Effects¶
Harmonic-percussive source separation¶
hpss(y) | Decompose an audio time series into harmonic and percussive components. |
harmonic(y) | Extract harmonic elements from an audio time-series. |
percussive(y) | Extract percussive elements from an audio time-series. |
Time and frequency¶
time_stretch(y, rate) | Time-stretch an audio series by a fixed rate. |
pitch_shift(y, sr, n_steps[, bins_per_octave]) | Pitch-shift the waveform by n_steps half-steps. |
