However, I believe the psychoacoustic "model" of EBU R128 is superior,
although certainly not perfect (colleagues have mentioned to me ways of
cheating R128 to achieve higher programme loudness for constant LUFS
readings, but I've yet to see an actual demonstration).
But regardless of technical merit, I would always choose EBU 128 over
ReplayGain, because it has the magic letters "EBU" in it, and the
underlying measurement scheme has the even more magic "ITU".
Don't forget that any perceptive loudness normalization proposal is
basically a "non-agression pact" in the loudness war. If you don't nuke
my speakers (and wreck my music), I won't nuke yours. So it makes sense
to flock around the biggest fish in the pond, because their involvement
and statement of intent carries weight.
Until all broadcasters follow suit, those who behave are at a commercial
disadvantage, so the whole process has all the interesting properties of
a game theory problem.
For an euro-centric bastard like me, the European Broadcast Union is the
mightiest normative entity in the universe. Some weird people think
differently, but those take solace in the fact that the actual loudness
determination is governed by an International Telecommunication Union
standard (and that should be good enough for everyone :)
So yes, R128 is a very safe bet indeed.
