  o Fix bug in alsa writing were last last partial buffer

+    wasn't being flushed.

+  o Guentcho Skordev pointed out ogg vorbis files were using

+    the same value for serial numbers each time.

+  o Changed sox to only read the exact size of a WAV data chunk

+    if cooledit IFF LIST chunk is found at the end of the file.

+    Normally, this isn't done to allow reading > 2gig WAV files.

+  o Modified configure to detect cygwin compiler after detecting

+    gcc compiler (fixes some default CFLAGS options).

+  o Added explicit rule for compile *.o from *.c so that

+    CPPFLAGS is always referenced.  Not all platform's default

+    rule includes CPPFLAGS (FreeBSD).

+  o Under linux, add include path to /lib/modules/* so that ALSA

+    include files can be auto detected.

+  o Ian Turner added an effect to remove noise from an audio

+    file by first profiling silent periods of the audio

+    to determine what the noise is (like background hiss on

+    cassette tapes).

+sox-12.17.6

+-----------

+  o Changed comment code to always use copies of strings to

+    fix bug in WAV handlering freeing argv[] memory.

+  o Use calloc() to create ft_t structures so that all

+    memory is initialized before being referenced.

+  o Fixed VOC EOF bug were it thought there was an extra

+    block when there wasn't.

+  o Restructured directory layout so that source code is in

+    a seperate directory.

+  o Modified SoX to accept multiple input files.  Concatenates

+    files together in this case.

+  o Removed map effect so that loops and instr could be removed

+    from effects structures.  This makes effects engine stand

+    alone from the rest of the sox package.

+  o Benedikt Zeyen found a bug in synth effect when generating

+    brown noise that could cause clipping.

+  o David Leverton sent another patch to prevent crashes on

+    amd64's when resampling.

+  o Fixed a bug were MP3 files with large ID3v2 tags could

+    cause SoX to stick in a loop forever.  Now, it will

+    abort on IDv3 tags larger then 100k.  Could still be

+    improved to handle any size.

+  o Changed volume option (-v) so that it tracks the file

+    it was specified.  This means that when specified with

+    the input file, it changes volume before effects engine

+    and when specified with output file, its done after effects

+    engine.

+  o Added crossfade_cat.sh script that will concatenate to

+    audio files and do a crossfade between them.

+  o Fixed bug in fade effect were it was impossible to do a

+    fadeout starting from the beginning of the audio file.

+  o Removed rounding error when changing volume of audio with

+    "-v" option.  This error caused doing a "-v -1.0" twice

+    to not result in the original file.

+  o Fixed a possible overflow in lots of effects were MIN

+    value was treated as -MAX instead of -MAX-1.

+  o Modifed sox so its OK for effects to not process any

+    input or output bytes as long as they return ST_EOF.

+  o When effects output data and reported ST_EOF at the

+    same time, that buffer was discarded as well as

+    data from any chained effect.

+  o Added patch from Eric Benson that attempts to do a seek()

+    if the first effect is trim.  This greatly speeds up

+    processing large files.

+  o Daniel Pouzzner implemented a multi-band compander (using

+    the butterworth filters to split the audio into bands).

+  o Donnie Smith updated the silence effect so that its possible

+    to remove silence from the middle of a sound file by

+    using a negative value for stop_periods.

+  o Changed float routines to only work with normalized values

+    from -1:1.

+  o Modifed .au handler to be able to read and write 32-bit

+    and 64-bit float data.  Only tested reading so far.

+  o WAV with GSM data now always pads data to even number of bytes.

+  o Added support for writing 32-bit audio to AIFF.

+sox-12.17.5

+-----------

+  o Thomas Klausner sent in patches to compile audio drivers under

+    NetBSD.

+  o Rahul Powar pointed out a memory leak in the WAV file handler.

+    It wasn't calling the correct close() function when closing

+    input files.

+  o Modified play.1 man page to not use multiple name lines.  This

+    appears to confuse some conversion programs.  Updated sox.1

+    man page for typo in reverb option.

+  o Andrew Church fixed problem with header of stereo 8SVX files.

+  o Jimen Ching added support to scan over garbage data at the

+    beginning of MP3 files to find valid frames.  This is useful

+    to play WAV and AIFF files that have MP3 data in them until

+    those handlers support it directly.  To play those, force

+    sox to use the mp3 handler with the "-t mp3" option.

+  o Added patch from Ulf Harnhammar to wav handler to prevent

+    buffer overflows.

+  o Added patch from Redhat to allow resample to work on certain 64-bit

+    machines (Sam Varshavchik)

+  o Tony Seebregts added a file handler for headerless Dialogic/OKI ADPCM

+    files (VOX files).

+  o Jan Paul Schmidt added a repeat effect to do loops the brute force way.

+    This is also good for file format that don't support loops as well.

+  o Fix for OSS driver in rate tolerance calcs that were off because

+    of type conversion problems.  Guenter Geiger.

+  o Allow reading sphere files with headers greater then 256 bytes.  Jimen

+    Ching.

+  o Fix for vorbis were comments are displayed in KEY=value format always.

+    Stop printing some info to stdout in case output is a pipe. Guenter

+    Geiger.

+  o J Robert Ray submitted fix for AIFF handler to ignore lowercase

+    chunks that are unknown.

+  o Bugfix for 8-bit voc files.  Jimen Ching

+  o General warning cleanups (cbagwell)

+  o Memory leaks in reading WAV files (Ufuk Kayserilioglu)

+  o Rearrange link order of ogg vorbis libraries so that they

+    can be compiled as static. (Christian Weisgerbr)

+sox-12.17.4

+-----------

+  o Peter Nyhlen fixed a problem with reading Comments in Ogg Vorbis files.

+  o Added install target to allow installing libgsm from main Makefile.

+    Leigh Smith.

+  o Minor updates to sox.c to free unused memory and close all input

+    files during failures.

+  o Pieter Krul added a patch that makes play script look at AUDIODEV

+    environment variable if it exists to find which device to use.

+    This allows scripts to work with Solaris SunRays and is a good idea

+    in general.

+  o Updated config.sub to detect latest supported OS's.

+  o Fabrizio Gennari added support for reading and writing

+    MP3 files using the external libraries libmad and libmp3lame.

+  o Jens Henrik Goebbert sent in several bugfixes for integer overflows

+    in the compand effect.

+  o Dan Dickerman sent in patches for integer overflows in the resample

+    effect.

+  o Jimen Ching sent in a fix for multi-channel sound file processing

+    using the avg effect.

+  o Richards Bannister added patches to clean up prototypes and filter

+    private sizes being to small.

+  o Jimen Ching adds -d option to specify 64bit data size and changed

+    Ulaw/Alaw encoding to default to 8bit data size if not specified.

+  o David Singer pointed out that a MS program creates AIFF files

+    with an invalid length of 0 in its header.  Changed SoX to warn the

+    user but continue instead of aborting since SoX can still read

+    the file just fine.

+  o Bert van Leeuwen added a file handler for Psion record.app used

+    for System/Alarms in some Psion devices.

+  o Richard Bannister sent in a patch to make writing vorbis files

+    work with Vorbis 1.0 libraries.

+  o Fixed configure scripts so that they can be ran with the

+    --with-oss-dsp, --with-alsa, and --with-sun-audio options.

+    Was causing compile time problems.  Reported by Raul Coronado.

+  o Change Ogg Vorbis support to use VBR encoding to match defaults

+    of oggenc based on suggestion from Christian Weisgerber.

+  o Prints error message now when a channel value of -1 is given.

+    Reported by Pierre Fortin.

+  o Fixed bug were memory could be trashed if a input WAV file contained

+    a comment.  Found by Rhys Chard.

+  o Change command line to compile soxmix.o slightly to try and make

+    Forte compiler happy.

+  o Added support for ALSA 0.9 driver. Jimen Ching

+sox-12.17.3

+-----------

+  o Removed check that prevented pan from being invoked when the

+    input and output channels were the same.

+  o Ciaran Anscomb added a flush to sunaudio driver after changing

+    settings.  This is because it can start buffering data as soon

+    as the device is open and the buffered data can be in a

+    wrong format.

+  o trim wasn't accounting for # of channels and was generally broken.

+  o Jeff Bonggren fixed trim bugs were it was failing when triming

+    data that equaled to BUFSIZ.  Also, trim now immediately returns

+    ST_EOF when its done instead of requiring an extra call that

+    returns no data.

+  o auto effect wasn't rewinding the file if the file was less then

+    132 bytes.  Changed auto parsing of header to be incremental

+    instead of reading in a large buffer.

