It would be nice to have a setting for adjusting audio focus. This is very useful for people who use PipePipe for music listening. LibreTube and Ymusic (closed source) have it.

Basically it's an option to keep playing the audio in background even when another audio is playing OR when you are recording sound (except for calls). It should be fairly easy to implement too.

Thanks.
