Profiling Audio Objects

Profiling in Wwise allows you to monitor the state of Audio Objects as they pass through the bus pipeline. It provides detailed information about Audio Objects, such as their spread, Metadata, metering, and position relative to their listener position and orientation.

  1. If authoring on Windows, enable Windows Sonic. This establishes a spatial audio endpoint that can receive and process Audio Objects from Wwise.

  2. From the Wwise menu bar, select Audio > Authoring Audio Preferences....

    The Authoring Audio Preferences dialog opens.

  3. In the Authoring Audio Preferences dialog, select Enable System Audio Objects.

    [Note] Note

    To profile Audio Objects played through Wwise Authoring, as opposed to from a game engine, System Audio Objects must be enabled for use by Wwise.

  4. In the Audio tab of the Project Explorer, double-click the System Audio Device.

    The System Audio Device Editor opens.

  5. In the System Audio Device Editor, select Allow 3D Audio. This gives permission to the Audio Device to attempt to activate the 3D Audio features of the endpoint.

    [Note] Note

    Selecting this option is not a guarantee that 3D audio will be activated; 3D audio is only activated if the platform supports it. Refer to Audio Device Editor: System for details on the other elements in this view.

  6. Open the Property Editor for the sound you would like to profile. Select the Positioning tab and do the following:

    • Set 3D Spatialization to Position.

    • Set 3D Position to Emitter with Automation.

    • Select the Automation... button. The Position Editor (3D Automation) view opens.

    [Note] Note

    Assigning a 3D position to sounds allows for the display of Audio Objects in relation to the listener in the Audio Object 3D Viewer.

  7. In the Position Editor (3D Automation) view, select the New button.

    A path is created, offset from the origin.

  8. From the menu bar, select Layouts > Audio Object Profiler.

    The Audio Object Profiler layout opens.

  9. In the Audio Object List view at the upper-left corner of the layout, select the View Settings button.

    The Profiler Settings dialog opens.

  10. In the Profiler Settings dialog, select the Audio Object Data and Voices Data options.

  11. Select the Start Capture button to begin capturing profiler data.

  12. From the menu bar select Views > Transport Control and then play the sound you would like to profile.

  13. In the Voice Monitor view at the bottom of the layout, drag the time cursor (yellow line) to the left until you see the sound in the list.

    At this point, the Audio Object is displayed in the Audio Object List view and Audio Object 3D Viewer.

  14. Select the sound in the Audio Object List view.

    Both the Audio Object Metadata view and the Audio Object Meter view display data corresponding to the selected Audio Object.
