The effect of the Peak Detector settings is represented by the peak “blips” at the top of the dark orange peak level bars within
the
Expander Threshold meters in the Undo Meter window. Average levels are indicated by the bright orange bars.

Expander Levels Menu
The Expander Levels menu gives you access to the Relative Threshold, Band<Wideband Distance Limit, and Maximum Gain
controls of each band of Undo’s expanders.
♦
The Relative Threshold control for each band determines how far below the currently detected peak the expander
threshold sits. Lower thresholds (moving the slider to the right) result in a greater peak-to-threshold distance and
therefore provide more expansion. Higher thresholds (moving the slider to the left) narrow the peak-to-threshold
distance and provide less expansion.
♦
In addition to an adjustable per-band peak detector with adjustable attack and release speeds (whose function is
described above in the Peak Detector menu section), each channel also has a wideband peak detector with fixed attack
and release speeds. The
Band<WB Distance Limit controls determine the greatest distance by which an individual band’s
peak detector can fall relative to the wideband level and keeps any one band from being expanded if there are insufficient
levels to begin with. For example, if the current wideband peak is -6dB and this control is set to -10dB, the peak detector
for that individual band will not fall below -16dB.
♦
The Maximum Gain control sets the absolute maximum amount of gain that can be applied to the audio in each expander
band regardless of program material or any other control settings.
