Description: 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 though 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-The Fast Fourier Transform (FFT) allows us ers spectrum to view the content of an audio sign al. The FFT code presented here was written by Do n Cross though his homepage appears to have subs equently been taken down. Rather than explain t he mathematical theory of the FFT. I will attempt to explain its usefulness as it re Lates to audio signals
