librosa.effects.hpss¶
- librosa.effects.hpss(y)[source]¶
Decompose an audio time series into harmonic and percussive components.
This function automates the STFT->HPSS->ISTFT pipeline, and ensures that the output waveforms have equal length to the input waveform y.
Parameters: y : np.ndarray [shape=(n,)]
audio time series
Returns: y_harmonic : np.ndarray [shape=(n,)]
audio time series of the harmonic elements
y_percussive : np.ndarray [shape=(n,)]
audio time series of the percussive elements
