MP3 yet). (robs)
o Rename -b to -1, -w to -2, -l to -4, -d to -8, and mask to dither.
(robs)
o New options for specifying endianness (and separate options for
nibble & bit reversal) [FR# 1621702]. (robs)

or Q. (robs)
o Dither/mask amount now specifiable. (robs)
o Consistent (and hopefully complete) clipping detection and
reporting. (robs)
o Allow command-line time parameters of < 1 sec to omit the
leading 0. (robs)
o Improved synth usage and improved the synth entry in the man-
page. (robs)
o Higher quality audio speed adjustment; also fixes [1155364]. (robs)
o Replacement flanger effect; also fixes [1393245]. (robs)
o Added silence padding effect. (robs)
o Added ability for noiseprof to use stdout and noisered to use stdin
[FR# 1621694]. (Reuben Thomas)
o vibro effect name deprecated in favour of tremolo; this effect
reimplemented as a special case of synth. (robs)
Other new features:
o Remove soxmix. (Reuben Thomas)
o Preview mode now removed, as all it did was use rate rather than
resample, and rate has been removed.
o -V now gives only user-relevant messages, use -V -V to get
developer-relevant messages. (robs)
o -V output much improved and expanded; now includes display of
(auto-)selected effects. (robs)
o sox man-page overhaul, new soxexam man-page entries. (robs)
o Added command line options for specifying the output file
comment. (robs)
o Added ability to merge e.g. 2 mono files to 1 stereo file
[FR# 1297076]. (robs)
o Removed the restrictions whereby multiple input files had to have
the same data encoding & size, and in most situations where they
had to have the same # of channels, and for play where they had
to have the same sampling-rate. (robs)
o Options to apply replay-gain on input; enabled by default
with `play'. (robs)
o Can now use Ctrl-C to skip to next track when playing multiple
files (e.g. play *.mp3); Ctrl-C twice to exit. (robs)
o Added --interactive option to prompt to overwrite pre-existing
output file. (robs)
o Added large file support. (Reuben Thomas)
Bug fixes:

detected as valid MP3 frames.
o Fix to stop, avoiding a crash, 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 Several effects are now optimised out in situations where they need
do nothing, e.g. changing rate from 8000 to 8000, or changing volume
by 0dB [Bug# 1395781]. (robs)

parameters. (robs)
o Fix nul file hander ignoring other format options if rate
option has not been given. (robs)

o Fix [1160154] VOX to WAV conversion problem. (robs)
o Removed (for output file only) the potentially
problematic -v option. Use the vol effect instead. (robs)
o Improved the accuracy of integer and floating point PCM
conversions. (robs)
o Don't go into a loop on zero-padded WAVs. (Jorge Serna)
o Fix to AIFF writing to avoid writing invalid files in some situations.
(Reuben Thomas)
o Fix compander effect bugs: [1613030] Compand fails to compress
clipping, [1181423] compand with 0 sec attack/release. (robs)
Internal improvements:
o More and better self-tests. (robs)
o Build system overhaul to use the full set of GNU autotools.
(Reuben Thomas)
o Add new getopt1.c to win32 project file.
o Remove old, optional rate change and alaw/ulaw conversion code.
(Reuben Thomas)
o Removed the old internally invoked (but mentioned in the man page)
copy effect. (robs)
sox-12.18.2 2006-09-03
-----------
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 Fix deemph effect would lose stereo separation. (1479249) robs
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 2006-05-07
------------
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.

sox-12.17.9 2005-12-05
-----------
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.
