I am interested in any information on chips that would facilitate construction
of an audio-range spectrum analyzer.  The ideal solution would be a single
chip that could be accessed n-times a second and provide a computer a word or
words in which each bit represents a frequency range, and the "on" condition
would represent the signal at that range going above a preset threshold during
the time-slice involved....however, any chip or set of chips that could do
the same for a single frequency range would probably do.

The application, by the way, is a computer-displayed voiceprint...Fourier
Analysis is just too slow.

Thanks.........
