Understanding the Profiler

To assist you with information, the Wwise Profiler is divided into three sections/panels. Each one is connected and relies on the others, so when troubleshooting you’ll frequently switch between them. You should already be familiar with the profiler from previous certifications, but here’s a rundown of relevant learnings for this certification.

  • Capture Log: A log of information about all activities in the sound engine.

  • Advanced Profiler: A very detailed overview of sound engine information, from SoundBank memory sizes to your node-based structure of active Events.

    All information in this window is a generated snapshot from a given frame, meaning that the information you get is what happens in this exact frame. By moving the time cursor in the Performance Monitor, the information gets updated with the selected frame.

  • Performance Monitor: A monitor with color-coded graph for (among other things) CPU, memory, and bandwidth over time.

    In the graph view, a Performance Monitor time cursor will determine what you’ll see in the Advanced Profiler. If you notice any sudden resource overload in the Performance Monitor, you can drag the time cursor onto that frame and continue your investigations in the Advanced Profiler or Capture Log.


The graphs and the list view can be customized to what you’re currently looking for.

  1. Select the View Settings option in the right corner of the Performance Monitor view.

  2. In the Performance Monitor Settings view’s Show in Graph column, make sure the following are selected:

    • CPU - Total

    • Number of Voices (Physical)

    • Number of Voices (Total)

    • Output Peak

    • Total Streaming Bandwidth (Low-Level)

    • Total Used Memory


    Setting a value higher than 0 in the Moving Avg column overlays an average curve on top of the original graph curve. This is especially useful when monitoring data that fluctuates rapidly like CPU or Streaming Bandwidth for example.

With these options selected, you’ll have a good variety of informative curves for the upcoming lesson exercises.