+  o William Plant pointed out a bad pointer access in fade effect's

+    parsing of options.

+  o Ken pointed out a problem were private data was not 8-byte aligned

+    and causing crashes on most RISC CPU's.  Fixed by going back to

+    old style of declaring private data as type "double" which usually

+    forces strictest alignment.

+  o ima_rw was miscompiling on alpha's because of a header ordering

+    problem.

+  o Erik de Castro Lopo pointed out that when writing 16-bit VOC files

+    the headers did not contain the correct length or encoding type.

+  o Seperated st.h into 2 files.  st.h for libst users and st_i.h for

+    internal use.

+  o Added new types used extensively by libst: st_sample_t & st_size_t.

+    This allows for more deterministic behavior on 64-bit machines and

+    also allows sox to possibly work with much larger file sizes.

+  o SoX was some times getting confused and thinking an EOF was an

+    error case when reading audio files.  Removed unneeded aborts

+    when EOF was OK.

+  o Silence effect was broken on stereo files.  Also, made thresholds

+    relative to original bit percision of audio data.  When 16-bit audio

+    is scaled up to 32-bits, a little bit of noise starts to look like a

+    large amplitude of noise.  Also, now using RMS values to smooth out

+    clicks.  RMS rolling window size is 1/10 of sample rate.

+  o Changed Floats into a type of encoding instead of a size of audio data.

+  o Put a flush at the end of OSS driver so that no old data would be

+    left in internal buffers after changing audio format parameters.

+  o Fixed problem were play script wasn't installed correctly if you

+    build from another directory (pointed out by Mike Castle).

+  o Made GSM support internal to libst (no external library required).

+  o Change configure script to enable ulaw/alaw lookup tables and GSM

+    support by default.  Also have Makefile's make use of more configure

+    prefix options to allow for customized installs.

+  o Reverted ulaw/alaw conversion routines back to Sun's versions.

+  o Modified raw file handler to write files in the same generic buffered

+    fashion that was added for reading in 12.17.2.  Seems to have

+    speed up some types of writing.

+  o Reading Ogg Vorbis files could get confused of when EOF was reached.

+  o Added uninstall rules to Makefile.  Added new ststdint.h to define

+    *int*_t typedefs.

+  o Added internal strcasecmp for OS/2.

+  o Added support for swapping "bit" order (MSB becomes LSB) for raw u-law

+    and A-law data.  Some ISDN equipment prefers it this way.  Use -x flag

+    or new .la or .lu file extensions.

+  o Annonymous patch submitted to fix types and spelling problems in

+    various files.  Also, updated VOC files to have u-law and A-law

+    support as well as able to read in VOC files using a pipe.  More

+    examples added to soxexam file.

+sox-12.17.2

+-----------

+  o Daniel Culbert found and fixed a bug in the polyphase effect

+    that occurs on platforms that rand() can return large values.

+    The bug resulted in polyphase resampling an audio file to a

+    different rate then it said it was.

+  o Stan Seibert contributed a handler for Ogg Vorbis files.  It

+    handles all input formats but can only save using default

+    settings.

+  o Darrick Servis has made major cleanups in the code in regards

+    to error conditions.  Helps people using libst.

+  o Darrick Servis has added added optional seek functionality sox.

+    Several formats have been modified to make use of this.

+  o Geoff Kuenning rewrote the average effect into a general-purpose

+    parametric mapping from N channels to M channels.

+  o Geoff Kuenning added an optional delay-time parameter to the compander

+    effect to allow companding to effectively operate based on future

+    knowledge.

+  o Geoff Kuenning Added support to fade and trim effect for specifying time

+    in hh:mm:ss.frac format.

+    Fixed a bug that caused integer overflow when large start/stop times

+    were used.

+  o Geoff Kuenning updated play/rec/soxeffect scripts to handle all effects

+    added since 12.17. Spell-checked soxexam.1 file.

+  o Jimen Ching updated ALSA configure support to auto-detect 4.x or 5.x API

+    and compile correctly under those two.  All other versions are unsupported.

+  o Merged in the NetBSD package changes into CVS finally.

+  o Removed broken support for non-ANSI compilers.

+  o Makefile now places the correct path to SoX in the play/rec scripts

+    based on configuration script values.

+  o Alexander Pevzner provided a fix for OSS driver for sound being

+    dropped under heavy CPU loads.  Moved GETBLKSIZE operation

+    until after setting up the format (SBLive! was modify the block size

+    after changing formats).

+  o With help from David Blythe, updated OSS drivers to use newer format

+    interface.  OSS driver will now attempt to detect a valid endian type

+    to use with sound card.

+  o Carsten Borchardt pointed out a bug in lowp filter.  Added new

+    nul file handler that reads and writes from/to nothing.

+    Also added new synth effect that creates sounds using a simple

+    synthesizer.  Created a testcd.sh that uses two new features

+    to create a test sound CD for testing audio equipment.

+  o Ben Last added a new program that uses libst and will merge two

+    seperate audio files into a single file with multiple channels.

+    This was merged into the standard sox.c file by cbagwell.

+  o Andreas Menke fixed some problems with the speed effect and

+    how effects were drained.  Also improved the usage of printf()'s

+    to use stderr.

+  o Corrected AU header length value when comments were less than

+    4 bytes.

+  o Added support for reading non-standard bit size data from AIFF files.

+  o Ignore unmatched MARK/INSTR chunks in AIFF files now instead of quiting.

+  o Fixed ALAW encoding bug in .au files as pointed out by Bruce Forsberg.

+  o Unified the raw reading functions.  Probably slightly faster for

+    most datatypes but was done to fix recording from the OSS driver.

+    Control-C stopped working somewhere during the 12.17 series.

+  o Ford Prefect added a dcshift which can shift the midline amplitude

+    towards the true center.  This will allow for a greater range

+    of volume adjustments without clipping audio data.

+  o Heikki Leinonen submitted a silence effect that will trim off

+    silence from the beginning of a file.  cbagwell made some modifications

+    to trim off front and back as well as some other tweaks.

+  o Made the "auto" effect the default file handler for input files.

+    Also have auto handler now use file extensions if it can't figure

+    it out.

+sox-12.17.1

+-----------

+  o Andreas Kies fixed a bug were we were not detecting correctly

+    if an output file was seekable.

+  o Fixed a bug in the mask effect introduced in 12.17.  If the libc

+    version of rand() returned more then 15-bit values then it would

+    trash your data.  Reported by Friedhel Mehnert.

+  o Added a new fade in/out effect from Ari Moisio.

+  o AIFF files now ignore a MARK chunk if the loop type is NoLoop (0).

+  o Fixed bug were it was impossible to output ADPCM data in wav files.

+  o Fixed bug were rate had to be specified for sphere files (fix from

+    Antti Honkela).

+  o Added small work around to let compile with cygwin's gcc 95.2

+    which also now allows to compile with GSM support under windows.

+  o Removed accessing of sound devices in tests for sound support and

+    instead just look for needed header files.  This allows the sound

+    support to be detected even if the device is currently busy or when

+    compiled on a box that doesn't have a sound card but the OS supports

+    it (which is the enviornment of most distributions creating new

+    binaries).

+  o Added support to partially handle AIFC files but only uncompressed

+    versions.  This should allow people to work with raw CD audio data

+    on Mac OSX and also gives a basis for adding future support for

+    things like ADPCM processing.

+  o Added new "earwax" effect from Edward Beingessner.  It is meant to

+    be used for CD audio played through headphones.  It will move the

+    sound stage from left/right to in front of you.

+  o Trim effect did not compute locations as was documented in the

+    man pages.  Changed effect so that it computed the time the

+    same way that the fade effect does.

+sox-12.17

+---------

+  o Sox can now read and write w98 compatible gsm .wav files,

+    if compiled properly with libgsm.  Thanks go to Stuart

+    Daines <sjd.u-net.com> for the gsm-wav patches.

+    This is new, and relatively untested. See -g format option.

+  o Sox can now write IMA_ADPCM and ADPCM compressed .wav,

+    this is new, and relatively untested. See -i and -a format

+    options in manpage.

+  o General changes to wav.c for writing additional wav formats.

+    Reading wave headers: more consistency checks.

+    Writing wave headers: fixes for w98.

+  o Speedups to adpcm read routines, new codex versions are

+    now in ima_rw.c and adpcm.c.

+  o Speedups for raw.c, especially for gcc with glibc.

