Been trying to search through the Internet. I can’t quite seem to find anything in regards to how to get the tempo/speed of a song, does anyone know any built in function or even a library?

Edit: I tried to use the Minim library and used `getTempo()` but that seems to fail.

Oh, how would I implement this if you happen to have an idea as I am really struggling to do it.
