Carl, I assume this filter creates summed output of all channels in
order to create a somehow realistic rendering of auditorium loudness
according to EBU broadcast-specs. I have watched the numbers while
playing around with audio levels a bit, but currently I am not sure how
to use it.
That's about the size of it. I think its use is getting things into the
right ballpark when you either can't or won't listen to the audio in a
calibrated room (or at least a 5.1 system).
I imagine it is also useful when mastering to keep a track of how loud /
quiet you are and manage the effects of temporary threshold shift etc.
But I am no mastering engineer!
As you say, the only way to get the sound right is to listen to it; there
is not (yet!) any automatic short-cut.

Carl
