Highlights
- Low-latency voice chat over the Opus codec, with push-to-talk or voice activation, noise suppression and echo cancellation.
- Connects to a server the community runs itself; channels form a tree with per-channel access control lists and groups.
- Positional audio places other voices by their location in supported games, with an overlay showing who is speaking.
- Users are identified by a client-held certificate rather than by a password, and client-server traffic is encrypted.
- Text chat exists alongside voice, but there is no offline message history to catch up on after reconnecting.
About this application
Mumble is a voice chat client built around keeping the delay between speaking and being heard short enough for coordination during games or live work. It connects to a server program that a community runs for itself rather than to a hosted service, so a group provides its own infrastructure and controls who may join.
A server is organised as a tree of channels. Moving into a channel means hearing and being heard by the people in it, and access is governed per channel by access control lists and groups. Audio is carried with the Opus codec, using push-to-talk or voice activation, with adjustable noise suppression and echo cancellation. Positional audio places other players' voices according to where they are in supported games, and an overlay can draw who is currently speaking on top of a full-screen game.
Traffic between client and server is encrypted, and users are identified by a certificate held in the client rather than by a password. Text messages can be sent alongside voice, but Mumble is not a general messenger: there is no offline history to catch up on after reconnecting.
