Name: Choosing the Best FFT Algorithm
ID: m12060
Language: English (en)
Summary: Power-of-two-length FFTs are usually best for general use when the DFT length is somewhat at the user's discretion. The best power-of-two algorithm may depend on the type of computer to be used. When FFTs must be of a specific length, a prime-factor algorithm when applicable or otherwise a common-factor algorithm usually provide fastest performance, while the chirp z-transform is a single, universal method for computing an FFT of any length.
