Dynamics Knee
Figure 17.14: Dynamics Knee
Multiband Expander contains a Dynamics Knee diagram for each compressor processing section. The diagram
provides feedback on the response of the associated dynamics processor. Both the horizontal and vertical axes
are calibrated in dBFS. The horizontal axis corresponds to the input level and the vertical axis represents the
output level. The heavy line shows the dynamic of the associated processing block. This means that if you
sent in a sine wave at a given input level, the output level would be equal to the level shown on the graph.
When the processor is working with real dynamic signals, the graph is a good approximation of the response
when the attack is fast and the release is slow.
In most cases, however, the dynamic response of the processor will not match its static response. In order to
represent this, we have included a “bouncing ball” meter for both the gate and the compressor. This metering
is shown as a red circle that is overlaid on the knee diagram. The red circle is placed so its horizontal position is
equal to the instantaneous input level and its vertical level is equal to the instantaneous output level. Examining
this meter while you are adjusting the dynamics controls will provide you with a great deal of information
about how the processor is operating and how the controls interact.
