Have you looked at the Intel site?Or the ATLAS BLAS libraries, probably on netlib. and FFTW and DJBFFT, of course. -- Andrew

All those SVDs and EVDs that many tecniques of "modern" DSP need... Rune

I operate in a Windows XP Pro enviroment I have a LARGE amount of raw audio data in WAV format. The frame size of interest would range from ~.02 sec to .1 sec. I would like to generate spectra of this data on a per frame basis. 1. amplitude or power is a moot issue 2. speed is secondary [ I'm using stored data ] I have two constraints: 1. minimal financial resources -- this is by denotation rather than connotation an "ametuer" project. 2. I don't really have math background to develop my own solution, but have enough to "almost" ask the "right" questions. { Rune, Fred, Jerry I'm attacking my previous question from a different direction. ;]

If it does, either buy it -- it's not expensive by my standards if you decide to buy, but if it works for you, ask here if there's a free or cheaper program that does only the task you need.

Octane, Octave or something like that. Does anyone know about this? Rune
