I'd be quite interested in such an article, again, my goal (besides VoIP) is screencasting and/or streaming, so any bit of advice someone with experience might have is greatly useful.

I'll look into expansion and compression, and I could implement a wet/dry setting that multiplies the source samples and then mixes them into the result, if I understood the concept right.

EDIT: RNNoise seems to be alright when it comes to canceling noise during speech too, I didn't notice it overdoing it.
