Simple BPM Detector

I used this to tune the pendulum on a traditional weight powered clock. I used the metronome setting and dieled everything for max accuracy. I tested accuracy by having it listen to a few digital metronomes and it was dead on. After setting the pendulum timing on the clock I was able to sych it perfectly with a metronome set to the same timeing the app was reading from the pendulum. All in all I'm satisfied with the accuracy and it works really well for this application.

So far so good. I'll be trying this to calibrate clockworks. I believe people's issue is misunderstanding sound and rates. End calculations do jump around, although with a long term pattern. Meaning it can probably be filtered out in the settings. Take time to learn something before leaving rude comments.

Works well. I tested it against music I have created in my DAW and it was good, never more than +/- 2bpm out and frequently dead right. The more pronounced the beat, the quicker and more accurately it gets the tempo. However it does struggle with music that does not have a strong bass or kick drum groove. Tapping the mic in time with the music, as someone else suggested, helps in those cases. It occasionally displays a bpm that appears very wrong but multiplying or dividing the displayed tempo by 2 often gives you the real bpm.
