I
nput and Output Sections
T
he input and output sections at either side of the plug-in window provide input and output gain control, along with displays
o
f the following information:
Compression Law Graph
The display in the centre of the plug-in window compares the input and output signals given the
current compressor settings. The thicker white line indicates the relationship between input
and output across the range of levels, while the faint line indicates a 1:1 relationship. In the
example to the right, an input level of –24dB results in an output level of –20dB (as this is below
the threshold, this indicates a Make-up gain of 4dB), while an input level of +6dB results in an
output level of –4dB.
Threshold and Ratio can be defined by moving the nodes within the display: Move the pink
node along its line to control the Threshold, and move the blue node up and down to control the
ratio.
Bleed Graph
The bleed graph indicates the frequencies which
are bypassing the compressor, as described on
the previous page.
I/O Diff Graph
The I/O Diff meter to the right of the Compression Law graph shows how often each level occurs within
the input and output signals. The input is shown on the left and the output on the right.
The vertical scale is amplitude, with 0dB at the top and –∞ at the bottom. The length of each line
protruding from the centre represents the number of incidents of that amplitude over a period of seconds.
In the graphic to the right, the input signal displays a mixture of very loud and very quiet, indicating that
the signal has a large dynamic range which is changing very quickly. The output signal indicates that this
dynamic range has been made smaller, with the loud bars being reduced in level and the quiet bars
being increased.
GR History
The GR History (Gain Reduction History) meter shows the current gain reduction and how it has fluctuating.
The thicker line towards the left of the display shows how much gain reduction is currently being used,
while the thinner lines to its right show how this has been changing over the past second.
Colour of knobs
You may also notice that the colour of the knob surrounds change to indicate
their level – green for low, yellow for mid, red for high.

Peak Meter
Allows you to observe the exact level at any point in
time. There are two meters in stereo and one in mono.
RMS Meter
The thinner bar to the right shows the
RMS (average) level over time.
Clip Light
Indicates that the signal is clipping. It clears after 1
s
econd, or click on it to clear manually.
R
ange Meter
The thin white bracket indicates the signal’s recent
dynamic range. Longer brackets indicate a larger
d
ynamic range. If the bracket edges are moving
quickly, this implies an ‘energetic’ signal.
