Native Signal Processing for Linux

gtt asks: "Intel offers a Native Signal Processing kit for x86 processors, which can be used for processing sound and other such things. (Filters, FFT's, etc.) They only offer it as a Windoze library. Anyone know of any equivalent optimized signal processing libraries that can be used in a Linux program?"

FFTW

[Anonymous Coward]

For FFT's, it's very hard to beat FFTW (see http://www.fftw.org). Even though the library is portable, it dynamically adapts itself to the native architecture at runtime, generally beating the socks off of most other FFT solutions in terms of performance. The code falls under the GPL.

None known, VSIPL would be nice

I have looked around but found nothing.
One thing that would be nice is an
implementation of the VSIPL (Vector,
Signal, and Image Processing Library)
standard being developed at http://www.vsipl.org
They have some reference code written
in C available on their web site. It
is obviously not in optimized assembly,
but might get you on your way. They
have specified the library in such a
way that it can be implemented in an
extremely optimized way on many different
architectures.

lab stuff.

this may be slightly offtopic but look for all this under the linux site which has all the scientific software (not sure of the name..you might have to search for it). There's loads of scientific software (and libraries) on that site (>40 packages last time i checked)....you might try looking in the old databases which carried the linux software archives (before the days of freshmeat)...i found the link from there. i'll try and post it up if i come across it again. theres also some lab stuff (&drivers) for signal processing on that site.

I know a few ...

Sinectonalysis has a few libraries for linux. I have no experience with them though ...

For FFT there is fftw and djbfft

Ooooops (Re:I know a few ...)

Sorry, worng URL:

djbfft is located here
