Hello everybody,
I record my voice, stop and start and each time you can hear the mouse click. I tried selecting one mouse click as noise profile, then selected all of the track and clicked on noise reduction but it doesn’t seem to work. Any idea what parameters to set, or any other way to get rid of all the mouse clicks with one single… mouse click? 
Thanks!
Actually, that should have done something. You can try collecting a bunch of clicks on a separate track and use that as the profile. Maybe boost the clicks so they’re louder. That will give Noise Reduction a running start and the profile should hang around until you restart Audacity.
There’s also Noise Gate (make any sound below a set volume vanish) although that one’s harder to adjust.

Sorry. Had to leave there.
