Boost centre channel when downmixing


When playing a 5.1 file on 2.0 audio setup conversations are sometimes a bit hard to follow. OSMC had a great feature to deal with this; it had a feature that allowed the center audio channel to be amplified when playing a 5.1 file on a 2.0 audio setup. A nice trick to do hear conversions perfectly.

It would be great to have such feature… for ffmpeg-based solutions the required code appears to be quite simple… see for some code snippets :wink:
