SoX is a command line utility that can convert various formats of computer audio files in to other formats.  It can also apply various effects to these sound files during the conversion.  As an added bonus, SoX can play and record audio files on several unix style platforms.

Things fixed/added since version 12.17.4:

- Fix memory leak in WAV read handler.
- MP3 reader now attemps to read past unknown data at beginning of file.  Can be used to ignore MP3 data wrapped by a WAV header.
- New support for Dialogic/OKI ADPCM .VOX files
- Allow reading Sphere files with headers greater then 256 bytes.
- Fix in vorbis writing that would print garbage to stdout (corrupted data when used in pipes).
- Fix for stereo headers in 8SVX files.
- Fix buffer overflow issue in WAV handler.
- Fix for compiling on resample on 64-bit machines.
- New repeat effect to repeat audio samples.
- Fix in rate tolerance calculations in OSS driver.
- Change Vorbis comments to start with COMMENT= to match KEYWORD=value standard.
- Fix for writting 8-bit VOC files.
- Modified Makefile to allow sox to be compiled as static binary when Ogg Vorbis is compiled in.
