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

Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples.
