Frequencies compression (as peak one) allows you
boost the overall volume
of your track which in turns increases its loudness <=> RMS.
Of course you must take care of peaks but meters (and ears) are your
friends.

Thank you for remind me on this article Ron. It was one of the first that
I
discovered when I started using Linux Audio. But hey, it took me a whole
year to figure out how all the different audio apps work here in Linux and
which ones are useful to me, so I lost sight of that one, I must admit. I
will take my time to study it a bit closer.
