Mumble-voip/mumble – Open Source voice-chat software – GitHub

Mumble is an open-source, low-latency, high-quality voice chat program written over Qt and Opus.

There are two modules in Mumble; the client (mumble) and the server (murmuring). The client works on Windows, Linux, FreeBSD, OpenBSD, and macOS, while the server should work on anything Qt can be installed on.

Note that by “Windows” we mean 7 and newer. Vista may be compatible, but we cannot guarantee it. If you don’t want to encounter potential problems, you can download Mumble 1.3.x, the latest version that provides support for XP.

Project documentation can be found on the wiki. Frequently asked questions can also be found there.

Example -extracts each time to check if there is an updated base image, then downloads and compiles the master branch

. You can also specify the user identifier (

UID) and group identifier (GID) for the murmurer user in the image. This allows users using link mount volumes to use the same UID/GID in the container as in the host
