many programs let you do that, it is usually called noise reduction (atleas=
t in adobe audition/cool edit that i use. you select a small section where =
you only have unwanted sound and ask the=A0software to sample it. It then c=
reates quite complex filters to complement that noise and removes it from t=
he recording. it=A0can work very well indeed.

Subject: [Nature Recordists] Filtering
I've read somewhere on this or the other group, (but can't now find
it) that some audio software allows you to copy a piece of the
recording and use that as the basis of the filter. Does anyone
remember this? If so, what is that software.
This allows you to copy an area that is silent of bird calls and is
just the noisey background, past that into a filter, and remove that
sampled sound from the recording.
Is this something I may have actually dreamt rather than read. As I
said, I can't find the reference to it.
