Understanding property filter behavior (LPF, HPF)
The cumulative behavior of filter properties, such as Low-pass filter and High-pass

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.
