A GUI frontend for @werman's Pulse Audio real-time noise suppression plugin.
Cadmus is a graphical application which allows you to remove background noise from audio in real-time in any communication app. Cadmus adds a notification icon to your shell which allows you to easily select a microphone as a source, and subsequently creates a PulseAudio output which removes all recorded background noise (typing, ambient noise, etc). If you find the application useful, leave a star — it helps!
