DFT is a transformation, and FFT is an algorithm to implement DFT, so how is it that you seem to have separate functions for DFT and FFT? I have used FFT and IFFT myself for an audio spectrum analyzer and they worked as expected. I checked the results against Matlab. And AFAIK, I tried both float and double with no noticeable difference. Regards, GUILLE ---- Guillermo Rodriguez Garcia XXguille AT XXiies DOT XXes (ya sabes :-)
