I would like to write an App, that picks up sound from the mic, adds effects to it and plays it back in realtime.
If found AudioRecord to pick up sound from the mic and AudioTrack to play it back. In between, I need some library to manipulate the sound, add effects or use some equalizer on it. This maybe achieved with the Java Sound API, but that seems to be missing as I read in this issue report pointed to from this SO question.
My question is: How can I do this on Android? Can you recommand any libraries?
