For example, if the original stereo recording has three singers at
equal volume panned hard left, hard right, and hard center, summing
to mono will make the guy in the center 3 db louder than the other
two.
Shouldn't he have been 3 dB softer to begin with (in the stereo mix)?
Yes and no. In order to sound like they're all three at the same
level, the center guy would be -3db in the left channel and -3db in
the right channel.
Why is that? In order for a signal s(t) to be perceived at the same
power, it should be split into s(t)/2 for the left and s(t)/2 for
the right. Then at the listening position it combines into
l(t) = s(t)/2 + s(t)/2
= s(t)
Thus the center guy should be 6 dB down (1/2 voltage) to sound the
same at the listening position. No?
