WebThe minimum K at which a pruned FFT becomes faster will depend upon the context, but we have observed benefits below from a pruned FFT (compared to Goertzel) for K as small as 10 with N of 10 5 (where Goertzel is orders of magnitude less accurate). FFTW does not currently implement any general pruned FFT algorithm. http://fftw.org/ loctite 680 sds sheet
