Spotify has developed and open-sourced Pedalboard, a Python audio effects library built on JUCE. It allows programmers to use studio-quality audio effects in their code, bridging the gap between professional DAWs and Python. Pedalboard supports built-in effects, VST3/AU plugins, and is significantly faster than existing Python audio effect packages. It has found applications in ML data augmentation, content creation automation, and creative audio manipulation.
