ODIN Voice

Cross-platform real-time voice chat SDK for games and applications.

Key Features: 3D spatial audio, noise suppression, echo cancellation, low latency, cross-platform (mobile, web, desktop in same room), data channels for custom game data.

Version Note: ODIN Voice 1.x and 2.x are not interoperable. All participants in a room must use the same major version.

Node.js SDK

Server-side voice chat with native C++ bindings. For recording bots, AI voice assistants, server-side audio processing, and content moderation.

Core SDK (C/C++)

Low-level C API foundation for all ODIN Voice SDKs. For custom platform integrations or language bindings.

ODIN Fleet

Platform Fundamentals

Core concepts, authentication, pricing, and architecture that apply across all ODIN products.

Authentication

ODIN uses a two-level authentication system:

  1. Access Key — API credential for generating tokens (server-side only, never expose to clients)
  2. Room Token — JWT signed with Ed25519, used by clients to join rooms

CRITICAL: Never embed access keys in client code in production. Generate room tokens on a server.

Core Concepts

  • Rooms — Virtual spaces where peers communicate
  • Peers — Participants in a room, each with a unique peer ID
  • Media Streams — Audio channels (microphone input/output)
  • Data Channels — Custom binary/text data between peers
