DSP algorithms can be tricky to implement. Here, we provide free/open software to implement key DSP algorithms.

The following packages provide C source code (unless noted) to implement common DSP algorithms. The code is intended not only to be "instructive" but also "useful": most routines are efficient enough to be used as-is in real DSP applications. Most packages include test programs. See the "readme.txt" file in each package for more information.
