Gate

The Gate is a device used to block audio signals that are below the threshold value. Only when levels are above the threshold can they be heard. Commonly used to clean unwanted audio in recordings, such as hi hat leakage in a snare drum track.

THRESHOLD
Set the level the detector signal must go above for the Gate to start opening and let audio pass through. When the detector signal is below the threshold audio is blocked. Only signals above the threshold will pass through the gate. If ‘hysteresis’ is at 0, the gate will begin to close again when the detector signal falls below the threshold.

HYSTERESIS
Set the level the detector signal must fall to for the Gate to start closing and block audio. If hysteresis is less than 0, the Gate will start to close again when detector signals fall below the sum of the threshold and hysteresis levels. This is useful to avoid rapid engagement and disengagement of the Gate when signals fluctuate around the threshold.

ATTACK
In the Gate device, attack is a meta control that controls both the detector attack time and the time it takes for the Gate to fully open when signals are above the threshold.

ATT CURVE
Changes the curve of the Gate opening. A value of 0 results in a linear curve, while negative values result are increasingly more concave and positive values are increasingly convex.

RELEASE
In the Gate device, release is a meta control that controls both the detector release time and the time it takes for the Gate to fully close after signals falls below the threshold.

REL CURVE
Changes the curve of the closing of the Gate. A value of 0 results in a linear curve, while negative values result are increasingly more concave and positive values are increasingly convex.
