In the referenced posting, joe@gistdev.gist.com (Joe Brownlee)
has some sound files which produce only static when converted for
use with Master Juggler.

It sounds like these are compressed sound files. Have a look at
at the data fork of the file with a tool like Fedit Plus--if the first
four bytes are the letters "HCOM", then it's a "Huffman delta" compressed
file.

Somewhere on the net there is the source to a program called SoundPlay,
which includes assembly-language code for doing the decompression.
