Can someone please tell me what the fastest FFT and iFFT libs are? Maybe one of the ops can ask Stephane once... (sorry for my english).
Thanks!

FFT=Fast Fourier Transform ?
a quick algorithm to compute the Fourier transform (and the find the most important frequencies , probably used in beat matching)
but maybe it was not the question.
(abd maybe it is not the answer ;-)

Yep, that's it! I found the Intel SPL and FFTW, but they seem quite difficult to use... I don't need all those functions. Only the FFT transform and the magnitude, phase and freq extraction. I found some code (www.dspdimension.com, really a great site!) but it's not fast enough...

Oh ! I forgot to ask you...
I've asked Corpse already .... but he's a busy guy: Is it possible to write an algorithm which alters the pitch (instrumental tone) of the sound without modifying the speed/tempo ???
This way when you are making mixes .... not only the speed is matched but also the instrumental tone. But I am sure when if you were to alter something like that .... I assume it would definately alter the sound quality ? Mixvibes has a feature like that (Not that i am saying mixvibes IS better ? duh !)

Well, I tried MV 4 Pro yesterday, and there's one BIG problem with it: the BPM detection is really tooo slow, and you always need to scroll wehn you use a resolution of 600*800
