Parameter Description
Levels panel
Input/Output level meters Show peak signal levels before and after processing.
• Green indicates nominal levels
• Yellow indicates pre-clipping levels, starting at –6 dB below full scale
• Red Indicates full scale levels (clipping)
n
Unlike scales on analog compressors, metering scales on a digital device
reflect a 0 dB value that indicates full scale (fs)—the full-code signal level.
There is no headroom above 0 dB.
The clip indicators at the top of the Output meters indicate clipping at the input or
output stage of the plug-in. Click an indicator to clear it.
Gain Reduction meter
(GR)
Indicates the amount the input signal is attenuated (in dB) and shows different
colors during de-essing.
• Light orange indicates that gain reduction is being applied, but has not reached
the maximum level set by the Range control
• Dark orange indicates that gain reduction has reached the maximum level set by
the Range control
Options panel
HF Only button When this button is enabled, gain reduction is applied only to the active frequency
band set by the Frequency control. When this button is disabled, the De-Esser
applies gain reduction to the entire signal.
Listen button When this button is enabled, you monitor the sibilant peaks used by the De-Esser as
a side-chain to trigger compression. This is useful for listening only to the sibilance
for fine-tuning De-Esser controls. To monitor the whole output signal without this
filtering, deselect the Listen button.
Graph display Shows a curve that represents the level of gain reduction (on the y–axis) for the
range of the output signal’s frequency (on the x–axis). The white line represents the
current Frequency setting, and the animated orange line represents the level of gain
reduction being applied to the signal. Use this graph as a visual guideline to see
how much dynamics processing you are applying at different points in the
frequency spectrum.
