PyRubberband¶
A python wrapper for rubberband.
For now, this just provides lightweight wrappers for pitch-shifting and time-stretching.
All processing is done via the command-line through files on disk. In the future, this could be improved by directly wrapping the C library instead.
Example usage¶
>>> import soundfile as sf
>>> import pyrubberband as pyrb
>>> y, sr = sf.read("myfile.wav")
>>> # Play back at double speed
>>> y_stretch = pyrb.time_stretch(y, sr, 2.0)
>>> # Play back two semi-tones higher
>>> y_shift = pyrb.pitch_shift(y, sr, 2)
