I should think so. ADPCM compression is pretty poor except where dynamic
range is limited (i.e. telephony).

I believe SOX is compatible with Microsoft's notion of IMA ADPCM (which
may or may not be compatible with anything else).
There's another ADPCM implementation (Jack Jansen's) which, again, may or
may not be compatible with anything else (I don't think it's compatible
with anything from M$). I'll send you source under separate cover.
(Unfortunately, the source I have is at least five years old and I've long
since lost track of where it came from.)
