Doesnt work at all...
I used it listening to external songs. Tried on 20 different songs from different genres. Not accurate on 1. I get a bpm from release, mixmeister, then Virtual Dj, so we have an accurate start point. It was not only way off but would give me different reads on the same song if I ran it 3 times. Horrible accuracy, how did they test this?
