Fast Fourier Transform, FFT) – algorytm wyznaczania dyskretnej transformaty Fouriera oraz transformaty do niej odwrotnej.

An Introduction to the Fast Fourier Transform
WitrynaAn FFT is any method to compute the same results in N log(N) operations. All known FFT algorithms require N log(N) operations. To illustrate the savings of an FFT, consider the count of complex multiplications and additions. Evaluating the DFT's sums directly involves N2 complex multiplications and N(N−1) complex additions. Witryna11 lip 2016 · FFT to spectrum in decibel. Here is a 10 seconds-long 440hz sine wave normalized at 0 dBFS. When computing the STFT (with the code below) of this audio file, I noticed that max (abs (STFT)) is around 248.33. (more generally, it seems to be approximately fftsize/4 for this particular file). allegro internet mobilny