+  o Fixed a segfault problem with ulaw/alaw conversion, where

+    an out-of-range index into the tables could occur.

+  o More detailed output from the stat effect.

+  o Continued rewrite of resample.c, now it is almost as

+    fast with floating arithmetic as the old (buggy) version

+    was with 16-bit integer arithmetic.  The older version

+    in sox-12.16 shifted frequencies slightly and was less

+    accurate.

+  o Extensive rewrite of polyphas.c, should be faster and use

+    less memory now.  The sox-12.16 polyphase code had some bugs.

+  o New effect 'filter' which is a high-quality DSP lowpass/

+    highpass/bandpass filter using windowed sinc function

+    methods, like polyphase and resample.

+  o Jan Paul Schmidt added new low/high/bandpass and bandlimit

+    filters to sox.  They have much better results then the old

+    versions of low/high/bandpass.  The new effects are all

+    Butterworth filters.

+  o New data file type supported, -sl or extension .sl for

+    signed 32-bit integers.  Some simplification of the raw.c

+    source.

+  o Some test programs and scripts in the test directory, for

+    making gnuplot plots of frequency response, error-levels

+    of rate-conversion and filter effects.

+  o Removed sbdsp code.  All modern unixes are support via OSS,

+    ALSA, or sun audio device interfaces.

+  o Added AVR handler from Jan Paul Schmidt.

+  o SoX now waits until the last possible moment before opening

+    the output file.  This will allow all input and effect options

+    to be parsed for errors and abort before overwriting any file.

+  o SoX will no longer write to files that exists.  This will keep

+    it from deleting files when a user mistakenly types "sox *.wav".

+  o Added new compander effect from Nick Bailey.  Nice general purpose

+    filter.

+  o Under Solaris, SoX now checks hardware ability to play stereo/PCM

+    and forces output data to match.  Sorry, no SunOS support.  I don't

+    have access to one any more.

+  o Fixed array overrun bug in rate effect as pointed out by Ian

+    Donaldson.

+  o Fixed clip24() range as pointed out by Ted Powell.

+  o Fixed possible segfault in echos effect, as pointed out by Zinx

+    Verituse.

+  o Moved most documentation to new "soxexam.1" manual page so that

+    all users on a unix system will have access to important information.

+    This means no more TIPS, CHEATS, or CHEATS.eft files.

+  o Richard Kent fixed a byte alignment problem in aiff comment code.

+  o Loring Holden added support to create missing directories on install

+    and support for installs from outside the source directory.

+  o Fabien COELHO added a pan and volume effect.

+  o Fabien COELHO added a speed effect to sox (like speeding up a tape

+    machine).  Also added pitch which changes pitch without effecting

+    duration and stretch which stretch time without effecting pitch.

+  o Leigh Smith updated aiff support to use the COMT check when writing

+    comments instead of the ANNO.  It is the prefered method from Apple

+    and newer programs are starting to require it.  Also fixed some bugs

+    in how we compute the length of various chunks in output files.

+  o Changed the default block alignement for IMA ADPCM WAV files to use

+    256 which is what windows programs use.  Badly written readers expect

+    256.

+  o Matthias Nutt helped add support for specifying multiple effects

+    to SoX on the command line.

+  o Curt Zirzow added a trim effect to trim off audio data.

+  o Updated ALSA driver to support new interface. Jimen Ching

+sox-12.16

+---------

+  o Changed raw data functions to perform I/O operations using block reads.

+    Should improve speeds greatly, especially when filesize is in megs.

+    Got code ready to tweak speed more which also forced me to clean up

+    Endian test code.

+  o Fixed a bug in .au's handling of G.723.  It wasn't using the correct

+    number of bits.  Added A-law support to .au.

+  o Quoted $filename in play/rec scripts so that files with spaces in

+    their names can be given.

+  o Old OS/2 support didn't work.  Replaced with known working EMX

+    GCC compatible code.

+  o ADPCM WAV files were defaulting to 8-bit outputs and thus losing

+    some persision.  Now defaults to 16-bit signed uncompressed data.

+  o Fixed a couple cross-platform compiler issues.

+  o Jimen Ching has added support for "configure" in to SOX.  Finally,

+    a good solution to cross-platform compiling!

+  o Jimen Ching has added native support for the ALSA driver to play

+    and record audio from. (jching@flex.com)

+  o Minor correction for -r example in manual page.

+  o Renamed sox.sh to soxeffect and rewrote.  Symbolic links can be made

+    from this file to the name of a sox effect.  It will then run that

+    effect on STDIN and output the results to STDOUT.

+  o Fixed up some makefiles and 16-bit support from patches sent by

+    Mark Morgan Lloyd (markMLl.in@telemetry.co.uk).  Also added some

+    nice DOS test bat files from him as well.

+  o Cleaned up some more cross-platform compile problems.  In the process

+    got it working with Turbo C again, kinda.  It still locks DOS up at times.

+  o Made AIFF handler work with invalid headers that some programs generate.

+    Also fix an Endian bug thats been there for quite a long time (when

+    ran on Intel machines).  Made comment lengths even length to make

+    most MacOS programs happy.  cbagwell

+  o Resample function was updated by Andreas Wilde

+    (andreas@eakaw2.et.tu-dresden.de) to fix problem were freqs. were

+    off by a factor of 2.

+  o Added an effect that swaps stereo channels.  cbagwell

+  o Combined play and rec scripts to a single program to ease mantaince.

+    Also added GNU style long-options (--help).  Careful, some options have

+    change (but more logical).

+  o Fixed a very old silly bug were low/high/bandpass filters would

+    add some trash data to the end of the sound file.

+  o "avg" effect wouldn't give error message when you tried to average

+    x number of channels in to the same number of channels.

+  o Fixed core dump when writting AIFF files with no comments.

+    (Olaf Pueschel)

+sox-12.15

+---------

+  o Juergen Mueller moved Sox forward quite a bit by adding all the

+    most commonly known "Guitar Effects".  He enhanced echo support,

+    added chorus, flanger, and reverb effects.  He also wrote a very

+    handy CHEAT.eft file for using various effects.

+  o Incorporated Yamaha TX-16W sampler file support provided by

+    Rob Talley (rob@aii.com) and Mark Lakata (lakata@physics.berkeley.edu).

+  o Fixed a small bug in hcom compression, dependent on sign

+    extension.  Leigh Smith (leigh@psychokiller.dialix.oz.au).

+  o sox -h now prints out the file formats and effects supported.

+    Leigh Smith and Chris Bagwell.

+  o smp transfers comments more completely.  Leigh Smith.

+  o aiff manages markers and loops correctly and produces more

+    verbose output.  Leigh Smith.

+  o Added polyphase resampler (kb@ece.cmu.edu).  This adds a slightly

+    different resampling algorithm to the mix.

+  o Michael Brown (mjb@pootle.demon.co.uk) sent a patch to stop crashes

+    from happening when reading mono MS ADPCM files.

+  o Fabrice Bellard has added a less buggy 'rate' conversion.  I've left

+    the old rate code included but if all goes well this will become

+    the new 'rate'.  Please test and let me know how it works.  Resample

+    effect needs to be reworked now.

+  o Heiko Eissfeldt: Implemented a simple deemphasis effect for

+    certain audio cd samples.

+  o Matija Nalis (mnalis@public.srce.hr) sent a patch to fix volume adjustment

+    (-v) option of sox.

+  o Fixed typo in optimazation flag in unix makefile, as pointed out by

+    Manoj Kasichainula (manojk@io.com).

+  o Fixed missing ';;' in play script. cbagwell

+  o Fixed bug in determining length of IMA and MS ADPCM WAVE files. cbagwell

+  o Fixed bug in how stereo effects were drained which fixed the

+    "reverse" effect from only saving half of stereo files. cbagwell

+  o Can use "-e" without an effect again.

+  o Added -g and -a options for new style support of GSM and ADPCM.  Added

+    error checking to various formats to avoid allowing these types.

+sox-12.14

+---------

+  o Bumped major version number up and shortened name.  The shorter name

+    should help the various distributions using this package.

+  o Added support for MS ADPCM and IMA (or DVI) ADPCM for .wav files.

+    Thanks to Mark Podlipec's xanim for this code (podlipec@ici.net).

+  o Change Lance Norskog's email address to thinman@meer.net.  The old

+    one was bouncing.

+  o Added path string to play and rec strings so that it could be run by

+    users without complete paths setup (i.e. Ran by "rc" files during bootup

+    or shutdown)

+  o Fixed -e option from Richard Guenther

+      (richard.guenther@student.uni-tuebingen.de) and fixed a small bug

+    in stat.

