Using WebRTC + React + WebAudio To Create Spatial Audio

This tutorial demonstrates how to implement spatial audio in a WebRTC and React application using LiveKit, an open-source WebRTC SFU and client libraries. Spatial audio adjusts the volume of each participant's voice based on their direction and distance relative to the listener in a virtual world, providing immersion and context not possible with traditional audio apps. The tutorial covers the architecture of the app, the design of the API for spatial audio, and the implementation of the PannerNode from WebAudio to render audio spatially. A complete demo using this technique is available at spatial-audio-demo.livekit.io.
