One thing to experiment with is the recently available GS source samples.
One of the programs plays back digitized sounds.  For those types of sounds,
the data is simply amplitude with $80 being 0 amplitude [1 is minimum amp &
$FF is max .. 0 tells the generator to shut down.  You have to decide what
sample rate to use.  I don't know what hardware is available for the GS for
actually sampling sounds.  I've used sounds from the Mac (usually created
with MacRecorder) without problems (after I found that 0's should be changed
to 1's in the data).

There is not, as far as I'm aware, any standard format for sound files other
than raw data (which doesn't tell you the sample rate).
