Is that all that's in that mic? Are your videos supposed to be silent except for that ambient noise?
It's far more common for people to say that their
voice isn't there, in which case we'd tell you to check the
Audio Monitoring and
Tracks for that mic:
and the
Audio Track selection on the
Output->Recording tab:
But since you say something else, the assumption is that all of that is correct, your voice
does work, and there's some kind of Filter involved:
I don't think a Noise Suppressor would do it, since that sort of thing is designed to remove constant sounds like electronic hiss, fans, etc.
A Noise Gate probably *would* cut out a keyboard and mouse, if they happened in isolation. You'd still hear them under your voice, but you'd have to listen for them. But since you *want* to hear them, I doubt you're using one. If you are, take it off.
