I realize that this is a very basic question, but I did look in the
FAQ and couldn't find the answer, so ...

What is a reference for the format of the Soundfiles?  From the
on-line documentation, I get the impression that data is stored in the
form of 1 byte which is interpretted by something called mulaw.  How
do I find out what all this means?  To be more specific, I would like
to be able to get my hands on data in pure amplitude form, so as to be
able to do FFT work on it.  Like, is there some form of conversion to
16 bit format, and would that do what I want?

Again, I apologize if this is too basic for this group, but I didn't
know where else to ask, and our local "gurus" were not helpful on this.
