This script creates a pulseaudio sink that will cancel noise in audio
streams sent to it, and then move it on to the default sink.
This means that other people's crackling, static background, gulping,
keyboard sounds, fan whirring, construction noise etc. are removed.
Some preliminary tests on TVL suggest that this actually works. The
parameter might need some tweaking ("50" is just the default value),
as there is some occasional crackling at the beginning/end of a speech
segment, but this is already *much* better than before.
