How can I use head tracking for streaming?

You can stream to your audience and share the exact same audio that you are listening to, by configuring your streaming software. Whether you use Streamlabs, OBS, Twitch Studio, or any other option: you will need to configure the audio output to match Immerse Output device. When it comes to video, Immerse creates a virtual camera that can be selected on the streaming software and will allow you to use it as your webcam video.
