Mumble uses the low- latency audio codec Opus as of version 1.2.4, the codec that succeeds the previous defaults Speex and CELT. The system supports many usage scenarios, at the cost of added configuration complexity. Each channel has an associated set of groups and access control lists which control user permissions. It also matches team-based first-person shooter (FPS) games. This is useful during larger events where a small group of users may be chatting in a channel, but are linked to a common channel with other users to hear announcements. Users can temporarily connect channels to create larger virtual channels. Channel hierarchy Ī Mumble server (called Murmur) has a root channel and a hierarchical tree of channels beneath it. Mumble is free and open-source software, is cross-platform, and is released under the terms of the BSD-3-Clause license.
