If you want a complete instrument, several such are available.  For a chip
which is preprogrammed to do real-time FFT's, you might try an Austek
A41102 (article in EE Times, 11/28/88)  Article didn't mention Austek's
address, but the article was apparently submitted by "David Taylor
(415)960-1315".  Hope this helps.
