Yep, ffmpeg is the common workhorse for all kinds of audio and/or video 
conversions. Get it from https://ffmpeg.org/download.html or from your 
OS's package manager. Ffmpeg is very versatile, with the disadvantage 
that it can be quite a chore to figure out the correct command line for 
your use case. In this case, you'll probably need something like this 
(from https://stackoverflow.com/a/16376637/59122):

     ffmpeg  -i Kalimba.mp3 -c:a aac -vn Kalimba.m4a

(for auto MP4 files, .m4a is commonly used as the file extension)

To execute ffmpeg from your Python script, use the subprocess module.
