I've been using obs for quite a while and only just now got into audio filters. The problem is that when recording, it's very easy to hear my mechanical keyboard and my mouse. By adding a noise gate, compressor, and suppression, I've eliminated every problem except some keyboard and mouse noise (the sound of picking it up and putting it down when moving across the mousepad, not clicking). I've placed a washcloth under the keyboard and it helped dampen some sound, but not enough. My microphone is a blue yeti, and I've turned the gain as low as it goes. Everything besides the filters and windows microphone levels being 88% is vanilla. All 3 microphone filters are included below, as well as my setup. The gain is on the lowest setting, and my blue yeti is on cardioid mode on a boom arm and shock mount.
