This is a weekend project for me - when I found that Krisp (and hence Discord) wouldn't support Linux, I set out attempting to create a user-friendly GUI which allows you to easily suppress background microphone noise. Do note that this is essentially just a GUI wrapper & nicer usage/installation experience for Werman's noise suppressor plugin for PulseAudio (<a href="https://github.com/werman/noise-suppression-for-voice" rel="nofollow">https://github.com/werman/noise-suppression-for-voice</a>).
