FFTW

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, that is, the discrete cosine/sine transforms or DCT/DST).

The FFTW package was developed at MIT by Matteo Frigo and Steven G. Johnson.

FFTW can be downloaded from official website
