WebA noise gate is an audio processor that works to eliminate sounds below a given threshold in a recording. Noise gates are similar to compressors in that they both reduce the volume of audio. However, compressors work on audio signals that pass over the given threshold, whereas noise gates reduce signals that are under the given threshold.
