Oh, sorry for the misunderstanding. The Mac sound manager will play
digital samples. You pass it pointers to buffers containing the samples.

Read "Inside Macintosh", volume V, p 485+ for more info. The data format
of these buffers are documented there, so you can stuff your waveforms 
directly in as you create them; no need to create SND files.
