shntool is a command-line utility to view and/or modify WAVE data
and properties. It runs in several different operating modes, and
supports various lossless audio formats.

shntool is comprised of three parts - its core, mode modules, and
format modules. This helps to make the code easier to maintain, as
well as aid other programmers in developing new functionality. The
distribution archive contains a file named 'modules.howto' that
describes how to create a new mode or format module, for those so
inclined.
