DSP Algorithm Libraries

[jksuperstar]

Just putting a place holder for DSP code to go. Libraries of algorithms, whatever. Any language is welcomed! C, assembler for your favorite DSP or uController, or maybe chuck? Please add useful links & files!

for starters:

Good initiative jk!

Lots of algorithms, code examples in various languages:

As posted to the music-dsp list recently:

A Collection of Useful C++ Classes for Digital Signal Processing

This collection provides lots of useful IIR filter types.

Edit: project moved from sourceforge to google.

And of course if people are looking for FFT or sample rate conversion libraries, these are the most prominent ones:

FFTW, aka "Fastest Fourier Transform in the West"

Secret Rabbit Code (Sample Rate Converter)

I've made this topic a sticky.

Please feel free to add anything of interest!

Stephan Bernsee, proprietor of The DSP Dimension and creator of the exceptional Neuron synthesizer (among other things), has a page with some very useful tutorials, papers and libraries concerning FFT based pitch shifting and time stretching.

Jet over to The DSP Dimension main page: Signal Processing Tutorials & Software.

Or head straight for the downloads section if you're in a real hurry

This isn't strictly source code, though it does have some:

It's sort of a walk-through to creating a basic synthesis environment including various synthesis building blocks, effects, sequencing, etc. There is also a link to a project on sourceforge, including a compiled Win executable. From the site:
