Gate

Gating, or noise gating, silences audio signals below a set threshold. As soon as the signal level exceeds the threshold, the gate opens to let the signal through.

Attack (0.1 to 1000 ms): Sets the time after which the gate opens when it is triggered.

Note
Deactivate the Live button to make sure that the gate is already open when a signal above the threshold is played back.
Hold (0 to 2000 ms): Determines how long the gate remains open after the signal drops below the threshold level.
Release (10 to 1000 ms or Auto mode): Sets the time after which the gate closes (after the set Hold time). If Auto Release is activated, Gate automatically finds the best release setting for the audio material.
Threshold (-60 to 0 dB): Determines the level where the gate is activated. Signal levels above the set threshold trigger the gate to open, and signal levels below the set threshold close the gate.
State LED: Indicates whether the gate is open (LED lights up in green), closed (LED lights up in red) or in an intermediate state (LED lights up in yellow).
Analysis (Pure Peak to Pure RMS): Determines whether the input signal is analyzed according to peak or RMS values, or a mixture of both. A value of 0 is pure peak and 100 pure RMS. RMS mode operates using the average power of the audio signal as a basis, whereas Peak mode operates more on peak levels. As a general guideline, RMS mode works better on material with few transients such as vocals, and Peak mode works better for percussive material with a lot of transient peaks.
Live: If this button is activated, the look-ahead feature of the effect is deactivated. Look-ahead produces more accurate processing, but adds a specific amount of latency as a trade-off. If Live mode is activated, there is no latency, which is better for live processing.

Side-Chain Section

Side-Chain: Activates the internal side-chain filter. The input signal can then be shaped according to the filter parameters. Internal side-chaining is useful for tailoring how the gate operates.
Monitor: Allows you to monitor the filtered signal.
Center (50 to 20000 Hz): If the Side-Chain button is activated, this sets the center frequency of the filter.
Q-Factor: If the Side-Chain button is activated, this sets the resonance or width of the filter.
Filter buttons (Low-Pass/Band-Pass/High-Pass): If the Side-Chain button is activated, you can use these buttons to set the filter type to low-pass, band-pass, or high-pass.
