Thanks for > the explanation :-) Well, I'm still not sure what you mean by "It may only take more time with less nodes". if I want to take the FFT of each frame, I only need one FFT block. I don't see how to do that with more than one FFT block, except by explicitly parallelizing. Jean-Marc -- Jean-Marc Valin Universite de Sherbrooke - Genie Electrique valj01 at gel.usherb.ca
