Mumble

Mumble is an open-source, low-latency voice-chat platform designed for clear, real-time communication.

Mumble uses the Opus codec and an efficient UDP protocol to deliver high-quality audio with minimal delay, even on slow connections.

It supports nested channels with fine-grained ACLs, positional audio for supported games, and automatic volume leveling to keep every participant equally audible. All traffic between client and server is protected by end-to-end encryption. An in-game overlay shows who is talking inside fullscreen games.
