working FFT c# project

Hi Btb4198,

A Fast Fourier transform (FFT) is an efficient algorithm to compute the discrete Fourier transform (DFT) and its inverse.

Here is an open-source C# mathematics library with FFT algorithms:http://www.exocortex.org/dsp/

It is a good sample about FFT, you can have a try:http://www.codeproject.com/Articles/44166/2D-FFT-of-an-Image-in-C

Thanks.
