Re: [sc-users] a bit off topic...

Your friend should join the music-dsp mailing list, lots of expertise
on that list: http://music.columbia.edu/mailman/listinfo/music-dsp

It's hard to tell what you want to do without a more precise
description. If by "FFT correlation" you mean do a correlation on the
FFT bin amplitudes (to see if the signals have a similar spectral
shape) then yes, that's totally doable in C++.
