Spec score 8.0 #13 of 22 in Game Voice Chat Software

What it is

Mumble is free, open-source voice chat software for low-latency conversation and gaming. Communication is always encrypted, with public/private-key authentication enabled by default. In supported games, positional audio places voices within the game environment, while an overlay can show who is speaking, FPS, and the current time. Administrators manage users through an extensive access-control-list permission system. Ice protocols let server functions grow with web interfaces, authenticators, custom chat commands, and context-menu entries. The project supplies server software and supports self-hosting, describing low resource costs for hosting. Mumble lists gamers, podcast recorders, hobby radio users, and workplaces among its audiences. The core project uses a BSD-style free and open-source license. Official downloads cover Windows and macOS clients and servers; Linux users use distribution packages. iOS is marked unmaintained, last updated in 2017, while Android clients are third-party.
