Actually there are plenty of tutorials on the internet.

http://en.wikipedia.org/wiki/Fast_Fourier_transform

http://www.google.co.nz/search?hl=en&num=100&ei=UAJdSpybOI_-tQOKyr21Ag&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=fast+fourier+transforms+tutorial&spell=1

They vary from basic thru to very complicated and specific.
