Unless you're really into maths and numerics you'll probably learn nothing useful. That might be actually the reason why DFT algorithms have been re-invented or re-discovered a couple of times during history: 1805, 1965, 1984 [4]. If I may suggest: read up on DFT and leave FFT to the the maths geeks. [3] http://www.fftw.org/ [4] http://en.wikipedia.org/wiki/Fast_Fourier_transform#Cooley.E2.80.93Tukey_al… Cheers! robin
