A good introduction to all file-format and related questions is pointed to in
the comp.speech FAQ:

When you retrieve the files from ftp.cwi.nl, you'll find a further pointer to
another file on ftp.cwi.nl, "RIFF-format", which contains probably more than
the information you're after! (If you want me to Email it to you, please
There are, however, a number of format conversion utilities around which might
save you some coding: I use a NEXTSTEP interface (GISO) to sox, which seem to
be popular -- maybe someone else could give a pointer to original sources?
