shntool

multi-purpose tool for manipulating and analyzing WAV files
shntool is a multi-purpose WAVE data processing and reporting utility.
File formats are abstracted from its core, so it can process any file
that contains WAVE data, compressed or not - provided there exists a
format module to handle that particular file type.
.
shntool has native support for .wav files. If you want it to work with
other formats, you must have the appropriate helper program installed.
Some of these helper programs - notably for Monkey's Audio, wavpack, LPAC,
OptimFROG - are not (yet) available in Debian.
.
With the helper programs mentioned above, shntool is able to convert files
between all supported formats.
