Méthode scipy.signal.ShortTimeFFT.scale_to

Signature de la méthode scale_to

def scale_to(self, scaling: Literal['magnitude', 'psd']) 

Description

help(ShortTimeFFT.scale_to)

Scale window to obtain 'magnitude' or 'psd' scaling for the STFT.

The window of a 'magnitude' spectrum has an integral of one, i.e., unit
area for non-negative windows. This ensures that absolute the values of
spectrum does not change if the length of the window changes (given
the input signal is stationary).

To represent the power spectral density ('psd') for varying length
windows the area of the absolute square of the window needs to be
unity.

The `scaling` property shows the current scaling. The properties
`fac_magnitude` and `fac_psd` show the scaling factors required to
scale the STFT values to a magnitude or a psd spectrum.

This method is called, if the initializer parameter `scale_to` is set.
