Wwise Fundamentals

From the menu bar, click Layouts > Voice Profiler.

The Voice Inspector layout opens, but to use it, you must first enable Voice Inspector Data.

Click the gear button (Alt+G).

In the Profiler Settings dialog that opens, select Voice Inspector Data and click OK.

The Voice Profiler layout doesn't include the Transport Control. You'll need it for this exercise, so you'll add it to the layout making use of the skill you learned in the last exercise.

From the menu bar, click Views > Transport Control (Shift+T).

The Transport Control view opens in a floating window.

Drag the Heartbeat - Transport Control tab onto the main Wwise window. As you drag, possible docking locations are indicated in blue. Release the tab below the Voice Explorer view as shown. Then drag the dividers between the views and panes to resize them as necessary.

Click the Start Capture button.

A yellow cursor moves across the Voice Monitor graph at the bottom of the layout.

In the Transport Control, click the Play button (Spacebar) to play the Heartbeat sound.

At this point, you won't hear the heartbeat and you won't see any change in the Voice Monitor graph either. This is because of the volume curve configured in Module 5: Using Game Parameters. According to that curve, when PlayerHealth is between 50 and 100, the volume of the heartbeat is -200dB, which is inaudible. When PlayerHealth goes below 50, the volume of the heartbeat gradually increases toward 0dB.

Now you're going to use the Transport Control to audition what it sounds like when the player is alive and their health goes below 50.

In the Transport Control, set the PlayerLife State to Alive.

Select the Display RTPCs button.

While watching the Voice Monitor graph, slowly lower the RTPC for PlayerHealth to a value of 0 .

When PlayerHealth goes below 50, the line in the graph rises and you start to hear the heartbeat. Note, the shape of the curve varies depending how quickly you lower PlayerHealth.

In the Voice Explorer, select the Heartbeat row.

In the left pane of the Voice Inspector, you now see a diagram showing the Sound SFX object represented by a rectangular box that displays current volume and filter values.

	The diagram also shows you that the Heartbeat is routed through the Master Audio Bus. You can learn about audio bus routing in Module 12: Understanding the Master Audio Bus.

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 affecting the heartbeat's voice volume. These are known as drivers. If you are ever playing a sound but don't hear it, this set of tools will help you discover the cause.

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