TooB Noise Gate
A noise gate is an audio processing tool that controls the volume of an audio signal by allowing it to pass through only when it exceeds a set threshold. Signals below this threshold are muted or significantly reduced, effectively "gating" unwanted noise, such as background hum, hiss, or crosstalk, while preserving the desired sound, like vocals or instruments. The Hysteresis control sets a secondary threshold, slightly below the primary threshold, to determine when the gate closes. This creates a "buffer zone" to prevent the gate from rapidly toggling on and off (chattering) when the audio signal hovers near the primary threshold. For example, if the Threshold contol is set to -30dB and Hysteresis control is set to -5dB, the gate opens when the signal exceeds -30dB but only closes when it drops below -35 dB. This smoother transition ensures cleaner gating, especially for signals with fluctuating levels, like guitar.

The amount of attenuation applied when the gate is closed.
