Cooley–Tukey FFT algorithm - Wikipedia

WebCooley–Tukey's fast Fourier transform (FFT) algorithm is a method for computing the finite Fourier transform of a series of N (complex) data points in approximately N log, N operations. FFT operates on inputs that contain an integer power of two number of samples, the input data length will be augmented by zero padding at the end. http://wwwa.pikara.ne.jp/okojisan/otfft-en/cooley-tukey.html
