scipy.signal.ShortTimeFFT.scaling#
- property ShortTimeFFT.scaling#
Normalization applied to the window function (‘magnitude’, ‘psd’, ‘unitary’, or
None).If not
None, the FFT slices may be either interpreted as a magnitude or a power spectral density spectrum (psd). If set to unitary, the STFT may be interpreted as a unitary mapping, i.e., preserving the value of the scalar product.The window function can be scaled by calling the
scale_tomethod, or it is set by the initializer parameterscale_to. Note that a window cannot to be scaled to be unitary. Usefrom_win_equals_dualto create a unitaryShortTimeFFTinstance.See also
