The side-chain is the signal path that a compressor uses to determine the amount of gain reduction it applies to the signal being compressed. This signal path is derived from the
input signal or
Key Input, depending on the user's selection.
When enabled, the Side-Chain EQ filter lets the user tailor the equalization of the side-chain signal so that the compression becomes frequency-sensitive.
Makes the compressor's detector less sensitive to low frequencies in the input signal or Key Input by rolling off at a rate of 6 dB per octave. For example, you might use this setting on a mix to prevent a bass guitar or bass drum from causing too much gain reduction.
Makes the compressor's detector more sensitive to mid-to high frequencies in the input signal or Key Input by boosting those frequencies in the side-chain signal. For example, you might use this setting to reduce sibilance in vocal tracks.
Enables the High Pass and peak settings simultaneously to make the compressor's detector more sensitive to high frequencies and less sensitive to low frequencies.
