What Is a Noise Gate?

A Noise Gate is a must-have device for any audio engineer. Whether you're mixing live sound or running a recording studio, a Noise Gate can help you acquire the perfect volume level and mix of any vocal or instrumental track or signal.

Definition

A Noise Gate is an electronic device or software logic used to control an audio signal's volume. It's used in recording and live sound to control the volume level of any audio signal--from a microphone, audio or instrument.

Function

A Noise Gate only allows frequencies to pass through to the speakers if they are above a certain volume level. If they're below the set level, the signal doesn't pass to the speakers.

Types

A Noise Gate can be a physical device that's run through recording equipment, or it can be software that's run by a program such as Pro Tools.

Famous Ties

One of the most well-known uses of a Noise Gate is the audio effect added to the vocals at the beginning of Phil Collins' hit song "In the Air Tonight."

Fun Fact

Godley & Creme used a Noise Gate to re-create the sounds of a burning brushfire for their song "Fire" on the album "Consequences."
