BPM Calculator

On rare occasions, my machinations require the BPM of a song for audio synchronization shenanigans. I've typically had to tap out the BPM, since online sites are unreliable and have inconsistent answers, but I've known for a while that it's also possible to do programtically.

This page uses the wonderful web-audio-beat-detector to try and predict the BPM, right here in your browser (so more of a guesser than a calculator, haha). I couldn't find any demo of it, so I ended up making this one.
