Mumble is an Open Source, low-latency and high-quality voice-chat program written on top of Qt and Opus.
There are two modules in Mumble; the client (mumble) and the server (mumble-server formerly known as murmur). The client works on Windows, Linux, FreeBSD, OpenBSD, and macOS, while the server should work on anything Qt can be installed on.
