scipy.signal.ShortTimeFFT.fft_mode#
- property ShortTimeFFT.fft_mode#
- Mode of utilized FFT (‘twosided’, ‘centered’, ‘onesided’ or ‘onesided2X’). - It can have the following values: - ‘twosided’:
- Two-sided FFT, where values for the negative frequencies are in upper half of the array. Corresponds to - fft.
- ‘centered’:
- Two-sided FFT with the values being ordered along monotonically increasing frequencies. Corresponds to applying - fftshiftto- fft.
- ‘onesided’:
- Calculates only values for non-negative frequency values. Corresponds to - rfft.
- ‘onesided2X’:
- Like onesided, but the non-zero frequencies are doubled if - scalingis set to ‘magnitude’ or multiplied by- sqrt(2)if set to ‘psd’. If- scalingis- None, setting- fft_modeto onesided2X is not allowed. If the FFT length- mfftis even, the last FFT value is not paired, and thus it is not scaled.
 - Note that onesided and onesided2X do not work for complex-valued signals or complex-valued windows. Furthermore, the frequency values can be obtained by reading the - fproperty, and the number of samples by accessing the- f_ptsproperty.- See also - delta_f
- Width of the frequency bins of the STFT. 
- f

- f_pts
- Width of the frequency bins of the STFT. 
- onesided_fft
- True if a one-sided FFT is used. 
- scaling
