there's fft C library, http://www.fftw.org/

No I probably have to rewrite all my routines to C. I haven't started 
working on FFT at all.

?

FFT = Fast fourier transform

Steeve, thanks for the FFT, I'm really interested. I had only DFT 
running for my modular synth. And maybe iFFT also, I don't remember, 
I hope the sources are still somewhere in deeps of the Internets.

Anton, you asked why i had an FFT implementation...

Because, i made some tests to extract frequencies from wav sounds, 
to be able to play sounds on an old 8bit sound chip.
And also, i wanted to use FFT to make an image compressor.
Geez, so much projects vanished...

someone tried to adapt FFT  on Rebol ?
