There are a multitude of standard file formats in use as well as lots of
non-standard formats.  Some are easy to program with and others can be quite
complex.  Some also have software libraries available which make life easier.

A very good and very comprehensive list of audio file formats is prepared
by Guido van Rossum.  The list is posted regularly to comp.dsp, and
alt.binaries.sounds.misc, amongst others.  It includes information on
sampling rates, hardware, compression techniques, file format defintions,
format conversion, standards, programming hints and lots more.

Try looking at that list first.  I think you'll find several formats which
meet your requirments.
