There are a few options that let you use RNNoise. (I posted another comment a bit further up on how to pipe your audio through OBS to implement this. There are undoubtedly simpler options.)

In my experience, it does a great job cancelling out keyboard clicks and clacks. Even if I sit here and slam on my spacebar harder than I'd ever hit it even writing an angry email, it's cancelling it all. And I've never had an issue with it _not_ picking up my voice.

If you're just looking for _a_ solution to the problem, I'd give something with RNNoise a try.

If you have an RTX card, get nVidia Broadcast.

If you have a non-RTX card (like a GTX 1070), get RTX voice. Despite the name, it does not require an RTX card.

Seriously, nVidia's noise removal is absolute magic, as far as I'm concerned. https://youtu.be/uWUHkCgslNE

I actually tried writing a version of this for windows just an hour before this was written. Usually when I do this I find there is one already just as I finish it, but if not then I’ll put it on GitHub within a week. Will post another msg here if I do.

Nvidia Broadcast if you have a recent GPU

No. Get a decent OS.
