  PICs aren't particularly powerful--they have very limited memory
resources--but, they are *fast*.  For dedicated apps, this speed is
everything.  For something like a quantizer, a PIC should have no problem.
In fact, the tricky part of quantizing is in choosing really good A/D and
D/A subsytem parts so as to keep the error values as small as possible.
