SoX 12.17.4 released

SoX is meant to be the Swiss Army Knife of sound processing utils. It can convert audio files to other popular audio file types and also apply sound effects and filters during the conversion. This release adds support for reading and writing MP3 files using the external libraries libmad and libmp3lame; and a number of bugfixes.

I'd like to announce the release of SoX 12.17.4. It is avaliable from http://sox.sourceforge.net/.

The following things have changed since the release of SoX 12.17.3:

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
