Thanks for bringing this up. Is the audioop-lts actually this https://github.com/AbstractUmbra/audioop? It looks like only support python version >= 3.13, right?

I haven't played with piper for a while. I have trouble in installing piper on my machine. Check https://github.com/p0n1/epub_to_audiobook?tab=readme-ov-file#piper-tts. So this project didn't include the piper package. I leave it for users to install manually.

Hello!

I should have provided more information on the initial pull request.

OS: Fedora 41
Python: 3.13.1
Piper: 1.2.0 <-- Installed from binary
audioop-lts: 0.2.1

I followed the installation section of the README.md to get started. After running the following command Python produced errors, which searches lead me to AbstractUmbra/audioop-lts. I did a pip install audioop-lts, and it resolved the error. I searched for ModuleNotFoundError: No module named 'pyaudioop'

Note: Piper was installed via git clone directly using the binary and not pip install piper-tts as noted in the troubleshooting section of the README.

Command
python3 main.py <myepub>.epub ./mybook --tts=piper --piper_path=../piper/piper --model=../piper/en_US-john-medium.onnx

Full Error:

need to specify specific version to lock it

[LinuxEclipsed]

I modified the commit to reflect the correct version.
audioop-lts==0.2.1

[Bryksin]

Approved

@p0n1 merge if you are ok with it

After upgrading Ubuntu to the latest version, which brings python 3.13, Edge TTS failed with ModuleNotFoundError: No module named 'audioop'. Applying this change fixed it.
