Mumble review

Mumble is the free, open source answer for groups that only need voice and are comfortable running a server. The project describes it as low latency, high quality voice chat, with encryption always on and public and private key authentication by default. Gamers get an in-game overlay that shows who is talking and positional audio that places voices where players stand in the game. Administrators get an extensive access control system, Ice protocol APIs for scripts and bots, web interfaces and authenticators that tie logins to an existing user database. The project says EVE Online groups run more than 100 simultaneous speakers on it. The weak points are polish and mobile: setup is manual, the interface looks dated next to Discord, Android use relies on third-party apps, and the official iOS app has not been updated since 2017. It is a voice tool, not a full community hub.
