Noise Gate

Designed to remove unwanted noise or sound from an audio signal.

This could be:

• Gaps in vocal phrases.

• Breaths.

• String buzz.

• Bleed from other instruments.

Threshold.

Reduction.

Attack.

Release.

This is the amount (dB) that the noise gate will turn down the incoming signal once it falls below the threshold.

This allows you to control how severe the noise gate reduction is.

Serves the opposite function as it does on a compressor.

When the incoming signal falls below the threshold, the noise gate will turn down the signal.

This is the speed at which the noise gate will start to open once the signal passes the threshold.

• Fast attack: the noise gate will open almost immediately.

• Slow attack: the noise gate will take longer to respond to opening creating a smoother transition.

This is the speed at which the noise gate will start to close once the signal has fallen below the threshold.

• Fast release: the noise will close almost immediately and return to the level set by the amount of reduction.

• Slow release: the noise gate will take much longer to close and reach the level set by the amount of reduction.

Refers to any unwanted sound captured by a microphone when recording.

For example: kick drum sound in the snare drum microphone.
