I’m making an Android application where I need to slow down the audio being played so the user can hear the sentences clearer. I have no idea how to approach this. While I do know a little about signal processing I do not know how to incorporate that with the Android. Are there any APIs or something that can help me?
Thanks
I guess this is what you want. There is a method for setting the playback rate, here ->
