ModuleNotFoundError: No module named 'pyaudioop'

Hi,

I recently upgraded to python 3.13 and pyDub is no longer working.

I was using the following code to slow down a song,

from pydub import AudioSegment
song = AudioSegment.from_file(file1, format="mp3")
song.frame_rate = song.frame_rate / (song.frame_rate / int(slowmo_Amount))

but since upgrading, it throws this error.

Traceback (most recent call last):
  File "C:\Users\User\AppData\Local\Programs\Python\Python313\Lib\site-packages\pydub\utils.py", line 14, in <module>
    import audioop
ModuleNotFoundError: No module named 'audioop'

During handling of the above exception, another exception occurred:

In version 3.13 audioop has been removed from the python standard library.
One solution is to install auidoop-lts.

Thank you! This is working now. I have another found bug (will post again)

This seems to happen to everyone using Python3.13, a simple solution would be to use sys.version_info in the setup.py to install the requirement only when the Python-version is 3.13.

So this could be added to the setup.py:

dependencies = ["audioop-lts"] if sys.version_info.major == 3 and sys.version_info.minor >= 13 else []

And in the setuptools.setup()-function call:

setup(
    ...
    install_requires=dependencies,
    ...
)

That’s a typo.
Try: pip install audioop-lts
