The cumulative behavior of filter properties, such as Low-pass filter and High-pass filter, can be set to one of two possible methods:
Sum All Values: The property values are accumulated via addition.
Use Highest Value: The property values are accumulated by retaining the highest value.
The filter behavior is defined for the entire project, and applies to the properties listed below.
Low-pass filter.
High-pass filter.
Output Bus Low-pass filter.
Output Bus High-pass filter.
User-defined Auxiliary LPF 0.
User-defined Auxiliary LPF 1.
User-defined Auxiliary LPF 2.
User-defined Auxiliary LPF 3.
Game-defined Auxiliary Sends LPF.
User-defined Auxiliary HPF 0.
User-defined Auxiliary HPF 1.
User-defined Auxiliary HPF 2.
User-defined Auxiliary HPF 3.
Game-defined Auxiliary Sends HPF.
To configure your project's filter behavior, refer to Configuring filter behavior.
The illustration below demonstrates how the property values are accumulated within the project hierarchy.
Filter accumulation methods. In this example, each object specifies a value for the Low-pass filter property. The Low-pass filter value applied to the sound depends on the accumulation method. | |
Sum All Values. The Low-pass filter property values of each object are summed. | |
Use Highest Value. The highest of all of the object Low-pass filter properties is used. |
The filter behavior is specified via the Project Settings.

When changing the filter behavior, Wwise will:
The changes to the Work Units cannot be undone. Ensure that you have a saved copy of your project before changing the filter behavior, if you want to revert later on. |
To configure the filter behavior:
Open the Project Settings dialog by doing one of the following:
From the Project menu, select Project Settings.
Press Shift+K.
Switch to the General tab.
In the Filter Behavior group, select the desired filter behavior:
Sum All Values (Default). Filter property values are summed.
Use Highest Value. Filter property values are maxed.
Click OK to apply the settings.
