We are adding a function to our Android app, in which we would like to get the music tempo/BPM (either playing in our own app, or in another app), and then visualize the song or music with FFT or similar stuff. Something synchronizes like this: https://www.youtube.com/watch?v=VVrf89SXvTM
Can anyone nice to teach us how can I get the music tempo? Or any tutorials? I appreciate any provided answer.
