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.

Install Rubberband on OS X

brew install https://gist.githubusercontent.com/faroit/b67c1708cdc1f9c4ddc9/raw/942bbedded22f05abab0d09b52383e7be4aee237/rubberband.rb

Example usage

>>> import soundfile as sf
>>> import pyrubberband as pyrb
>>> # Read mono wav file
>>> y, sr = sf.read("test.wav")
>>> # Play back at double speed
>>> y_stretch = pyrb.time_stretch(y, sr, 2.0)
