FileNotFoundError on startupinfo

I ran pip install ffmpeg, but installing that lib didn't remove the warning.

Is this error only occurring if you try to run the program with .wav files? ffmpeg always seemed a little buggy to me so I'm not surprised it looks to be involved in this error. Unfortunately, I don't really understand what's going wrong here. My instinct is to suggest trying again with a .mp3 file or .ogg file because I know those work, but obviously that is only a workaround and not a solution.

Can you let me know if you get the same error with different format song files?

To install ffmpeg on Windows you have to go to their website, download the Windows .exe files, then add those to your path. More detailed instructions can be found here: https://www.youtube.com/watch?v=qjtmgCb8NcE

The mp3 gives an unknown format error, giving me the impression that mp3 isn't supported (error trace below). I'll try to find a different mp3 in case there's something weird with the one I'm using.

Installing ffmpeg fixed the FileNotFoundError error. Running on an ogg seems consistent, but it annoyingly deletes the ogg file. The KeyError is now the primary error, but seems to be most common with the 'segmented_HMM' model when using wav or mp3 while using ogg seems reliable regardless of the model. Thank you for your help. Now to see what they look like in game 😄

I just fixed this problem. It shouldn't delete the original file anymore.
