A new NoiseGate module

Added a NoiseGate module. With the Attack and Release controls you set the attack and release times.


Reworked the noise gate a bit to have a threshold and a ratio control. It can now completely close the gate (and the above image had been changed for this).

The Threshold control sets the signal level for the gate to open and close. Once the signal goes above the Threshold level the gate will open with the Attack curve, once it goes below the Threshold it will close with the Release curve. The ratio control sets the amount of the effect, totally to the right means that there is no gating and when set totally to the left the gate will be fully closed for signals below the threshold value.
