The Snack Sound Toolkit is designed to be used with a scripting
language.
Currently it supports Tcl/Tk and Python.
Snack adds commands to play, record, and process sound and supports
in-memory sound objects, file based audio, and streaming audio.
It handles fileformats such as WAV, MP3, AU, AIFF, and CSL.
There are optional packages for NIST/Sphere and Ogg/Vorbis file formats.

Snack is extensible, new commands, filters, and sound file formats can
be added using the Snack C-library. An easy to build example extension
is contained in the source distribution.
Snack also does sound visualization, e.g. waveforms and spectrograms.
The visualization objects update in real-time and can output postscript.

Snack works with Tcl8.0 - Tcl8.4 and python 1.5.2-2.1
Platforms: Linux, Solaris, HP-UX, IRIX, NetBSD, Macintosh, and
Windows 95/98/NT/2K.