+  o Fixed a bug in the mask effect for ULAW/ALAW files.

+  o Fixed a bug in cdr output files that appended trash to end of file.

+  o Guenter Geiger (geiger@iem.mhsg.ac.at) made a rather large patch to

+    allow sox to work on 64-bit alphas.  It was done the easiest meathod

+    by changing all long declarations to use a macro that knows to

+    make it 32-bits.  Want to port to another 64-bit-but-not-alpha

+    machine?  Grep for "alpha" to see changes.  There are most likely

+    several bugs left for alphas.  Guenter is also supporting this

+    package for the Debian distribution.

+  o Did some major code cleanups to clear out some warning messages

+    during compile.  This is to clear up problems I'm finding under

+    both alpha and dos.  Some warning messages are actually useful

+    now (pointing out possible data loss).  Hopefully, I didn't

+    break anything.

+  o Code clean up allows me to finally compile code under Turbo C

+    again.  Too bad the EXE gets a currupted stack somewhere and locks

+    up the system.  Anyone want to try it with Borland C for me?

+    If you get a working EXE I would like to start distributing a DOS

+    package like there used to be.

+  o Speaking of cleanups, anyone want to help cleanup the makefiles for

+    various platforms?  They are quite outdated right now and it is

+    very obvious that Sox hasn't been able to compile under all the

+    platforms it once did for several releases.  Please send in

+    the cleaned-up makefile versions along with what programs you

+    used to compile it with.

+  o There is a known bug in hcom's compress() function.  It is allocating

+    memory that can't be free'd under some OS's.  It causes a core dump.

+sox-11gamma-cb3

+---------------

+This release of sox is mainly a bugfix release.  The following things

+have changed:

+  o  Documentation has been updated when it was obviously wrong.

+     Much more work could be done.  Man pages were updated to

+     work correctly on Solaris and add some missing info.

+  o  Several people sent me patches to fix compiling on Solaris

+     as well as fix a few bugs.

+  o  Change USS driver's name to OSS.  Man, does that driver

+     like to change names!  This could cause problems if you

+     have made your own custom play and rec scripts.

+  o  Updated my email address.  Sorry if I haven't responded to

+     any emails as I no longer have access to my old address.

+     Please use cbagwell@sprynet.com.

+  o  Fixed unix test scripts so that they worked again.

+  o  Fixed endian bug in psion .wve code.

+  o  Replaced outdated voc info file with detailed format info

+     inside voc code.

+  o  Added new sound format, cvsd (Continuously Variable Slope Delta)

+     from Thomas Sailer (sailer@ife.ee.ethz.ch).

+sox-11gamma-cb2

+---------------

+This release of sox is based on the latest gamma version released

+plus some patches I've made to support the following new features:

+I would like to thank everyone that wrote me about the long

+standing bug in Sox that could DELETE your /dev/* file if the

+program was aborted for reason such as invalid audio file.  Special

+thanks for Bryan Franklin for sending in a patch when I was

+to busy to even look for it.

+  o  Better play support for 8-bit stereo voc files.  New support

+     for outputing both 8-bit and 16-bit stereo voc files.

+  o  Built-in support for playing and recording from Linux /dev/dsp.

+     This is a re-write and seperate module from the previous

+     support included inside the sbdsp module.  Also fixes a buffer

+     size bug that showed up when using newer versions of OSS.

+     This driver will work with OSS (and older versions called USS, TASD

+     and Voxware).

+  o  Support for audio playing and recording with SunOS /dev/audio.

+  o  Fixes a bug were /dev/audio or /dev/dsp could be deleted

+     when playing an invalid format audio file.

+  o  Expanded options for play and rec scripts.  You can now specify

+     sox effects after the filename and hear them in real time.

+     Please be sure that an older version of sox is not in your path

+     because these script will possibly find it first and

+     incorrectly use it.

+  o  Setting play/record volume still requires an external program.

+     If you have one a command line program to do this (such as

+     "mixer" for Linux) then you will want to edit the play and rec

+     to use this.  The current support for it is only in example

+     form of how it can be done.

-Change History

---------------

-This file contains a list of all changes starting after the release of

-sox-11gamma.

-sox-12.18.3

------------

-  o Fix to pay attention when starting of effects fails.

-    (Reuben Thomas)

-  o Fixed a bug introduced in 12.18.2 that stopped the draining

-    of effects from occuring.  This had stopped the reverse effect,

-    among others, from working.  (Reuben Thomas)

-  o Add FLAC support (robs@users.sf.net)

-  o Allow encoding quality to be specified (works for Ogg too, but not

-    MP3).

-  o Visualisation of various filters' frequency response via Octave.

-    (robs@users.sf.net)

-  o Allow the rate and number of channels of .au files to be overridden

-    by command-line arguments. (robs@users.sf.net)

-  o More and better self-tests. (robs@users.sf.net)

-  o Support Maxis's XA format. (Dwayne C. Litzenberger)

-  o Add equalizer effect (Pascal Giard)

-  o Fix rounding error when reading command-line time

-    parameters. (robs)

-  o Allow command-line time parameters of < 1 sec to omit the

-    leading 0. (robs)

-  o Fix wav file handler discarding the last PCM sample in certain

-    circumstances. (robs)

-  o Add support for 24-bit PCM raw, wav (WAVE_FORMAT_EXTENSIBLE) [FR# 801015],

-    aiff, & flac files. (robs)

-  o Added alias -1 (for -b), -2 (for -w), -4 (for -l), -8 (for -d). (robs)

-  o Remove old, optional rate change and alaw/ulaw conversion code.

-    (Reuben Thomas)

-  o Make sox and soxmix a single binary.  (Reuben Thomas)

-  o Consistent (and hopefully complete) clipping detection and

-    reporting.  (robs)

-  o Add AIFF-C output support.  (shashimoto)

-  o -V now gives only user-relevant messages, use -V -V to get

-    developer-relevant messages.  (robs)

-  o Old and new rate code removed; the "rate" effect is implemented

-    for backwards compatibility by "resample".

-  o Preview mode now removed, as all it did was use rate rather than

-    resample, and rate has been removed.

-  o Improved synth usage (by introducing -n option) and improved synth

-    entry in the man-page.  (robs)

-  o Documented the butterworth filter effects.  (robs)

-sox-12.18.2

------------

-  o Adding in Debian's disk full fix (#313206).

-  o Finally got rid of reference to cleanup() function in

-    library.  Applications are now required to detect

-    all failures from return codes and cleanup as they

-    want.

-  o Changed how list of formats and effects are stored internally.

-    Effects libst users only. Dirk

-  o Store effects usage so that its accessable by applications.

-    Dirk

-  o Modify the synth effect to not use SIGINT to stop processing

-    and instead return ST_EOF.  This allows exact acount of

-    samples to be written out instead of an approximate amount.

-  o Fix hangup when attempting to write stereo MP3 files.

-    (1512218) Kendrick Shaw

-  o Deemp effect would lose stereo sepeartion. (1479249)

-  o Adding cross-platform support for getopt_long

-  o Make help screens print much more information and add

-    new --help-effect option.  (Originally from Dirk).

-  o Add support for using an external gsm library instead of

-    just the internal one.  Vladimir Nadvornik

-  o Updates to nul file handler to prevent crashes during output.

-    Martin Panter (1482869)

-sox-12.18.1

-------------

-  o The "filter" effect could go into infinite drain mode.  Now

-    only drain 1 buffer.  noisered as well.

-  o SoX was ignoring user aborts (ctrl-c) if it occured during

-    effect drain operations.  This was bad if effects had

-    bugs and stuck in infinite loop.

-  o Stop SoX from crashing when file type could not be auto

-    determined (1417776).

-  o Output filenames with multiple '.' confused SoX.  (1417776)

-    Christian Hammer

-  o Moved to a common set of CLIP routines.  This fixed clipping

-    bugs in noisered and mcompand.

-  o Stop SoX from crashing on sphere files that contain large text

-    strings.  (1430025) Ulf Hamhammar

-  o Fix some overflow crashes in aiff handler. (1430024)  Ulf Hamhammar.

-  o Under windows, set piped input/output to binary mode (1417794). Martin

-    Panter

-  o Fixed broken internal version of strdup().  (1417790) Marty

-  o Stop infinite loop when reading MP3's with a tag size of

-    exactly 8192 bytes.  (1417511) Hans Fugal

-  o Fix typo in stlib.dsp for loading in Visual Studio 6.

