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?"
Sinectonalysis has a few libraries for linux. I have no experience with them though ...
For FFT there is fftw and djbfft
RFC1925
djbfft is located here
