Keywords: Format of voice storage?  PCM?

I posted a query about this a while ago, and got a lot of helpful
responses regarding the AT&T method of voice storage for the UNIX-PC.
HOWEVER, I didn't get any information regarding the Macintosh method.
The program I saw and have a voice data file for gave an interface showing
a menu of voice files and a sampling rate, either 11KHz or 22KHz, I think.
I'd like to know the format in which the sound is stored.  Is it linear
PCM?  Or how is it encoded?  Anyone got a clue?  I have the file in
two versions (that may or may not be directly supported by the program) --
one is the raw data, and the other is the data converted to ASCII numbers.
All help and suggestions/conjecture will be appreciated.