-  o Fixed problems in silence effect related to removing multiple

-    periods of silence from the middle of the sound file.

-  o Reduced the window size greatly on the silence effect to

-    prevent leaving in silence that looked like noise still based

-    on RMS values.

-  o Prevent infinite loop in pitch effect from uninitialize variable.

-    Frank Heckenbach

-  o Prevent crashes when printing error mesages (1447239)

-  o Added makefile and support files to compile using Open Watcom

-    compiler.  (1417798) Marty

-  o Stop calling flow() on effects that returned EOF during drain().  Allows

-    two back-to-back reverse effects to work.

-  o Added support for multiple channels in .dat files.

-    (1366634) tomchristie

-sox-12.17.9

------------

-  o Updates to compile under VC6. Jimen Ching

-  o Declare st_signalinfo_t to specifically be signed in case

-    platform does not default ot signed chars.  This

-    is required for NetBSD/powerpc.

-  o When seek()ing in AIFF, SMP, and WAV handlers, remaining samples were

-    incorrectly computed based on bytes and not samples.  Jukka

-  o Changed noisered effect to just warn during clipping instead

-    of aborting.  Ian Turner

-  o Fixed bug were pieces of audio were lost every buffer read

-    when running both -c and -r options together on mono audio.

-    Users probably percieved it as shorter audio files that

-    played with a sped up tempo.

-    Bugfix will also apply to other times when multiple effects

-    are ran on the command line.

-  o Added support for -V option to play/rec scripts.

-  o Fix to silence effect to allow negative periods to be specified

-    (to remove silence from middle of sound file).

-  o Fix swap option handling so that special case of "swap 1 1" will

-    work.

-  o Track length of Ogg Vorbis files on read.

-  o Add support for displaying a status line that tracks progress

-    of read/write routines.  Part of information requires read

-    file handlers to be able to determine file length.

-  o Converted alsa driver to use asoundlib instead of directly

-    talking to kernel driver.  This also means that device names

-    are now the ALSA logical names instead of /dev type names.

-  o Added ALSA support to play/rec scripts.

-  o Added st_open*, st_read, st_write, st_seek, st_close routines

-    to help simplify developer interface to libst.  See libst.3..

-  o Removed st_initformat(), st_copyformat(), and

-    st_checkformat() from library.  If your app used those

-    functions then copy them from 12.17.8 source code

-    directly into your application or update to use new

-    routines.

-  o Force word-alignment on AIFF SSND and APPL chunks on input.

-    Matthew Hodgson.

-  o Add fix to WAV handler to only return data in multiples

-    of sample_size*channels to better handle corrupt files.

-  o Fixed bug where "-4" option didn't work with avg

-    effect (Tom Christie).

-  o Fixed fade's fade-out-length to match man page

-    description as noted by Geoff Kuenning.  This required

-    updates to the sample crossfade scripts.  Also modified fade

-    effect to report when no more samples will be produced to

-    prevent unneeded reading of whole file.

-  o Allow aborting SoX with SIGTERM, along with previous SIGINT.

-    Norman Ramsey.

-sox-12.17.8

------------

-  o noisered effect had compile problems with some compilers.

-  o "-x" option was being ignored since 12.17.7.

-  o Stuart Brady added support for reading and writing RIFX files (big

-    endian RIFF/WAV files).  Also added support for auto detecting

-    DEC-style ".sd\0" files.

-  o Gene Mar found typo in polyphase nuttall calculation.

-  o SMP buffer overflow (detected by gcc 4.0).  Reported by Marcus Meissner

-    and Matthias Saou.

-  o Fixed URL in manpage to resample overviews.

-  o Fixed WAV handler so that it didn't think WAV chunks with max size

-    were invalid chunks.  This allows WAV's to be used in pipes since

-    they have to default to max size.

-  o WAV files with alaw or ulaw data don't need extended format chunks.

-    (Lars Immisch)

-  o In AIFF files, fixed problem were short comments should cause

-    AIFF handler to get confused and become misaligned.

-sox-12.17.7

------------

-  o Christian Weisgerber sent patches to man page fixes

-    and patches for sunaudio driver on openbsd.

-  o Default volume for soxmix wrongly set to 0 instead

-    of 1/#_input_files (float rounding error).

-  o Update to ALSA driver to do a better job of detecting

-    unsupported sample rate/size/encoding and change to

-    a supported one.

-  o Fix bug in alsa writing were last last partial buffer

-    wasn't being flushed.

-  o Guentcho Skordev pointed out ogg vorbis files were using

-    the same value for serial numbers each time.

-  o Changed sox to only read the exact size of a WAV data chunk

-    if cooledit IFF LIST chunk is found at the end of the file.

-    Normally, this isn't done to allow reading > 2gig WAV files.

-  o Modified configure to detect cygwin compiler after detecting

-    gcc compiler (fixes some default CFLAGS options).

-  o Added explicit rule for compile *.o from *.c so that

-    CPPFLAGS is always referenced.  Not all platform's default

-    rule includes CPPFLAGS (FreeBSD).

-  o Under linux, add include path to /lib/modules/* so that ALSA

-    include files can be auto detected.

-  o Ian Turner added an effect to remove noise from an audio

-    file by first profiling silent periods of the audio

-    to determine what the noise is (like background hiss on

-    cassette tapes).

-sox-12.17.6

------------

-  o Changed comment code to always use copies of strings to

-    fix bug in WAV handlering freeing argv[] memory.

-  o Use calloc() to create ft_t structures so that all

-    memory is initialized before being referenced.

-  o Fixed VOC EOF bug were it thought there was an extra

-    block when there wasn't.

-  o Restructured directory layout so that source code is in

-    a seperate directory.

-  o Modified SoX to accept multiple input files.  Concatenates

-    files together in this case.

-  o Removed map effect so that loops and instr could be removed

-    from effects structures.  This makes effects engine stand

-    alone from the rest of the sox package.

-  o Benedikt Zeyen found a bug in synth effect when generating

-    brown noise that could cause clipping.

-  o David Leverton sent another patch to prevent crashes on

-    amd64's when resampling.

-  o Fixed a bug were MP3 files with large ID3v2 tags could

-    cause SoX to stick in a loop forever.  Now, it will

-    abort on IDv3 tags larger then 100k.  Could still be

-    improved to handle any size.

-  o Changed volume option (-v) so that it tracks the file

-    it was specified.  This means that when specified with

-    the input file, it changes volume before effects engine

-    and when specified with output file, its done after effects

-    engine.

-  o Added crossfade_cat.sh script that will concatenate to

-    audio files and do a crossfade between them.

-  o Fixed bug in fade effect were it was impossible to do a

-    fadeout starting from the beginning of the audio file.

-  o Removed rounding error when changing volume of audio with

-    "-v" option.  This error caused doing a "-v -1.0" twice

-    to not result in the original file.

-  o Fixed a possible overflow in lots of effects were MIN

-    value was treated as -MAX instead of -MAX-1.

-  o Modifed sox so its OK for effects to not process any

-    input or output bytes as long as they return ST_EOF.

-  o When effects output data and reported ST_EOF at the

-    same time, that buffer was discarded as well as

-    data from any chained effect.

-  o Added patch from Eric Benson that attempts to do a seek()

-    if the first effect is trim.  This greatly speeds up

-    processing large files.

-  o Daniel Pouzzner implemented a multi-band compander (using

-    the butterworth filters to split the audio into bands).

-  o Donnie Smith updated the silence effect so that its possible

-    to remove silence from the middle of a sound file by

-    using a negative value for stop_periods.

-  o Changed float routines to only work with normalized values

-    from -1:1.

-  o Modifed .au handler to be able to read and write 32-bit

-    and 64-bit float data.  Only tested reading so far.

-  o WAV with GSM data now always pads data to even number of bytes.

-  o Added support for writing 32-bit audio to AIFF.

-sox-12.17.5

------------

-  o Thomas Klausner sent in patches to compile audio drivers under

-    NetBSD.

-  o Rahul Powar pointed out a memory leak in the WAV file handler.

-    It wasn't calling the correct close() function when closing

-    input files.

-  o Modified play.1 man page to not use multiple name lines.  This

-    appears to confuse some conversion programs.  Updated sox.1

-    man page for typo in reverb option.

-  o Andrew Church fixed problem with header of stereo 8SVX files.

