Obstruction/Occlusion Tab

In the Obstruction/Occlusion tab of the Project Settings dialog box, you can enable and define the default volume, Low-Pass Filter (LPF), and High-Pass Filter (HPF) curves for obstruction and occlusion for each active platform in your project.

Interface Element	Description
(Platform list)	Specifies the platform for which you are defining obstruction or occlusion.
Obstruction/Occlusion
	Click the Configure Columns... shortcut (right-click) option from the column header band. The Configure Columns Dialog opens. Specify which columns to display and their order.
(Link/Unlink)	Displays whether the obstruction/occlusion curve is linked across all platforms.
Curve	Name of the obstruction/occlusion volume/LPF/HPF curve.
Use	Determines whether the curve is used in the project.
Notes	Additional information about the obstruction/occlusion volume/LPF/HPF curves in your project.
Graph view	A visual 2D representation of the volume and LPF attenuation curves. The X axis represents either occlusion or obstruction, and the Y axis represents either volume or LPF. The X axis is represented as a percentage from 0 to 100%. The Y axis is represented in decibels for volume, and percentage for LPF.
	Zooms in towards the center of the graph view.
	Resets the graph view to the default zoom factor ratio of 1:1.
	Zooms out from the center of the graph view.
Coordinates
X	The coordinate along the X axis of the selected control point. The X value represents the percentage of occlusion or obstruction. If more than one control point is selected, the field displays a value of 0, so that you can increase or decrease the value of all selected control points relative to their current values. For example, if you select two control points and type -5 in the X text box, both control points will move to the left by 5 units.
Y	The coordinate along the Y axis of the selected control point. The Y value represents the decibel volume or percentage LPF. If more than one control point is selected, the field displays a value of 0, so that you can increase or decrease the value of all selected control points relative to their current values. For example, if you select two control points and type -5 in the Y text box, both control points will move down by 5 units.
	Deletes all points for the selected curve except the first and last point.
