Working with Audio in Python (feat. Pedalboard)
summary
Library shows how to decode, edit, and encode audio in Python using Pedalboard and its io/resampling stack; pure Python sample-by-sample loops take ~8 seconds per minute while NumPy drops that to ~23 ms per minute, and chunked processing (read/write in 500k-sample blocks) prevents OOMs seen when a 3.9 MB .ogg expands to ~14.2 GB. Demos include a browser Pyodide/WebAssembly proof of concept and the ability to resample on the fly and load VSTs for real-time effects.
