The FFT in Numerical Recipes in C uses the Cooley-Tukey Algorithm, so in answer to your question at the end, the int sign being passed allows the same routine to be used to compute both the forward ( sign=-1) and inverse ( sign=1) FFT. This seems to be consistent with the way you are using sign when you define theta = sign * (2*pi/mmax). Share

The Fast Fourier Transform (FFT) allows users to view the spectrum content of an audio signal. The FFT code presented here was written by Don Cross, his homepage appears to have subsequently been taken down. Rather than explain the mathematical theory of the FFT, I will attempt to explain its usefulness as it relates to audio signals.
