Mumble is a voice chat application designed for group communication with minimal delay. It is particularly popular among gamers, but its combination of audio quality, privacy and server administration facilities also makes it useful for communities, clubs and remote teams.
Mumble follows a client/server model. Users connect to a server and communicate within channels, while administrators determine who can enter, speak or perform management functions. The server component, commonly known as Murmur, can be hosted independently, giving organisations control over their own voice communication infrastructure.
The application prioritises responsive audio rather than general-purpose messaging or video conferencing. Its desktop client provides tools for managing input devices, controlling voice activation and identifying participants without leaving a game or other application.
This is free and open source software.
Key Features
