between displaying the Time (attack and release), Below (threshold and ratio) and Above
(threshold and ratio) for each band.
For the Above thresholds, Attack de nes how long it takes to reach maximum compression
or expansion once a signal exceeds the threshold, while Release sets how long it takes for
the device to return to normal operation after the signal falls below the threshold.
For the Below thresholds, Attack de nes how long it takes to reach maximum compression
or expansion once a signal drops below the threshold, while Release sets how long it takes
for the device to return to normal operation after the signal goes above the threshold.
With Soft Knee enabled, compression or expansion begins gradually as the threshold is
approached.
The RMS/Peak switch also affects how quickly Multiband Dynamics responds to level
changes. With Peak selected, the device reacts to short peaks within a signal. RMS mode
causes it to be less sensitive to very short peaks and to begin processing only when the
incoming level has crossed the threshold for a slightly longer time.
The global Output knob adjusts the overall output gain of the device.
The Time control scales the durations of all of the Attack and Release controls. This allows
you to maintain the same relative envelope times, but make them all faster or slower by the
same amount.
The Amount knob adjusts the intensity of the compression or expansion applied to all bands.
At 0%, each compressor/expander has an effective ratio of 1, meaning that it has no effect
on the signal.

Multiband Dynamics Tips
Multiband Dynamics is a feature-rich and powerful device, capable of up to six independent
types of simultaneous processing. Because of this, getting started can be a bit intimidating.
Here are some real-world applications to give you some ideas.
