Hi John--
Sorry about any confusion created. I use volume automation to reduce 
the peaks that would be inordinately loud _at the same time_ I EQ and 
boost volume.

To use normalization in the context of mixing assumes that loudest 
transient peak-- as your recorder created it-- is _ideal_ in terms of 
relative volume. My experience is that that birds and amphibians 
don't happen to perch at perfect distances and the insects don't 
respect my "no fly mic zone" etc. Using the loudest peak to establish 
overall track volume in a mix often translates into middle-ground and 
background subtleties that folks can't hear unless they're using 
headphones.

The reverse is true, of course. If one only wants folks to concern 
themselves with the foreground sounds and there's adequate separation 
in the original field recording, normalization is a quick way to 
greatly increase volume without creating over-modulation.

Why not just do a quick normalization and follow that with selective 
gain reduction etc and other measures? You can, and making further 
changes to a file that has been "bumped-up" to 24 bits and normalized 
at the same time seems to help preserve quality. I try to plan for a 
minimum number of digital generations that involve processing. 
There's a slight but pesky difference between real-time playback with 
EQ plugs and playback after the EQ from the plug has been digitally 
written. So, I usually equalize and do critical volume automation 
adjustments at the same time that I create the 24 bit "Submaster" 
(from a 16 bit or 24 bit field recording).  I boost gain with my EQ 
plugs and mixer settings making sure that the mix peak does not 
exceed -.3dB.  Its common for quite a few events to hover around the 
peak. Does this address your question? If not, let me know. Rob D.
