Quick Start

For Developers

  1. Start with 009-development-guidelines.md for setup
  2. Review 006-server-core.md for architecture
  3. Consult 007-protocol-definition.md for proto definitions
  4. Read feature specs for implementing specific components

For DevOps

  1. Review 008-deployment.md for deployment options
  2. Check 006-server-core.md for configuration
  3. Consult for operational procedures and monitoring

For Understanding Features

  1. 001-audio-streaming.md - How voice works
  2. 002-authentication.md - How access control works
  3. 003-channel-management.md - How channels work
  4. 004-user-presence.md - How presence tracking works
  5. 005-client-application.md - How the UI works

Key Design Decisions

Architecture

  • Client-Server Model: Separate client and server applications
  • gRPC+Protobuf: Efficient binary protocol with streaming support
  • Server Broadcast: Server broadcasts voice packets to channel members (not P2P or SFU)
  • Modular by Feature: Packages organized around domain concepts

Technology

  • Language: Go (server), Go with Fyne (client GUI)
  • Audio: Opus codec for low-latency, high-quality voice
  • Concurrency: Goroutines and channels for scalability
  • Storage: In-memory (MVP), database support (future)

Performance Targets

  • Voice Latency: <100ms end-to-end
  • Audio Bitrate: 64 kbps default (8-128 kbps range)
  • Jitter Buffer: 50ms (configurable 20-100ms)
  • Server Capacity: 100+ concurrent users per server (scalable)

Specification Conventions

Status Levels

  • Planned: Feature specification complete, implementation scheduled
  • In Progress: Implementation started
  • Complete: Implementation done, tested, and deployed

Priority Levels

  • Critical: Must have for MVP, foundation for other features
  • High: Important for initial release
  • Medium: Nice to have for v1.0
  • Low: Future enhancement

Phase Strategy

  • Phase 1 (MVP): Core voice communication with admin tokens
  • Phase 2: User accounts and persistent data
  • Phase 3+: Advanced features (video, screen share, etc)

Updating Specifications

When modifying specifications:

  1. Update the version number and status
  2. Add a changelog entry at the bottom
  3. Maintain backwards compatibility notes
  4. Update related specifications if needed
  5. Verify implementation matches specification
