It's harder on Windows, on Linux it is built-in to Pulse Audio. Here is a solution based on a plugin for a system wide equalizer called Equalizer APO. https://github.com/werman/noise-suppression-for-voice Because it is a system wide plugin, you can use it for any software that takes you mic as input. Here is a detailed guide for using it. https://medium.com/@bssankaran/free-and-open-source-software-noise-cancelling-for-working-from-home-edb1b4e9764e Warning, I have not tested it on Windows, it is supposed to work on Windows, Linux and Mac. Hopefully this will help you. Answer from BillDStrong on reddit.com
