PyCon US 2025: A Deep Dive into pedalboard, the Python Audio Processing Library

At PyCon US 2025, Peter Sobot, a machine learning engineer at Spotify, presented pedalboard, his Python audio processing library. This library leverages Python and NumPy for efficient audio manipulation, supporting various audio format conversions and effect additions, and seamlessly integrating with VST3 plugins. Sobot's talk provided a clear explanation of digital audio fundamentals and showcased pedalboard's capabilities, such as real-time audio effects and efficient streaming. He stressed the importance of avoiding loading entire audio files into memory in Python, advocating for stream processing to prevent memory overflows. pedalboard empowers Python developers with robust audio processing, simplifying development for audio applications.
