I am working on a music player in which I need to change tempo (playback speed of music) without changing the pitch.

I'm not able to find any native android class to do so. I tried SoundPool but it doesn't work with large music files and it also doesn't seems to work on many devices. I also tried AudioTrack but again no luck.

Now I am trying android NDK audio example which use OpenSL ES to handle music. Now I just want to add set playback rate feature in this example.

Can anyone show me how do I add change playback rate function in it?
