Profile Spatialized Audio
End-of-Life Notice for Oculus Spatializer Plugin
The Oculus Spatializer Plugin has been replaced by the Meta XR Audio SDK and is now in end-of-life stage. It will not receive any further support beyond v47. We strongly discourage its use. Please navigate to the Meta XR Audio SDK documentation for your specific engine:
- Meta XR Audio SDK for Unity Native
- Meta XR Audio SDK for FMOD and Unity
- Meta XR Audio SDK for Wwise and Unity
- Meta XR Audio SDK for Unreal Native
- Meta XR Audio SDK for FMOD and Unreal
- Meta XR Audio SDK for Wwise and Unreal
This documentation is no longer being updated and is subject for removal.
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.
Reading Profiler Analytics
  • OSP Version. The Oculus Audio SDK version of the connected OSP instance.
  • Spatialized Sounds. The number of spatialized sounds currently processed by the OSP.
  • Ambisonic Sounds. The number of ambisonic sounds currently processed by the OSP.
  • Reverb and Reflections. The current reverb and reflections parameter settings.
  • CPU %. Plots the estimated CPU usage of the process the OSP is running in. This is an estimated value and does not account for multi-processor architectures.
  • Processed Sounds. Plots the total number of spatialized and ambisonic sounds processed by the OSP.
