Stereo to Mono Sound Is there a way to digitally convert stereo sound tracks to mono ones, while playing?
I need this feature because sometime I split my headset with other people, and hearing only one channel is quite awful. 
I do not want to change my music player, which is n7player (paid).
My phone is Galaxy S4 with Cyanogenmod 11 (Kitkat 4.4.2).

The only answers I was able to find were to use PowerAmp player, but again, I don't want to switch to it.
On Android 4.4:


From your homescreen, hit the Menu key and open System Settings
Go to Accessibility, tap cancel on "need a screen reader" to bypass / scroll down to "Mono Audio"
Uncheck box


Done!
