What is a noise gate?
Definition
A noise gate silences an audio signal whenever it falls below a set volume, removing background noise between words.
Fan hum, room tone and keyboard rustle are quiet compared with a voice. A gate lets the voice through and closes when it stops, so pauses are clean. It does not remove noise that happens while you are speaking.
