Webb1 dec. 2016 · I’m trying to do parallel FFT on an 8 core (4 CPUs, 2 hyperthreads / CPU) machine, and I’m basically seeing a little less than 2x speedup going from 1 core to 2, and then none whatsoever between 2 and 8. Is this expected? I don’t know much about parallel FFT algorithms, is this indicating memory is a bottleneck? Anyway, I suppose this could … The short-time Fourier transform (STFT), is a Fourier-related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. In practice, the procedure for computing STFTs is to divide a longer time signal into shorter segments of equal length and then compute the Fourier transform separately on each shorter segment. This revea…
