OpenSpeak - Open Source Voice Communication Platform

An open-source TeamSpeak alternative built in Go with real-time voice communication, written completely from scratch.

Features

• 🎙️ Real-time Voice Communication - Crystal clear Opus-encoded audio
• 🔐 Authentication - Admin token-based access control
• 💬 Channel Management - Create, join, and manage voice channels
• 👥 User Presence - Real-time online status tracking
• 🚀 High Performance - Handles 100+ concurrent users
• 🧪 Comprehensive Testing - 57+ test functions with race condition detection

Quick Start

Build

make build

Run Server

./bin/openspeak-server -port 50051 -log-level info

The server will output an admin token that clients can use to connect.

Run Tests

make test

Architecture

Core Components

1. Authentication (internal/auth/)

   • Token generation and validation
   • Permission checking
   • Token revocation

2. Channel Management (internal/channel/)

   • Create/update/delete channels
   • Member management
   • Capacity limits

3. Presence Tracking (internal/presence/)

   • Session management
   • Status tracking (ONLINE, IDLE, OFFLINE)
   • Idle detection
   • Mute state tracking

4. Voice Streaming (internal/voice/)

   • Voice packet routing
   • Channel-based broadcasting
   • Concurrent packet handling

Services (gRPC)

AuthService

• Login(token) - Authenticate with admin token
• ValidateToken(token) - Validate a token
• GetMyPermissions() - Get current user permissions

ChannelService

• CreateChannel(...) - Create new channel
• JoinChannel(id) - Join a channel
• LeaveChannel(id) - Leave a channel
• ListChannels() - List all channels
• ListMembers(id) - List channel members
• SubscribeChannelEvents(id) - Subscribe to channel events

PresenceService

• GetMyPresence() - Get current user presence
• GetUserPresence(id) - Get another user's presence
• ListOnlineUsers() - List all online users
• ListChannelMembers(id) - List members in channel
• SetPresenceStatus(status) - Update status
• SetMuteStatus(...) - Update mute state
• SubscribePresenceEvents() - Subscribe to presence changes

VoiceService

• PublishVoiceStream(stream) - Send voice packets
• SubscribeVoiceStream(id) - Receive voice packets from channel

Testing

The project includes comprehensive tests with:

• 57+ Test Functions covering 100+ scenarios
• Unit Tests for individual components
• Integration Tests for component interaction
• Concurrency Tests with up to 100 concurrent operations
• Race Condition Detection enabled by default
• Edge Case Coverage for error handling

Run tests:

go test ./... -v -race
