I'm making a music player for android and I would like to get the average BPM (maybe also frequencies or tones) of a song BEFORE playing it, so I can show the user some info about the song, I know I probably have to open a stream and apply some maths to it to get the data I need, but I don't know how to act, can anyone help me?

Answer 1

I finally found the solution! I'm using the Minim java audio library, which can performs offline analysis on the audio buffer :) http://code.compartmental.net/tools/minim/manual-minim/

Answer 2

You can use the FFT

FFT library in android Sdk
