Opus is a new open source lossy-format that replaces Vorbis and the outperforms all the other proprietary alternatives to it. However, what plays Opus on Android? Thus far the only thing I've found is Firefox! How come my browser can play Opus -- and none of my music players?
I even wrote Alex, the developer of PowerAmp he said,
something like that is planned - you can check for details here: http://forum.powerampapp.com/index.php?/topic/1794-poweramp-todo-listfeatures-in-progress/
And, it says nothing of Opus support in the future?
