John,

As others have said, this is a not uncommon noise reduction ("NR")
strategy. You can do this using the built-in noise reduction tools in
Samplitude, the package I use, for example.

Generally speaking, it is somewhat tricky to get pleasing results with
this kind of tool; it is easy to go too far -- even if you don't get
audible artifact (usually digital 'chirpiness', like an
over-compressed file), it is easy to get "lifeless' sounding results.
In my 'sound art' life I have used strong NR settings to intentionally
distort sounds, actually. I think the lesson is that a little noise is
preferable to over doing it!

Someone here has said on occasion that it is better to do a few very
light passes, than one deep passage.... was that you Dan? Rob?

 best,
  aaron
