Expander Module

The Expander is part of the DrawmerECL plug-
in and is modelled on the Drawmer DL241 and
DS201 hardware processors.
Features
Auto-adaptive attack and release for a more
musical response
Upward expansion capability with a wide
Threshold
Adjustable Ratio with soft-knee options
Gain reduction LED metering
Expander
A common problem with compression is that
maximum gain compensation occurs during ex-
tremely quiet passages or during pauses. This re-
sults in an increase of background noise, the de-
gree of which depends on the amount of
compression applied.
The accepted way of dealing with this problem
is to use an Expander for low-level gating that
keeps quiet passages or pauses in the material
clean. A problem with simple expanders is that
they may undesirably process low-level audio
signals, since the expander has no way of differ-
entiating low-level audio signals from noise.
On a vocal track, for example, this can lead to
the start or ending of words being accidentally
removed, especially if the singer has a wide dy-
namic range.
