I prefer to use FFTW which is a C library which does alot of tricks in the background to provide the fastest FFT for your requested size on your particular machine. There exists a number of wrappings which makes it available in other languages. You can also use Octave or similar for processing and FFT is also available. Some of them actually relies on FFTW nowdays. I am Linux-oriented, but I see no reason why these should not do their job well on Windows etc. Cheers, Magnus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
