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.
