I probably haven't described my technique very well, sorry Rob, no
it's not parametric or brickwall filtering. I hope this clarifies...
Vicki's description for highpass filtering and ambience replacement
is a suitable one where there is no frequency overlap between noise
and subject Unfortunately, much vehicle or aircraft noise will
overlap with low-freq birdsongs, fundamental harmonics, mammal calls,
woodpecker drummings, bill-snapping, wingbeats...
So any effective processing will have to differentiate between noise
and subject sounds. Brickwall or parametric equalisation will achieve
limited results, as filtering will act on both noise and subject.
This is where DINR is so versatile. DINR is a noise reduction plug-
in, but it has more control and versatility than most other nr plugs
available. What I'm describing here may only be applicable to this
software, I'm not sure how it could be done using other plugs, sorry.
The way I approach cleaning up say, aircraft noise, is to:
