One can automate the parameters of an EQ - I do it day in and day out in Pr=
o
Tools. For instance, a notch filter tracking the frequency of an airplane
fly-over.
In many ways, typical single-ended noise reduction systems (i.e. Dolby Cat
43, cat 430, Waves C4, other multiband downward expanders) act as a
threshold based automatic EQ, supressing frequency bands when they drop
below a threshold.
If you're looking to remove offending noises, look at Izotope RX - the
stand-alone app not the plug-in.
in the paraphrased words of purist-engineer mickey hoolihan, "any audio
processing is objectively a degradation"
