From Zero to Voice Chat in 5 Minutes
Real working code. Pick your platform and start building.
Spatial Voice in Unity
3D positional voice chat — voices come from player positions.
using OdinNative.Unity;
using UnityEngine;
public class VoiceChat : MonoBehaviour
{
void Start()
{
OdinHandler.Instance.OnMediaAdded.AddListener(OnMediaAdded);
OdinHandler.Instance.JoinRoom("MyGame");
}
void OnMediaAdded(object sender, MediaAddedEventArgs args)
{
var room = sender as Room;
if (room?.Self?.Id == args.PeerId) return;
// Attach voice to the player's GameObject
var player = FindPlayerByPeerId(args.PeerId);
var playback = OdinHandler.Instance.AddPlaybackComponent(
player, room.Config.Name, args.PeerId, args.Media.Id);
// Enable 3D spatial audio — voices come from player positions
playback.PlaybackSource.spatialBlend = 1.0f;
playback.PlaybackSource.maxDistance = 30f;
}
}
Voice Chat for Web
Full voice chat room in one async function.
import * as ODIN from "@4players/odin";
import * as Plugin from "@4players/odin-plugin-web";
// Initialize audio plugin (once per app)
const plugin = Plugin.createPlugin(async (sampleRate) => {
const ctx = new AudioContext({ sampleRate });
await ctx.resume();
return ctx;
});
ODIN.init(plugin);
// Join a voice chat room — that's it
async function joinVoiceChat(token: string) {
const room = new ODIN.Room();
room.onPeerJoined = ({ peer }) =>
console.log(`${peer.userId} joined the room`);
room.onPeerLeft = ({ peer }) =>
console.log(`${peer.userId} left the room`);
await plugin.setOutputDevice({});
await room.join(token, {
gateway: "https://gateway.odin.4players.io",
});
// Start sending microphone audio
const mic = await ODIN.DeviceManager.createAudioInput();
await room.addAudioInput(mic);
}
One Platform vs. Multi-Vendor Chaos
The Multi-Vendor Mess
Vivox for voice, PlayFab for hosting, Hive for moderation — three vendors, three dashboards, three billings.
- 3 vendors, 3 dashboards, 3 billings
- No native integration between services
- Voice moderation requires custom pipeline
- Hidden egress + per-minute fees
- Self-hosting? Build it yourself
The Integrated Stack
Voice + Fleet + Cortex + Rooms from a single provider. Everything works together.
- One account, one dashboard, one invoice
- Data flows natively between all layers
- Cortex analyzes audio streams directly
- Flat, predictable pricing from €0/month
- Self-host the entire platform on your infra
