Mumble is a low-latency, high quality voice chat application intended for use alongside computer games.

Its primary features are:
• Very low latency.
• Denoising of audio.
• Automatic volume control so all players are equally loud.
• Unlimited number of channels with as deep a nesting as desired.
• Per-channel groups and access control lists.
• In-game overlay showing users status.

The design goal of mumble is to have audio quality just as good as if you were sitting in the same room, a goal that has largely been achieved. Current emphasis is on interchannel communication, to enable a mumble-connected community to work better than if they were in the same room.
