Noise gate

A noise gate mutes audio when it falls below a threshold, silencing the background between phrases while leaving speech untouched.

Gates clean up breaths, mouse clicks and room hiss between sentences, but a mis-set threshold chops quiet word endings — the telltale 'gated' sound. Modern AI noise suppression has replaced gating for many voice workflows.
