An open source C library for doing Fast Fourier Transforms (FFT) with and also comes with a small utility called fftw-wisdom that generates "wisdom" files that contain saved information about how to optimally compute Fourier transforms that are used by the library.

FFT's are mathematical operations that are especially useful in any sort of signal analysis and are used heavily in audio analysis applications and at any time you need to quickly convert complex waveform information into something else, like for instance converting them into a graphical representation.
