# 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_to` method, or it is set by the initializer parameter `scale_to`. Note that a window cannot to be scaled to be unitary. Use `from_win_equals_dual` to create a unitary `ShortTimeFFT` instance.
