T
he Vocalstrip Compander is a hybrid Compressor and Expander. Switch it on by clicking on the power button in its top left-
h
and corner.
Expander
First the signal enters a fixed ratio downwards expander, designed to reduce room
ambience, spill or breath noise that is often brought up by the subsequent
compression.
To set the level at which the level reduction is introduced, turn the Ex Thr (Expander
Threshold), located on the Compander’s right-hand side. Turn the threshold to
minimum to turn the expander off. The amount of level reduction introduced is
shown in the green bar to the left of the Ex Thr knob.
Compressor
The compressor offers both hard and soft knee
modes alongside fully variable Ratio, Thresh
(threshold), Attack, Releas (release) and
Makeup controls, along with a choice of Hard or
Soft Knee.
The output stage which is sourced after the
make-up gain features an optional Drive feature,
which introduces harmonic characteristics to the
signal. Its intensity is increase with the Makeup
gain. If you use a lot of make-up gain to drive the
circuit, the level can be reduced again using the
Output level control. The amount of level
reduction introduced is shown in the red bar to
the right of the compressor controls.
Compander Display
When any controls within the Compander section are moved, the
display in the top right-hand quarter of the window shows two
different graphs:
The left-hand graph is a gain-law display, showing the relationship between input and output levels,
as illustrated in the graph above-left.
The right-hand graph is an IO difference display, showing 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.
Note that the FFT controls are for the EQ display, not the Compander display.
Processing Order
The processing order is controlled at the base of the
plug-in window.
To move a module within the order, highlight it so that it is surrounded in yellow, and press either the left arrow or the
right arrow.
