NoiseTorch is an easy to use open source application for Linux with
PulseAudio. It creates a virtual microphone that suppresses noise, in
any application. Use whichever conferencing or VOIP application you like
and simply select the NoiseTorch Virtual Microphone as input to torch
the sound of your mechanical keyboard, computer fans, trains and the likes.

It is based on https://github.com/werman/noise-suppression-for-voice/,
that will also need to be packaged.

Just a heads up that there are some "noises" (pun intended) about a
possible compromise of the NoiseTorch source code upstream:

Followup in:

https://github.com/lawl/NoiseTorch/issues/254

It would seem wise to hold off on any packaging until the above is resolved.
