Detect BPM of audio and automatically align slides to it

[kongo09]

I often find myself using a stopwatch to count and time the beats of an audio track, calculate the bpm and duration of the measures and then adjust the slide duration to it, starting the first slide with the first beat.

This could be automated, either by just displaying the bpm / time per measure info in the interface and leaving the adjustment to the user, or by selecting an audio track and some sligts and offering a "match to beat" function.

Here some insights and code on how to find the bpm programmatically: https://github.com/chrvadala/music-beat-detector