-  o Jimen Ching added support to scan over garbage data at the

-    beginning of MP3 files to find valid frames.  This is useful

-    to play WAV and AIFF files that have MP3 data in them until

-    those handlers support it directly.  To play those, force

-    sox to use the mp3 handler with the "-t mp3" option.

-  o Added patch from Ulf Harnhammar to wav handler to prevent

-    buffer overflows.

-  o Added patch from Redhat to allow resample to work on certain 64-bit

-    machines (Sam Varshavchik)

-  o Tony Seebregts added a file handler for headerless Dialogic/OKI ADPCM

-    files (VOX files).

-  o Jan Paul Schmidt added a repeat effect to do loops the brute force way.

-    This is also good for file format that don't support loops as well.

-  o Fix for OSS driver in rate tolerance calcs that were off because

-    of type conversion problems.  Guenter Geiger.

-  o Allow reading sphere files with headers greater then 256 bytes.  Jimen

-    Ching.

-  o Fix for vorbis were comments are displayed in KEY=value format always.

-    Stop printing some info to stdout in case output is a pipe. Guenter

-    Geiger.

-  o J Robert Ray submitted fix for AIFF handler to ignore lowercase

-    chunks that are unknown.

-  o Bugfix for 8-bit voc files.  Jimen Ching

-  o General warning cleanups (cbagwell)

-  o Memory leaks in reading WAV files (Ufuk Kayserilioglu)

-  o Rearrange link order of ogg vorbis libraries so that they

-    can be compiled as static. (Christian Weisgerbr)

-sox-12.17.4

------------

-  o Peter Nyhlen fixed a problem with reading Comments in Ogg Vorbis files.

-  o Added install target to allow installing libgsm from main Makefile.

-    Leigh Smith.

-  o Minor updates to sox.c to free unused memory and close all input

-    files during failures.

-  o Pieter Krul added a patch that makes play script look at AUDIODEV

-    environment variable if it exists to find which device to use.

-    This allows scripts to work with Solaris SunRays and is a good idea

-    in general.

-  o Updated config.sub to detect latest supported OS's.

-  o Fabrizio Gennari added support for reading and writing

-    MP3 files using the external libraries libmad and libmp3lame.

-  o Jens Henrik Goebbert sent in several bugfixes for integer overflows

-    in the compand effect.

-  o Dan Dickerman sent in patches for integer overflows in the resample

-    effect.

-  o Jimen Ching sent in a fix for multi-channel sound file processing

-    using the avg effect.

-  o Richards Bannister added patches to clean up prototypes and filter

-    private sizes being to small.

-  o Jimen Ching adds -d option to specify 64bit data size and changed

-    Ulaw/Alaw encoding to default to 8bit data size if not specified.

-  o David Singer pointed out that a MS program creates AIFF files

-    with an invalid length of 0 in its header.  Changed SoX to warn the

-    user but continue instead of aborting since SoX can still read

-    the file just fine.

-  o Bert van Leeuwen added a file handler for Psion record.app used

-    for System/Alarms in some Psion devices.

-  o Richard Bannister sent in a patch to make writing vorbis files

-    work with Vorbis 1.0 libraries.

-  o Fixed configure scripts so that they can be ran with the

-    --with-oss-dsp, --with-alsa, and --with-sun-audio options.

-    Was causing compile time problems.  Reported by Raul Coronado.

-  o Change Ogg Vorbis support to use VBR encoding to match defaults

-    of oggenc based on suggestion from Christian Weisgerber.

-  o Prints error message now when a channel value of -1 is given.

-    Reported by Pierre Fortin.

-  o Fixed bug were memory could be trashed if a input WAV file contained

-    a comment.  Found by Rhys Chard.

-  o Change command line to compile soxmix.o slightly to try and make

-    Forte compiler happy.

-  o Added support for ALSA 0.9 driver. Jimen Ching

-sox-12.17.3

------------

-  o Removed check that prevented pan from being invoked when the

-    input and output channels were the same.

-  o Ciaran Anscomb added a flush to sunaudio driver after changing

-    settings.  This is because it can start buffering data as soon

-    as the device is open and the buffered data can be in a

-    wrong format.

-  o trim wasn't accounting for # of channels and was generally broken.

-  o Jeff Bonggren fixed trim bugs were it was failing when triming

-    data that equaled to BUFSIZ.  Also, trim now immediately returns

-    ST_EOF when its done instead of requiring an extra call that

-    returns no data.

-  o auto effect wasn't rewinding the file if the file was less then

-    132 bytes.  Changed auto parsing of header to be incremental

-    instead of reading in a large buffer.

-  o William Plant pointed out a bad pointer access in fade effect's

-    parsing of options.

-  o Ken pointed out a problem were private data was not 8-byte aligned

-    and causing crashes on most RISC CPU's.  Fixed by going back to

-    old style of declaring private data as type "double" which usually

-    forces strictest alignment.

-  o ima_rw was miscompiling on alpha's because of a header ordering

-    problem.

-  o Erik de Castro Lopo pointed out that when writing 16-bit VOC files

-    the headers did not contain the correct length or encoding type.

-  o Seperated st.h into 2 files.  st.h for libst users and st_i.h for

-    internal use.

-  o Added new types used extensively by libst: st_sample_t & st_size_t.

-    This allows for more deterministic behavior on 64-bit machines and

-    also allows sox to possibly work with much larger file sizes.

-  o SoX was some times getting confused and thinking an EOF was an

-    error case when reading audio files.  Removed unneeded aborts

-    when EOF was OK.

-  o Silence effect was broken on stereo files.  Also, made thresholds

-    relative to original bit percision of audio data.  When 16-bit audio

-    is scaled up to 32-bits, a little bit of noise starts to look like a

-    large amplitude of noise.  Also, now using RMS values to smooth out

-    clicks.  RMS rolling window size is 1/10 of sample rate.

-  o Changed Floats into a type of encoding instead of a size of audio data.

-  o Put a flush at the end of OSS driver so that no old data would be

-    left in internal buffers after changing audio format parameters.

-  o Fixed problem were play script wasn't installed correctly if you

-    build from another directory (pointed out by Mike Castle).

-  o Made GSM support internal to libst (no external library required).

-  o Change configure script to enable ulaw/alaw lookup tables and GSM

-    support by default.  Also have Makefile's make use of more configure

-    prefix options to allow for customized installs.

-  o Reverted ulaw/alaw conversion routines back to Sun's versions.

-  o Modified raw file handler to write files in the same generic buffered

-    fashion that was added for reading in 12.17.2.  Seems to have

-    speed up some types of writing.

-  o Reading Ogg Vorbis files could get confused of when EOF was reached.

-  o Added uninstall rules to Makefile.  Added new ststdint.h to define

-    *int*_t typedefs.

-  o Added internal strcasecmp for OS/2.

-  o Added support for swapping "bit" order (MSB becomes LSB) for raw u-law

-    and A-law data.  Some ISDN equipment prefers it this way.  Use -x flag

-    or new .la or .lu file extensions.

-  o Annonymous patch submitted to fix types and spelling problems in

-    various files.  Also, updated VOC files to have u-law and A-law

-    support as well as able to read in VOC files using a pipe.  More

-    examples added to soxexam file.

-sox-12.17.2

------------

-  o Daniel Culbert found and fixed a bug in the polyphase effect

-    that occurs on platforms that rand() can return large values.

-    The bug resulted in polyphase resampling an audio file to a

-    different rate then it said it was.

-  o Stan Seibert contributed a handler for Ogg Vorbis files.  It

-    handles all input formats but can only save using default

-    settings.

-  o Darrick Servis has made major cleanups in the code in regards

-    to error conditions.  Helps people using libst.

-  o Darrick Servis has added added optional seek functionality sox.

-    Several formats have been modified to make use of this.

-  o Geoff Kuenning rewrote the average effect into a general-purpose

-    parametric mapping from N channels to M channels.

-  o Geoff Kuenning added an optional delay-time parameter to the compander

-    effect to allow companding to effectively operate based on future

-    knowledge.

-  o Geoff Kuenning Added support to fade and trim effect for specifying time

-    in hh:mm:ss.frac format.

-    Fixed a bug that caused integer overflow when large start/stop times

-    were used.

-  o Geoff Kuenning updated play/rec/soxeffect scripts to handle all effects

-    added since 12.17. Spell-checked soxexam.1 file.

-  o Jimen Ching updated ALSA configure support to auto-detect 4.x or 5.x API

-    and compile correctly under those two.  All other versions are unsupported.

-  o Merged in the NetBSD package changes into CVS finally.

