There's a lot of info about sounds in the mail archives but the short
answers are:

- if you have a lot of sounds, you will probably be better off storing them
externally of the stack since importing them into the stack will require
they all be loaded into memory at once

- in general, voice is more forgiving of compression than other audio such
as music, so you could probably go with 11k, 8bit, mono (note: whatever
sampling/compression you choose must be a common standard -- 11k/22k/44k,
8bit, 16bit -- or Rev will not play the sounds correctly)

- WAV and AIFF will work cross-platform, if that matters

Test!
