Well, Paul is right - the .wav format supports all sorts of different
compression methods.
But, in fact, the first 4 bytes of any .wav sample header are always RIFF,
just as the first 4 bytes of our 8svx samples are always FORM.
The compression information (if it is compressed) is found elsewhere in the
header. I can send you the .wav doc if you want it.
But the best solution (I think) would be to get someone with a PC to convert
the sample to an uncompressed 8bit or 16bit .wav for you...
Later...
