## Introduction
Mumble is an open-source voice over IP application focused on low-latency audio for gaming, team collaboration, and community voice channels. Its client-server architecture lets organizations self-host their own voice infrastructure with fine-grained permission controls.

## What Mumble Does
- Delivers low-latency voice communication optimized for real-time coordination
- Encrypts all voice traffic with TLS and OCB-AES128
- Supports hierarchical channel structures with per-channel permissions
- Provides positional audio for games that report 3D player coordinates
- Handles hundreds of simultaneous users on modest server hardware

## Architecture Overview
Mumble uses a client-server model where the server component (Murmur/mumble-server) manages channels, authentication, and audio mixing. Audio is encoded with the Opus codec at configurable bitrates and transmitted over a custom UDP protocol with TCP fallback. The protocol uses certificate-based authentication by default, with optional LDAP or database backends for user management.

## Self-Hosting & Configuration
- Deploy Murmur via package manager, Docker, or compiled binary
- Default port: 64738 (TCP+UDP); ensure both protocols are open
- Configure server settings in murmur.ini (bandwidth, welcome message, SSL certs)
- Set up ACLs (Access Control Lists) for channel-level permissions
- Supports Ice RPC interface for external administration tools

## Key Features
- Ultra-low latency audio with configurable quality settings
- Certificate-based authentication with optional password overlay
- Hierarchical channels with granular access control lists
- Overlay support for in-game HUD display of active speakers
- Cross-platform clients for Windows, macOS, Linux, iOS, and Android

## Comparison with Similar Tools
- **Discord** — feature-rich but closed-source, cloud-hosted, and collects user data
- **TeamSpeak** — proprietary with per-slot licensing costs
- **Jitsi Meet** — browser-based video/voice but higher latency for voice-only use
- **Matrix/Element (VoIP)** — general-purpose messaging with voice; not optimized for low-latency group voice
- **Revolt** — open-source Discord alternative but voice features are less mature

## FAQ
**Q:** How many users can a Mumble server handle?
A: A single Murmur instance can handle several hundred concurrent users on a standard VPS. Large deployments run thousands with proper bandwidth.

**Q:** Does Mumble support text chat?
A: Yes. Each channel has a text chat alongside voice. It also supports private messages and rich text with links and images.

**Q:** Can I integrate Mumble with game servers?
A: Yes. Mumble supports positional audio via a plugin system that reads player coordinates from supported games.

**Q:** Is there a web client?
A: Community-built web clients exist (such as mumble-web) but the native desktop client provides the best experience.
