Real-time audio and video in the Metaverse

The article discusses the integration of real-time audio and video features into Unity WebGL applications for browser-based metaverse projects. It explains how developers can leverage LiveKit's Unity WebGL SDK to manage game state within the Unity/C# execution environment while using separate JavaScript code to utilize the browser's WebRTC implementation for audio and video. The article also highlights the challenges faced in developing this bridge, such as maintaining state on the JS side and bridging textures from the browser to Unity. Furthermore, it provides a sample application that showcases the power of LiveKit's Unity WebGL SDK by rendering each player's camera feed as cyberpunk-style interlaced video with spatial audio for communication. The article concludes by encouraging developers to explore building virtual worlds and rich 3D spaces using this technology.
