Post processing noise reduction...

I'm in the same boat as Ted, tgos3, as far as living in a high noise
environment is concerned. I read Ted's request and thought, wow, is this
fellow my neighbor?  Then I read he's down south somewhere so that ruled
that out...

I'm also looking for information on post processing noise reduction/removal=

software and at present I also use Audacity.  I'm mostly interested in bird=

sounds, songs, and calls and I find that while Audacity has a lot of great=

editing tools, to my way of thinking, the noise removal function is not one=

of them.  It is a powerful tool, it will really knock the noise down at but=

at the expense of modifying all but the very strongest bird/wildlife
sounds. A real tin can alley if you over do it...

Maybe someone has some information that would help a beginner set up the
Audacity noise removal functions?  I'm using the default values and
reducing the dB setting from 24 to 12 dB which seems to help on low level
noise.

Let me draw you a verbal map, the mid and upper Cape area has a lot of nice=

wildlife spots, however few large or very quiet being bordered by roads and=

housing areas. There are heavily traveled highways going out both sides of=

the Cape with heavily used secondary roads networking the towns and
villages. There are many boat harbors along the coast and boats are loud,
add to that the Cape has quite a few airports along it, I have one 2 1/2
miles north of me, and another 4 miles north east of me.

My home borders a 15 acre treefarm which is loaded with wildlife.  However=

there are two major secondary roads intersecting only 100 feet from the
north west corner of the treefarm, one of these roads along the west edge
of the farm is the main road into the village and beaches, the other road
travels along the north edge of the Treefarm and is the highway bypass
going between two heavily populated villages...  We have two Adubon
wildlife areas close to me, one borders the road running between villages
and Rt.28 on the far side, the other is nestled between the road exiting Rt=

6 and Rt.6 which is the main highway out the cape. Both of these roads are=

heavy traffic all the time... Talk about frustration!

Point of this is, about the only hope of making decent sounding files of
what we hear and can record in this area requires heavy post processing,
mostly noise removal...

So, Dear Friends, what does one do besides sell out and move far, far away?

I'm hoping there is some software package that you know about that will
help...

Thanks for your help and advise...
