Another method that might work depending on your situation is to
just concatenate all of the audio clips into one long file and
encode that. When the game starts up, you can decompress
it and just play the individual chunks as you need them. You''ll
waste some memory, but that may or may not be a problem.
I don't think this would be easier or harder than Michael's
suggesting. Just a different tack.
