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.

Apart from wav shntool supports many formats through helper programs.
Please see the manpage for more info.
