This tutorial guides users through building a VR chat application that enables spatial sound from speakers using an Oculus Quest headset. The project consists of four parts, including setting up the project with Oculus packages and Agora SDK, creating the scene, testing video streaming between VR and non-VR users, and discussing audio frame and audio source handling technology. The tutorial uses Unity Editor (version 2019 LTS) and an understanding of Unity's XR Framework as prerequisites.
