I’ve found profile based reduction works very well on many noises, but needs a clear sample of noise only, as the noise sample has to be analysed to create the profile.
I have tested against large doses of fan noise, and used sucessfully against hall noise of air conditioning, chair squeaks and suchlike - the key is finding a sample that contains the unwanted noise and no wanted audio. According to the manual, it works only for steady noise, but, at least using the similar function in Exact Audio Copy wave editor, it seems to be effective against any noise which can be sampled - eg. if the sample includes a chair squeak, then similar chair squeaks will be reduced.
The declick filter will be for “hard” clicks, some will only handle digital glitches, others are set up to tackle record scratches.
