Pedalboard: Spotify’s Audio Effects Library for Python

Pedalboard is a Python audio effects library designed to bridge the gap between professional audio software and Python code. It’s built on top of JUCE, the industry-standard framework for performant and reliable audio applications. Just like a professional DAW, Pedalboard supports a number of built-in audio effects, as well as third-party VST3® and Audio Unit plugins. And just like a DAW, Pedalboard prioritizes speed and quality: in basic tests on common developer hardware, it’s up to 300 times faster than the currently widely used packages for Python audio effects.

If you’re interested in trying out Pedalboard, it’s ready now. You can find its code and documentation on GitHub, where Spotify welcome contributions to the code. Installing Pedalboard on your computer is as simple as running one command: pip install pedalboard.
