remucs 0.4

Demucs wrapper for remixing audio files with additional customizations

Remucs

The purpose of the remucs command line tool is to extract the individual stems from a mix and remix them again in a certain way, e.g. by adjusting the volume gain, left-right channel balance and last but not least, applying transient-preserving pitch shifting. Since the stem extraction is based on the adefossez/demucs engine, the stem choice is restricted to the drums, bass, vocals and other sources.
