Expander & Stereo Expander
An expander essentially "stretches" a signal's dynamic range, thereby reducing low-level
signals such as noise, effectively increasing the signal-to-noise ratio. Two expander
components are available: a single-channel Expander and a Stereo Expander. They can
be self-triggering or externally triggered via the sidechain input.
The Expander control window features a gain reduction (GR) meter, expander curve,
output level meter, and expander controls.
The Stereo Expander control window features a gain reduction (GR) meter, expander
curve, output level meters, and expander controls.
The gain reduction (GR) meter displays the amount of gain reduction being applied by
the Expander. The expander curve displays the effect of the Expander. The vertical axis
corresponds to the output signal level, while the horizontal axis corresponds to the
The Expander component features one input, one out-
put, and a sidechain input.
The Stereo Expander component features two inputs,
two outputs, and a sidechain input.