-  o Removed broken support for non-ANSI compilers.

-  o Makefile now places the correct path to SoX in the play/rec scripts

-    based on configuration script values.

-  o Alexander Pevzner provided a fix for OSS driver for sound being

-    dropped under heavy CPU loads.  Moved GETBLKSIZE operation

-    until after setting up the format (SBLive! was modify the block size

-    after changing formats).

-  o With help from David Blythe, updated OSS drivers to use newer format

-    interface.  OSS driver will now attempt to detect a valid endian type

-    to use with sound card.

-  o Carsten Borchardt pointed out a bug in lowp filter.  Added new

-    nul file handler that reads and writes from/to nothing.

-    Also added new synth effect that creates sounds using a simple

-    synthesizer.  Created a testcd.sh that uses two new features

-    to create a test sound CD for testing audio equipment.

-  o Ben Last added a new program that uses libst and will merge two

-    seperate audio files into a single file with multiple channels.

-    This was merged into the standard sox.c file by cbagwell.

-  o Andreas Menke fixed some problems with the speed effect and

-    how effects were drained.  Also improved the usage of printf()'s

-    to use stderr.

-  o Corrected AU header length value when comments were less than

-    4 bytes.

-  o Added support for reading non-standard bit size data from AIFF files.

-  o Ignore unmatched MARK/INSTR chunks in AIFF files now instead of quiting.

-  o Fixed ALAW encoding bug in .au files as pointed out by Bruce Forsberg.

-  o Unified the raw reading functions.  Probably slightly faster for

-    most datatypes but was done to fix recording from the OSS driver.

-    Control-C stopped working somewhere during the 12.17 series.

-  o Ford Prefect added a dcshift which can shift the midline amplitude

-    towards the true center.  This will allow for a greater range

-    of volume adjustments without clipping audio data.

-  o Heikki Leinonen submitted a silence effect that will trim off

-    silence from the beginning of a file.  cbagwell made some modifications

-    to trim off front and back as well as some other tweaks.

-  o Made the "auto" effect the default file handler for input files.

-    Also have auto handler now use file extensions if it can't figure

-    it out.

-sox-12.17.1

------------

-  o Andreas Kies fixed a bug were we were not detecting correctly

-    if an output file was seekable.

-  o Fixed a bug in the mask effect introduced in 12.17.  If the libc

-    version of rand() returned more then 15-bit values then it would

-    trash your data.  Reported by Friedhel Mehnert.

-  o Added a new fade in/out effect from Ari Moisio.

-  o AIFF files now ignore a MARK chunk if the loop type is NoLoop (0).

-  o Fixed bug were it was impossible to output ADPCM data in wav files.

-  o Fixed bug were rate had to be specified for sphere files (fix from

-    Antti Honkela).

-  o Added small work around to let compile with cygwin's gcc 95.2

-    which also now allows to compile with GSM support under windows.

-  o Removed accessing of sound devices in tests for sound support and

-    instead just look for needed header files.  This allows the sound

-    support to be detected even if the device is currently busy or when

-    compiled on a box that doesn't have a sound card but the OS supports

-    it (which is the enviornment of most distributions creating new

-    binaries).

-  o Added support to partially handle AIFC files but only uncompressed

-    versions.  This should allow people to work with raw CD audio data

-    on Mac OSX and also gives a basis for adding future support for

-    things like ADPCM processing.

-  o Added new "earwax" effect from Edward Beingessner.  It is meant to

-    be used for CD audio played through headphones.  It will move the

-    sound stage from left/right to in front of you.

-  o Trim effect did not compute locations as was documented in the

-    man pages.  Changed effect so that it computed the time the

-    same way that the fade effect does.

-sox-12.17

----------

-  o Sox can now read and write w98 compatible gsm .wav files,

-    if compiled properly with libgsm.  Thanks go to Stuart

-    Daines <sjd.u-net.com> for the gsm-wav patches.

-    This is new, and relatively untested. See -g format option.

-  o Sox can now write IMA_ADPCM and ADPCM compressed .wav,

-    this is new, and relatively untested. See -i and -a format

-    options in manpage.

-  o General changes to wav.c for writing additional wav formats.

-    Reading wave headers: more consistency checks.

-    Writing wave headers: fixes for w98.

-  o Speedups to adpcm read routines, new codex versions are

-    now in ima_rw.c and adpcm.c.

-  o Speedups for raw.c, especially for gcc with glibc.

-  o Fixed a segfault problem with ulaw/alaw conversion, where

-    an out-of-range index into the tables could occur.

-  o More detailed output from the stat effect.

-  o Continued rewrite of resample.c, now it is almost as

-    fast with floating arithmetic as the old (buggy) version

-    was with 16-bit integer arithmetic.  The older version

-    in sox-12.16 shifted frequencies slightly and was less

-    accurate.

-  o Extensive rewrite of polyphas.c, should be faster and use

-    less memory now.  The sox-12.16 polyphase code had some bugs.

-  o New effect 'filter' which is a high-quality DSP lowpass/

-    highpass/bandpass filter using windowed sinc function

-    methods, like polyphase and resample.

-  o Jan Paul Schmidt added new low/high/bandpass and bandlimit

-    filters to sox.  They have much better results then the old

-    versions of low/high/bandpass.  The new effects are all

-    Butterworth filters.

-  o New data file type supported, -sl or extension .sl for

-    signed 32-bit integers.  Some simplification of the raw.c

-    source.

-  o Some test programs and scripts in the test directory, for

-    making gnuplot plots of frequency response, error-levels

-    of rate-conversion and filter effects.

-  o Removed sbdsp code.  All modern unixes are support via OSS,

-    ALSA, or sun audio device interfaces.

-  o Added AVR handler from Jan Paul Schmidt.

-  o SoX now waits until the last possible moment before opening

-    the output file.  This will allow all input and effect options

-    to be parsed for errors and abort before overwriting any file.

-  o SoX will no longer write to files that exists.  This will keep

-    it from deleting files when a user mistakenly types "sox *.wav".

-  o Added new compander effect from Nick Bailey.  Nice general purpose

-    filter.

-  o Under Solaris, SoX now checks hardware ability to play stereo/PCM

-    and forces output data to match.  Sorry, no SunOS support.  I don't

-    have access to one any more.

-  o Fixed array overrun bug in rate effect as pointed out by Ian

-    Donaldson.

-  o Fixed clip24() range as pointed out by Ted Powell.

-  o Fixed possible segfault in echos effect, as pointed out by Zinx

-    Verituse.

-  o Moved most documentation to new "soxexam.1" manual page so that

-    all users on a unix system will have access to important information.

-    This means no more TIPS, CHEATS, or CHEATS.eft files.

-  o Richard Kent fixed a byte alignment problem in aiff comment code.

-  o Loring Holden added support to create missing directories on install

-    and support for installs from outside the source directory.

-  o Fabien COELHO added a pan and volume effect.

-  o Fabien COELHO added a speed effect to sox (like speeding up a tape

-    machine).  Also added pitch which changes pitch without effecting

-    duration and stretch which stretch time without effecting pitch.

-  o Leigh Smith updated aiff support to use the COMT check when writing

-    comments instead of the ANNO.  It is the prefered method from Apple

-    and newer programs are starting to require it.  Also fixed some bugs

-    in how we compute the length of various chunks in output files.

-  o Changed the default block alignement for IMA ADPCM WAV files to use

-    256 which is what windows programs use.  Badly written readers expect

-    256.

-  o Matthias Nutt helped add support for specifying multiple effects

-    to SoX on the command line.

-  o Curt Zirzow added a trim effect to trim off audio data.

-  o Updated ALSA driver to support new interface. Jimen Ching

-sox-12.16

----------

-  o Changed raw data functions to perform I/O operations using block reads.

-    Should improve speeds greatly, especially when filesize is in megs.

-    Got code ready to tweak speed more which also forced me to clean up

-    Endian test code.

-  o Fixed a bug in .au's handling of G.723.  It wasn't using the correct

-    number of bits.  Added A-law support to .au.

-  o Quoted $filename in play/rec scripts so that files with spaces in

-    their names can be given.

-  o Old OS/2 support didn't work.  Replaced with known working EMX

-    GCC compatible code.

-  o ADPCM WAV files were defaulting to 8-bit outputs and thus losing

-    some persision.  Now defaults to 16-bit signed uncompressed data.

-  o Fixed a couple cross-platform compiler issues.

-  o Jimen Ching has added support for "configure" in to SOX.  Finally,

-    a good solution to cross-platform compiling!

