Mumble is voice communication software designed to bring a group of users together in a room. The software was designed mainly for interactive gaming but it can also be used by businesses and corporations to hold off-site meetings. Mumble is similar to popular VOIP programs such as Ventrilo and TeamSpeak but with lower latency and innovative features such as live overlay and positional sound.
The Mumble client software runs on all the major operating systems including Windows, Mac OS X and Linux.
The Mumble client will run on any modern computer with a working sound card and microphone. Mumble uses an extremely small amount of bandwidth; any DSL or cable modem internet connection is capable of handling its use.
Mumble uses DirectSound 3D technology to adjust a gamers volume depending on their position in a game. For example, if Gamer A is standing directly next to Gamer B while in-game, their voices will be louder to one another. If Gamer C is across the map from Gamers A and B, Gamer C will sound much softer or more distant to Gamers A and B.
Mumble is open source technology developed and maintained by a larger community of developers. The software project can be found on their website http://mumble.sourceforge.net/
