I couldn't get it to work. Here's the full error stack. The file is an mp3 file with MPEG Audio Layer 1/2 codec (mpga), at 48khz

Next time, please try to include as many details about your setup as possible like OS version, pyenv/conda environment, python version, etc. as it greatly helps to trace down issues and improve the software and its documentation.

From the error, it seems that you are missing ffmpeg. You can find instructions for how to install ffmpeg on your version of Widows. If you are using conda, you can try calling conda install ffmpeg. Hope this helps.
