Would you mind adding a little more detail to your post? For instance, I am not sure how and where to implement your code within android itself. Especially with regard to the processing audio part, which is what I really need from this post

It also took me a little while to figure out that you were using Kotlin.

Thanks for your comment. There can be any number of places that you could put this code which is why it's not mentioned in the post. You could add it to the Activity or Fragment that is supposed to handle the UI for beats detection.
