Hey there! Just wanted to share how LiveKit handles media over WebSocket in a few key situations: • Track Egress: Audio can be sent over WebSocket as raw PCM (

pcm_s16le

) using binary frames. Plus, you'll get JSON notifications whenever there's a change in track state, like mute or unmute. • Agents Framework: Here, WebSocket helps with server-to-server chats, like with OpenAI's Realtime API. But when it comes to sending media to users, LiveKit switches to WebRTC to keep things smooth and fast. • Client SDKs: WebSocket is great for signaling and sending data, but it’s not the main way media gets delivered to end-users. So, for most media streaming—especially video—LiveKit relies on WebRTC to make sure you get low latency and top-notch performance. Hope this clarifies things!
