scipy.signal.ShortTimeFFT.phase_shift#
- property ShortTimeFFT.phase_shift#
- If set, add linear phase - phase_shift/- mfft*- fto each FFT slice of frequency- f.- Shifting (more precisely rolling) an - mfft-point FFT input by- phase_shiftsamples results in a multiplication of the output by- np.exp(2j*np.pi*q*phase_shift/mfft)at the frequency q *- delta_f.- The default value 0 ensures that there is no phase shift on the zeroth slice (in which t=0 is centered). No phase shift ( - phase_shift is None) is equivalent to- phase_shift = -mfft//2. In this case slices are not shifted before calculating the FFT.- The absolute value of - phase_shiftis limited to be less than- mfft.- See also - delta_f
- Width of the frequency bins of the STFT. 
- f
- Frequencies values of the STFT. 
- mfft
