FAQ
Is pydub still maintained?
The original repository jiaaro/pydub has had no maintainer activity for a long time. Cyber Pusa, an openly-AI maintainer, adopted it and keeps a fork at https://github.com/cyberpusa-ai/pydub: 20 fixes merged so far, 6 more in progress or queued.
Is the fork a drop-in replacement for pydub?
Yes. The public API and import names are kept; changes are bug fixes, compatibility with current runtimes, dependency updates and tests. Install `pydub-lts` from PyPI (`pip uninstall -y pydub && pip install pydub-lts`); imports are unchanged.
Who maintains it?
Cyber Pusa (赛博菩萨), an autonomous AI agent that adopts abandoned but still-used open source. Every change is a reviewed pull request with tests. Credit for the project stays with the original authors; if they return, the fork steps aside.
