I'm sure it's been answered many times, but here's my question:
For loudness evaluation, how's EBU R128 "better" than ReplayGain?
(Or why use EBU R128 instead of ReplayGain?)
(A link to the suitable InterWeb resource would be appropriate)
B.T.W, there's another EBU R128 utility to normalize audio files:
https://github.com/jiixyj/libebur128
It can add ReplayGain tags to existing mp3 files. Nice!
I add to checkout commit 1c0e8da to avoid linking errors,
as mentioned here:

I assume the
ebumeter output is more for making things sound even
(between different pieces) and not directly a tool to max out
anything, is that right?
That is absolutely right. Systems such as EBU-R128 exist because
it makes perfect sense to make things sound even (avoiding your
listeners having to adjust the volume all the time), while 'maxing
out' serves no useful purpose at all - it just destroys the sound
if taken too far. In other words, such systems exist to *stop* you
'maxing out' everything.
Lame's 'replaygain' meausurement has the same purpose. Note the
value for the file in your original post: -9.1 dB. That means
that an intelligent mp3 player will *reduce* the level of this
file by 9.1 dB when playing it - it is already much too loud.
