Hello,
FFTW is really fast, but i've had trouble binding to it, so I ripped
the FFT code from Scheme's SLIB. The result is a small program that
displays in pseudo colour the spectrogram of a 16-bit raw audio
file, using Bigarray and Graphics :

BTW, couldn't someone hack FFTW to generate Caml code ? I mean, what's
the point of using C ?
