Hello, I m getting this error when trying to run audiostretchy 1.3.1.
I tried uninstalling and reinstalling it with "pip install audiostretchy[all]" but it doesn't seem to help could you tell me how to fix this please?
I am getting this error when I run : audiostretchy m1.mp3 m12.mp3 -r1.25

Fixed. Run the upgrade:

python3 -m pip install --upgrade audiostretchy[all]

Thank you I seem to be getting this error now after upgrading:

Try again with:

python3 -m pip install --upgrade audiostretchy[all]

I had followed the code sample from https://pypi.org/project/pymp3/ for the Windows MP3 writer but it seems that the code example is wrong there. So now I made "set_mode" now instead of "set_mod".

Let me know if that helped.

I plan to rewrite audiostretchy to use a different back-end for MP3 reading and writing (https://github.com/spotify/pedalboard which will allow to do more cool things including running VST plugins), but that's not for now. :)

(On macOS it all works but I don’t currently have a way to test it on Windows, and the Mac & Windows versions use different MP3 libraries)

I am still getting an error. Also, it seems that when used with wav files audio-stretchy works fine on my computer, the problem only appears when I try to use it with mp3 files.
Here is the error I m getting now:

[twardoch]

It seems that you should convert to WAV with another app and only stretch WAV-to-WAV. That should work.

Fixing MP3 will take a while.

Hello, for anyone having the same issue, it seems this particular issue is caused by a small typo in save_mp3, attempting to use 'nchannels' rather than 'self.nchannels'. I opened a tiny PR to fix this here.
