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:

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)

Subject description: FFT based pitch shifting and time stretching
Reply with quote  Mark this post and the followings unread

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 Very Happy

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

http://basicsynth.com/forums.html

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:

Quote:
...this site does not explore any new or original methods of sound synthesis. The examples shown here are the way most synthesis software is implemented and has been implemented since the 1960s. Instead, this information is intended as an introduction to software synthesis with a focus on the practical problems of programming the sound generation routines and combining them in a way to produce an efficient working synthesizer.
