  As a matter of fact I designed a sound digitizer for a school project
on my ST.  I designed the circuit (very simple actually, just a A/D converter
and an amplifier) and implemented it on a Douglas prototype board.  I
used wire wrapping and the toal cost for making it was under $30.  However,
the A/D converter I used would be very difficult to obtain.  I got mine
by asking for a sample to be sent out for "an Engineering Project" I was
involved in.  I also wrote software that can sample the converter at up to
64 kHz (it might even go higher but I haven't tried).  The software is GEM
based and allows you to play/edit a number of digitized sounds at once.
If you are interested, I might be cajoled into making it public domain
I also have a LaTeX document with my final report on my project's status, I
would certianly be willing to send this out to those interested.  (Figures
not included, I drew most be hand.)
