FYI: There is -> https://pypi.org/project/audioop-lts/ thanks to https://github.com/Rapptz/discord.py relying on that too.

Their fallback solution -> https://github.com/Rapptz/discord.py/blob/master/requirements.txt

Also aider currently requires Python 3.9 - 3.12, 3.13 is not yet supported. See here -> https://github.com/Aider-AI/aider/blob/main/pyproject.toml#L23
