title: How to add sound effects on Android?
body: <p>I would like to write an App, that picks up sound from the mic, adds effects to it and plays it back in realtime.</p>
  
  <p>If found <a href="http://developer.android.com/reference/android/media/AudioRecord.html" rel="nofollow noreferrer">AudioRecord</a> to pick up sound from the mic and <a href="http://developer.android.com/reference/android/media/AudioTrack.html" rel="nofollow noreferrer">AudioTrack</a> 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 <a href="http://code.google.com/p/android/issues/detail?id=60" rel="nofollow noreferrer">in this issue report</a> pointed to from <a href="https://stackoverflow.com/questions/1971463/sound-effects-manipulation">this SO question</a>.</p>
  
  <p>My question is: How can I do this on Android? Can you recommand any libraries?</p>
