Did you just purchase ODIN and arrive here? Please generate an Access Key, if you haven't already done so.

Easy integration

ODIN can be easily integrated into all your apps, websites, games, and experiences with a couple of lines of code. As 4Players handles servers and maintenance for you, you'll have a production-ready voice chat and data synchronization layer implemented in your app in no time.

These examples give you an idea of how easy it is to implement ODIN in various programming languages. Please note that these are simplified examples; in real-world implementations, you'll have a few more lines for error handling.

Unity SDK

Our ODIN SDK is deeply integrated into Unity and features automatic 3D spatial audio. Use the tools you know like AudioSource and AudioListener or the built-in Unity AudioMixer for your voice chat integration. Manage all aspects of our Voice SDK within Unity and integrate it in a couple of hours into your game or XR experience.

Add ODIN to your C or C++ projects with our simple to use ODIN Core SDK. Our Core SDK is the foundation of all other SDKs and features an easy-to-use interface.

// Generate access token - should be done on a server
char room_token[512];
OdinTokenGenerator* generator = odin_token_generator_create("__YOUR_ACCESS_KEY__");
odin_token_generator_create_token(generator, "My Room", "John Doe", room_token, sizeof(room_token));
odin_token_generator_destroy(generator);

// Setup event handler and join a room.
OdinRoomHandle room = odin_room_create();
odin_room_set_event_callback(room, handle_odin_event, NULL);
odin_room_join(room, gateway_url, room_token);

Integrating our Voice SDK in any website with vanilla JavaScript is seamless, effortless, and easy. Add our script and join a room, that's it.

<html>
    <head>
        <script type="text/javascript" src="https://4npcdn.com/2355/odin/javascript/latest/odin.min.js"></script>
        <script type="text/javascript">
            var connectOdin = async function(room, user) {
                const token = await getToken(room, user);
                const odinRoom = await ODIN.OdinClient.initRoom(token);
                await odinRoom.join();
                return odinRoom;
            }
            connectOdin("My Room", "John Doe").then(odinRoom => {
               console.log("Connected to room", odinRoom);
            });
        </script>

Adding our Voice SDK to any modern JavaScript framework like Angular, Svelve, Vue, React is super easy. Just add our npm package @4players/odin to your package.json and connect a room. That's it.

import { OdinClient } from '@4players/odin';
import { TokenGenerator } from "@4players/odin-tokens";

const generator = new TokenGenerator(apiKey);
const token = generator.createToken("My Room", "John Doe");
const odinRoom = await OdinClient.initRoom(token);
await odinRoom.join();

Why 4Players?

4Players has been hosting game and voice servers globally for decades. We know what developers need. We know what gamers want. We know how essential reliability, awesome voice quality, low CPU usage, zero FPS hit, noise suppression, and low latency are for a great voice chat experience, especially in immersive real-time applications like games.

VoIP veterans, server admins, gamers, and mod makers came together to create the essential in-game voice chat solution for Unity and Unreal Engine built on the latest software technologies like QUIC and HTTP3. You don't have to worry about maintenance, server hosting, or day-to-day operations. You don't have to learn anything new. You just leverage your Unity skills and focus on delivering the best game possible.

With support for spatial 3D audio as well as massive scalability, zero configuration, or bookkeeping, it has never been easier to utilize best-in-class voice chat for your games, video conferencing, and XR applications.

In addition, we also provide SDKs for various other platforms including the web with TypeScript and Vanilla JavaScript support and even console clients for automatic data processing. With ODIN, all your real-time data synchronization is solved and implemented in no time, whether it's pure data or voice.
