What Mumble is

Mumble is free, open-source voice chat software for low-latency conversation and gaming. It states that communications are always encrypted, with public/private-key authentication enabled by default. In supported games, positional audio places voices in context; an in-game overlay can show who is speaking, FPS, and the current time. Server administrators can manage users with an extensive access-control-list permission system. Ice protocols let server functionality be extended with features such as web interfaces, authenticators, custom chat commands, and context-menu entries. The project provides server software and supports self-hosting. Mumble describes use by gamers, podcast recorders, hobby radio users, and workplaces. Its core project uses a BSD-style free and open-source license. Official downloads list Windows and macOS clients and servers, while Linux users are directed to distribution packages. The iOS app is marked unmaintained and was last updated in 2017; listed Android clients are third-party apps that Mumble does not control or maintain.
