Audio Bus tab and Auxiliary Bus tab: busses

In the Audio Bus or Auxiliary Bus tab, there is a bus meter (if processing), bus status information, and the HDR Window (if HDR is enabled for the bus).

Bus Specific

Interface Element

Description

(Meter)

A per channel peak meter. For more information about speaker configurations and channels, refer to Understanding Bus Configurations.

The signal level is green under -6 dB, yellow from -6 to 0 dB, and red over 0 dB.

The meter data source can be synchronized with the currently playing objects or, when a profiling session is present, with historical values. When the meter is showing the profiling session history, use the LIVE button on the Wwise toolbar to return to current values.

[Note]Note

Meters are not available on non-mixing busses. Refer to Understanding the bus icons and processing status for more information on the various processing statuses.

Bus Status (Authoring)

Interface Element

Description

Processing

Displays the processing status of the bus based on how the project has been authored in Wwise; the processing status at runtime may differ. Refer to Understanding the bus icons and processing status for details on how the processing status is determined.

Bus Config.

Displays the bus configuration at the Pre-Effects stage based on how the project has been authored in Wwise; the bus configuration at runtime may differ.

The displayed value is read-only. You can change it with the Configuration property in the Property Editor for the selected Audio Bus or Auxiliary Bus. See Property Editor: Audio Bus or Property Editor: Auxiliary Busses.

When there is mixing on a bus, the Pre-Effects stage is after the mixing stage, but before any Effects are processed. For example, in the case of a bus with the bus configuration set to 2.0, all inputs are mixed to a stereo configuration, and then Effects are added to the stereo signal. The Bus Config. field displays the configuration of the bus between these two stages.

Out Config.

Displays the bus configuration at the Post-Effects stage (i.e., after both mixing and Effects have been processed). This is based on how the project has been authored in Wwise; the bus configuration at runtime may differ.

Because Effects have the ability to change the bus configuration, the Out Config. can differ from the Bus Config. For example, consider a bus with the Reflect plug-in. The Bus Config. could be 1.0, while its Out Config. would be Audio Objects.

If there are no Effects inserted on a bus, Bus Config. and Out Config. are equivalent. When there are Effects inserted on a bus, the Out Config. will indicate 'Unknown' unless you are profiling captured data from the sound engine. In this case, the actual Out Config. will be displayed.

HDR

Interface Element

Description

HDR Window

Displays the applicable HDR threshold dB range as a light blue rectangle within a full window range of -96 dB to 96 dB. Only visible when the bus is HDR enabled. See Enabling HDR in your project.
