CHAPTER 20. LIVE AUDIO EFFECT REFERENCE 263
The Threshold slider sets the gate's sensitivity. If the gate is open and passing signal (i.e.,
the signal exceeds the gate threshold), the green LED lights.
The Floor parameter, located beneath the Threshold fader, can allow attenuating signals
below the threshold rather than just cutting them off. If set to -inf dB, a closed gate will
mute the input signal. A setting of 0.00 dB means that even if the gate is closed, there is
no effect on the signal. Settings in between these two extremes attenuate the input to a
greater or lesser degree when the gate is closed.
The Attack time determines how long it takes for the gate to switch from closed to open
when a signal goes from below to above the threshold. Very short attack times can produce
sharp clicking sounds, while long times soften the sound's attack.
When the signal goes from above to below the threshold, the Hold time kicks in. (Note
to tech heads: the gate has hysteresis, so the release occurs about 3 dB lower than the
threshold.) After the hold time expires, the gate closes over a period of time set by the
Release parameter.
20.14 Grain Delay
The Grain Delay Effect.
The Grain Delay effect slices the input signal into tiny particles (called grains) that are then
individually delayed and can also have different pitches compared to the original signal
source. Randomizing pitch and delay time can create complex masses of sound and rhythm
that seem to bear little relationship to the source. This can be very useful in creating new
