## What it is
Mumble is an open-source, low-latency, high-quality voice chat application built on Qt and Opus, consisting of a client and a self-hostable server (mumble-server, formerly murmur). It supports positional audio, multi-channel recording, granular permissions, and a plugin system.

## Use cases
- voice chat for gaming with low latency
- self-host a private voice server for a community
- record podcasts with multi-channel audio
- positional audio in games
- voice communication for large online communities
- workplace voice conferencing without third-party services

## When to choose
- you need very low latency voice communication
- you want to self-host your own voice chat server
- you need positional audio or fine-grained permission control
- you run a large community with hundreds of simultaneous speakers

## When to avoid
- you want a hosted, zero-setup solution like Discord
- you need built-in video or screen sharing
- you want a modern web-based client without installing software
