I have a need to perform real time spectrum analysis on an audio signal. A friend said that he had heard about at least one chip that would do this for me without the hassle of programming a DSP system for an FFT or the need to build a filter bank of analog filters. He thought that the chip might have been a ASA-16 (sixteen channels?). Does anybody know anything about this particular chip or any others which will simplify the problem of spectral analysis? Thanks for your help, J.R.

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.
