modulation.signal_utilities.audio_utilities.filtering.hilbert_envelope(signal: ndarray, *, n_fft: Optional[int] = None) → ndarray

Calculates the Hilbert envelope of a signal.

Parameters

• signal –

  The signal to calculate the Hilbert envelope of.

  Signal on which to calculate the hilbert envelope. The calculation

  is done along the last axis (i.e. axis=-1).

• n_fft – The FFT size to use. If not provided, it will be determined from the length of the signal.

Returns

The Hilbert envelope of the signal.
