I think what you want is not L + R. That would include signals which
exist only in the right or left channels. The center channel should
include only the signal that is common to both L + R. (If your definition
of "center" means that the signal strength is equal in the right
and left channels. So what you want is a common mode signal extractor.
I don't know the right circuit for that, but what do I know I'm
a software person :^) ...
