Change History
--------------
This file contains a list of all changes starting after the release of
sox-11gamma.
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.
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.

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.
