Hi, I am looking for a way to take some audio input from a regular cassette
tape and convert it to some sort of numerical data so that I can put it
into a fast fourier transform. 

If anyone has any ideas on an appropriate interface so that I could get
sampling rate of about 20 data points per second, and only enter the
amplitude of the signal, I would love to hear them.

I'm trying to analyze fourier series on tapes of people, and their volume
as a function of time and conditions.

Thanks for any help,

Tomo  c9c-ae@dorothy.berkeley.edu
