FFTW (3.3) 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, i.e. the discrete cosine/sine transforms or DCT/DST).
We believe that FFTW, which is free software, should become the FFT library of choice for most applications.

Surely some fun to be had with that
Hopefully THIS is a decent way to package things.
Obviously some launcher stuff might be nicer in the long term for appropriate apps.
