Using the Voice Profiler

Now you can see the various properties affecting the heartbeat volume. What's even better is seeing exactly how these settings are controlling the heartbeat's volume in real time. This is accomplished in a layout called Voice Profiler.

  1. In the Wwise menu bar choose Layouts > Voice Profiler.


    The Voice Profiler layout contains a lot of different views. You may need to resize them to match the image below.

  2. In order for the Voice Inspector to work, you must enable Voice Inspector Data in the Profiler Settings.

  3. In the menu bar, choose Project > Profiler Settings.

  4. Select Voice Inspector Data and click OK.

  5. Click the Start Capture button.

    You see a yellow cursor move across the Voice Monitor graph at the bottom of the layout.

  6. Play the Heartbeat Sound SFX object.

    You'll see a line displayed that represents the volume the heartbeat is playing back at. As conditions change, you'll see the calculated value change.

  7. In the Transport Control, set the PlayerLife State to Alive and lower the RTPC for PlayerHealth to a value of 0.

    You see the line in the graph rise and you hear the heartbeat.

  8. In the Voice Explorer, click the Heartbeat row in the left-side pane.

    Now you can see a diagram showing the Sound SFX object represented by a rectangular box that displays current volume and filter values. It even shows you how the Heartbeat is routed through the Master Audio Bus. You'll learn more about audio bus routing later in the course.

  9. In the Transport Control, continue to adjust the PlayerLife state and the PlayerHealth RTPC.

    Notice that in the right pane of the Voice Inspector, a list indicates which features in Wwise are acting on the heartbeat's voice volume. These are known as 'drivers'. If you are ever playing a sound, but don't hear it, this is the perfect set of tools to help you discover exactly what's creating that circumstance.

  10. In the Transport Control view, stop the heartbeat, and then click the Stop Capture button.
