I actually tried that but I was unsure if that’s the best option ((L +R)/2). There seem to be certain cases where this could lead to the signal getting cancelled-out, and the signal level can get lowered for songs that have very different left/right channels.

Is that solution the standard approach for downmixing stereo to mono?

Thanks!


(L+R)/2?

no.

(L+R) is "standard".

and, depending on what level you are coding, using one extra
