You can profile local or remote apps with the Oculus Audio Profiler tool.

Profiling Local Apps

To connect the profiler to a local app:
  1. Start your app.
  2. Start OculusAudioProfiler.exe.
  3. Click Connect.

Profiling Remote Apps

Your app must be running on the same local area network as the computer running the Oculus Audio SDK Profiler. Additionally:
  • Windows apps must have the Oculus Audio Profiler port allowed in the Windows Firewall. The default port is 2121.
  • Mobile devices must be placed into Wi-Fi debugging mode. See Connecting adb via WIFI
To connect the profiler to a remote app:
  1. Obtain the IP address of the device running your app.
  2. Start your app.
  3. Start OculusAudioProfiler.exe.
  4. Enter the IP address and port of the device. The default port is 2121.
  5. Click Connect.
If you cannot connect to your remote app, try these troubleshooting tips:
  • Make sure the port you are using is not blocked by your network settings or Windows Firewall.
  • Make sure your computer and remote device are on the same LAN and subnet.
  • If connecting to Meta Quest or other mobile Android devices, try to connect the PC to the network over Wi-Fi so that both the device and the PC are connected to the same Wi-Fi network.
