Ah well.

It can't be the geometric mean. If it were, then whenever one channel is
silent and the mix is all the way at 9:00 or 3:00 for an instant, the mono
result would be silent. Also, whenever both channels are equal, (say, at
maximum), the geometric mean would be the same as that value. We know that
neither is the result we get.
(Maybe by "it" Ralph didn't mean Sony's secret algorithm, but in any case,
the geometric mean is unusable because silence in one channel mutes the
other.)
S> Ralph -> going to try to locate his old study books.....
Thank you for whatever you can find out. I hope there's an answer here, be-
cause mono-mode recording on MDs is useful not only for saving space but also
for centering off-center mono masters. It is really annoying to listen to a
song mixed entirely at 11:15 or 12:45 without a balance knob; a dub to MD in
monaural mode centers it perfectly.
