I'm trying to use Mathematica to find out the beat rate of a song.

The image below shows some markups I made in another program in milliseconds.

enter image description here

I was able to find that there is a pattern every second.

In others words 120 BPM

Is there any way to achieve this?

I tried the Periodogram, but it was not enough:

Periodogram[Import["C:\\Users\\LMC\\Desktop\\Teste.wav"]]

enter image description here

This is the sound I analyzed.
