Limiter

UI Element	Purpose
Input node	Connection point for wiring input to the Limiter block
Side-chain node	The side-chain detects the incoming signal level and calculates the correct gain to apply to the input signal. The side-chain has a separate input, allowing external processing when desired. When not externally wired, the side-chain connects internally to the main input.
Output node	Connection point for wiring the Limiter output to another block

UI Element	Purpose
Response graph/meter	Graphical representation of the signal. Use the green handles to coarsely adjust Threshold. A real-time side-chain meter shows the gain reduction relative to Threshold with a gain reduction meter on top in dB. The meter accurately follows the attack and release rate of limiting.
Threshold	Represents the side-chain level in dBFS above which signals are limited. The graphic displays side-chain input in dBFS on the x-axis and output level on the y-axis for any side-chain input level between 0 dBFS and -100 dBFS. The threshold is the point at which additional input does not result in increasing output.
Attack	Determines how fast the Limiter responds to increases in gain reduction. The set value describes how long it takes a step to settle to within 95% of the final value.
Release	Determines how fast the Limiter responds to decreases in gain reduction. The value describes the time required for a 10 dB step to settle to within 95% of the final value.
Auto Mode	Selecting Auto Mode provides instantaneous attack and a release time dependent on side-chain level history.
Bypass	Checking the Bypass checkbox turns the Limiter block into a straight-through wire, although the side-chain meter continues to function. Yellow bars in the Processing Map indicate a bypass.

Response graph/meter

Graphical representation of the signal. Use the green handles to coarsely adjust Threshold. A real-time side-chain meter shows the gain reduction relative to Threshold with a gain reduction meter on top in dB. The meter accurately follows the attack and release rate of limiting.

Threshold

Represents the side-chain level in dBFS above which signals are limited. The graphic displays side-chain input in dBFS on the x-axis and output level on the y-axis for any side-chain input level between 0 dBFS and -100 dBFS. The threshold is the point at which additional input does not result in increasing output.

Attack

Determines how fast the Limiter responds to increases in gain reduction. The set value describes how long it takes a step to settle to within 95% of the final value.

Release

Determines how fast the Limiter responds to decreases in gain reduction. The value describes the time required for a 10 dB step to settle to within 95% of the final value.

Auto Mode

Selecting Auto Mode provides instantaneous attack and a release time dependent on side-chain level history.

Bypass

Checking the Bypass checkbox turns the Limiter block into a straight-through wire, although the side-chain meter continues to function. Yellow bars in the Processing Map indicate a bypass.