-  o Jimen Ching has added native support for the ALSA driver to play

-    and record audio from. (jching@flex.com)

-  o Minor correction for -r example in manual page.

-  o Renamed sox.sh to soxeffect and rewrote.  Symbolic links can be made

-    from this file to the name of a sox effect.  It will then run that

-    effect on STDIN and output the results to STDOUT.

-  o Fixed up some makefiles and 16-bit support from patches sent by

-    Mark Morgan Lloyd (markMLl.in@telemetry.co.uk).  Also added some

-    nice DOS test bat files from him as well.

-  o Cleaned up some more cross-platform compile problems.  In the process

-    got it working with Turbo C again, kinda.  It still locks DOS up at times.

-  o Made AIFF handler work with invalid headers that some programs generate.

-    Also fix an Endian bug thats been there for quite a long time (when

-    ran on Intel machines).  Made comment lengths even length to make

-    most MacOS programs happy.  cbagwell

-  o Resample function was updated by Andreas Wilde

-    (andreas@eakaw2.et.tu-dresden.de) to fix problem were freqs. were

-    off by a factor of 2.

-  o Added an effect that swaps stereo channels.  cbagwell

-  o Combined play and rec scripts to a single program to ease mantaince.

-    Also added GNU style long-options (--help).  Careful, some options have

-    change (but more logical).

-  o Fixed a very old silly bug were low/high/bandpass filters would

-    add some trash data to the end of the sound file.

-  o "avg" effect wouldn't give error message when you tried to average

-    x number of channels in to the same number of channels.

-  o Fixed core dump when writting AIFF files with no comments.

-    (Olaf Pueschel)

-sox-12.15

----------

-  o Juergen Mueller moved Sox forward quite a bit by adding all the

-    most commonly known "Guitar Effects".  He enhanced echo support,

-    added chorus, flanger, and reverb effects.  He also wrote a very

-    handy CHEAT.eft file for using various effects.

-  o Incorporated Yamaha TX-16W sampler file support provided by

-    Rob Talley (rob@aii.com) and Mark Lakata (lakata@physics.berkeley.edu).

-  o Fixed a small bug in hcom compression, dependent on sign

-    extension.  Leigh Smith (leigh@psychokiller.dialix.oz.au).

-  o sox -h now prints out the file formats and effects supported.

-    Leigh Smith and Chris Bagwell.

-  o smp transfers comments more completely.  Leigh Smith.

-  o aiff manages markers and loops correctly and produces more

-    verbose output.  Leigh Smith.

-  o Added polyphase resampler (kb@ece.cmu.edu).  This adds a slightly

-    different resampling algorithm to the mix.

-  o Michael Brown (mjb@pootle.demon.co.uk) sent a patch to stop crashes

-    from happening when reading mono MS ADPCM files.

-  o Fabrice Bellard has added a less buggy 'rate' conversion.  I've left

-    the old rate code included but if all goes well this will become

-    the new 'rate'.  Please test and let me know how it works.  Resample

-    effect needs to be reworked now.

-  o Heiko Eissfeldt: Implemented a simple deemphasis effect for

-    certain audio cd samples.

-  o Matija Nalis (mnalis@public.srce.hr) sent a patch to fix volume adjustment

-    (-v) option of sox.

-  o Fixed typo in optimazation flag in unix makefile, as pointed out by

-    Manoj Kasichainula (manojk@io.com).

-  o Fixed missing ';;' in play script. cbagwell

-  o Fixed bug in determining length of IMA and MS ADPCM WAVE files. cbagwell

-  o Fixed bug in how stereo effects were drained which fixed the

-    "reverse" effect from only saving half of stereo files. cbagwell

-  o Can use "-e" without an effect again.

-  o Added -g and -a options for new style support of GSM and ADPCM.  Added

-    error checking to various formats to avoid allowing these types.

-sox-12.14

----------

-  o Bumped major version number up and shortened name.  The shorter name

-    should help the various distributions using this package.

-  o Added support for MS ADPCM and IMA (or DVI) ADPCM for .wav files.

-    Thanks to Mark Podlipec's xanim for this code (podlipec@ici.net).

-  o Change Lance Norskog's email address to thinman@meer.net.  The old

-    one was bouncing.

-  o Added path string to play and rec strings so that it could be run by

-    users without complete paths setup (i.e. Ran by "rc" files during bootup

-    or shutdown)

-  o Fixed -e option from Richard Guenther

-      (richard.guenther@student.uni-tuebingen.de) and fixed a small bug

-    in stat.

-  o Fixed a bug in the mask effect for ULAW/ALAW files.

-  o Fixed a bug in cdr output files that appended trash to end of file.

-  o Guenter Geiger (geiger@iem.mhsg.ac.at) made a rather large patch to

-    allow sox to work on 64-bit alphas.  It was done the easiest meathod

-    by changing all long declarations to use a macro that knows to

-    make it 32-bits.  Want to port to another 64-bit-but-not-alpha

-    machine?  Grep for "alpha" to see changes.  There are most likely

-    several bugs left for alphas.  Guenter is also supporting this

-    package for the Debian distribution.

-  o Did some major code cleanups to clear out some warning messages

-    during compile.  This is to clear up problems I'm finding under

-    both alpha and dos.  Some warning messages are actually useful

-    now (pointing out possible data loss).  Hopefully, I didn't

-    break anything.

-  o Code clean up allows me to finally compile code under Turbo C

-    again.  Too bad the EXE gets a currupted stack somewhere and locks

-    up the system.  Anyone want to try it with Borland C for me?

-    If you get a working EXE I would like to start distributing a DOS

-    package like there used to be.

-  o Speaking of cleanups, anyone want to help cleanup the makefiles for

-    various platforms?  They are quite outdated right now and it is

-    very obvious that Sox hasn't been able to compile under all the

-    platforms it once did for several releases.  Please send in

-    the cleaned-up makefile versions along with what programs you

-    used to compile it with.

-  o There is a known bug in hcom's compress() function.  It is allocating

-    memory that can't be free'd under some OS's.  It causes a core dump.

-sox-11gamma-cb3

----------------

-This release of sox is mainly a bugfix release.  The following things

-have changed:

-  o  Documentation has been updated when it was obviously wrong.

-     Much more work could be done.  Man pages were updated to

-     work correctly on Solaris and add some missing info.

-  o  Several people sent me patches to fix compiling on Solaris

-     as well as fix a few bugs.

-  o  Change USS driver's name to OSS.  Man, does that driver

-     like to change names!  This could cause problems if you

-     have made your own custom play and rec scripts.

-  o  Updated my email address.  Sorry if I haven't responded to

-     any emails as I no longer have access to my old address.

-     Please use cbagwell@sprynet.com.

-  o  Fixed unix test scripts so that they worked again.

-  o  Fixed endian bug in psion .wve code.

-  o  Replaced outdated voc info file with detailed format info

-     inside voc code.

-  o  Added new sound format, cvsd (Continuously Variable Slope Delta)

-     from Thomas Sailer (sailer@ife.ee.ethz.ch).

-sox-11gamma-cb2

----------------

-This release of sox is based on the latest gamma version released

-plus some patches I've made to support the following new features:

-I would like to thank everyone that wrote me about the long

-standing bug in Sox that could DELETE your /dev/* file if the

-program was aborted for reason such as invalid audio file.  Special

-thanks for Bryan Franklin for sending in a patch when I was

-to busy to even look for it.

-  o  Better play support for 8-bit stereo voc files.  New support

-     for outputing both 8-bit and 16-bit stereo voc files.

-  o  Built-in support for playing and recording from Linux /dev/dsp.

-     This is a re-write and seperate module from the previous

-     support included inside the sbdsp module.  Also fixes a buffer

-     size bug that showed up when using newer versions of OSS.

-     This driver will work with OSS (and older versions called USS, TASD

-     and Voxware).

-  o  Support for audio playing and recording with SunOS /dev/audio.

-  o  Fixes a bug were /dev/audio or /dev/dsp could be deleted

-     when playing an invalid format audio file.

-  o  Expanded options for play and rec scripts.  You can now specify

-     sox effects after the filename and hear them in real time.

-     Please be sure that an older version of sox is not in your path

-     because these script will possibly find it first and

-     incorrectly use it.

-  o  Setting play/record volume still requires an external program.

-     If you have one a command line program to do this (such as

-     "mixer" for Linux) then you will want to edit the play and rec

-     to use this.  The current support for it is only in example

-     form of how it can be done.
