SONAR processes the audio as directed.
Attack Time (ms) The value in this field is the interval of time after the volume reaches the Open Level
for the gate to fully open. Opening the gate gradually produces a fade-in effect
instead of an instant on-off sound.
Hold Time (ms) The minimum time for the gate to stay open. Hold Time is useful when you’ve set
high open and close levels, for example, when your source signal is very loud. Noise
gates set this way tend to react to repeated percussive passages (such as drum
rolls) by repeatedly opening and closing; this can sound unpleasant. By setting a
hold time, you can ensure that the gate stays open long enough during percussive
passages.
Release Time (ms) The amount of time after the Close Level is reached that the gate actually closes.
This lets the tail end of sounds pass through without being clipped.
Look Ahead (ms) The value in this field causes the gate to open slightly before the sound reaches the
Open Level so you don’t lose the sound’s attack.
