Use the Noise Gate to reduce the level of sound below a specified threshold level.
Noise Gates may be used to cut the level of residual noise between sections of a recording. While this is essentially a very simple effect, this Noise Gate has a number of features and settings that allow it to be both effective and unobtrusive and well suited to most types of audio.
