Frequency Response (Panel)

Frequency Response (Panel)#

Frequency Response Panel.
The Frequency Response Panel plots the frequency response at points sampled along the audience for the selected array - one thin trace per sampled point, plus an energy-averaged mean curve. It replaces the Probes Panel found in earlier versions of System Optimiser.
The Frequency Response Panel is most useful for choosing the angles of a line array, in that the frequency response along the entire audience can be seen in one view quickly, without having to place multiple measurement microphones within the 3D View.
The Frequency Response Panel requires an open Sideview and follows its selected array. In the graph, only the selected array is taken into account (the array is soloed), all other sources are ignored (muted). That means the traces do not show any interaction between sources, and hence the Frequency Response Panel should not be confused with Microphones.

The Frequency Response Panel is part of the default 2D SOURCE layout, and can be opened from the panel add menu in the 3D SOURCES, 2D SOURCE or custom tabs.

In the header menu, the following options are available:

Average

Shows or hides the energy-averaged mean curve, plotted thick to make it stand out.

Window / Whole cut

Toggles between sampling only within the start/end coverage window set in the Sideview, and sampling the whole audience cut. The button’s label reflects the current state.

Autoscale

Re-fits the dB axis to the displayed traces.

Target Curve

In the controls strip beside the graph, a target curve can be selected and overlaid, with adjustable level and tolerance width. Choosing the Custom target opens an inline editor for your own target points, to describe the response you are aiming for.

Scroll to zoom the dB axis, drag to pan, and double-click to reset the view and re-fit the target level.

As with all Panels, the Frequency Response Panel can be resized and moved using Panel Drag & Drop, and ‘popped out’ into an additional System Optimiser window. The location of this Panel will be saved as part of the current tab.
