Sir,

I will not send you a program.

I will, however, direct you to some sites that will HELP you either write your own functions, or use one that is in the public domain.

Please feel free to visit these links at your leisure :

http://en.wikipedia.org/wiki/Fast_Fourier_transform
http://en.wikipedia.org/wiki/FFTW
http://www.fftw.org/

I hope you find this useful.

By the way, I was able to find this links by typing "FFT" into the Google Search Engine.

It took about 2 minutes of my time...
