Effects¶
Harmonic-percussive source separation¶
hpss (y, **kwargs) |
Decompose an audio time series into harmonic and percussive components. |
harmonic (y, **kwargs) |
Extract harmonic elements from an audio time-series. |
percussive (y, **kwargs) |
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. |
Miscellaneous¶
remix (y, intervals[, align_zeros]) |
Remix an audio signal by re-ordering time intervals. |
trim (y[, top_db, ref, frame_length, hop_length]) |
Trim leading and trailing silence from an audio signal. |
split (y[, top_db, ref, frame_length, hop_length]) |
Split an audio signal into non-silent intervals. |
