SocketSVC Mod (26.3, 1.21.11) – Talk to Nearby Players Without Opening

SocketSVC Mod brings real-time 3D proximity voice chat to Minecraft. It sends voice over WebSockets instead of UDP, so you do not need a second port on your firewall. Players hear each other based on how close they are in the game. Voice uses the same kind of connection your browser uses for HTTPS. You can also use it in singleplayer by opening your world to LAN.

Features:

• Proximity Voice: Players hear each other based on distance, with volume falloff and left and right panning.
• WebSocket Connection: Voice starts as a normal HTTP upgrade, so there is no extra port to forward.
• Voice Groups: Join named channels from the in-game menu.
• Soundboard: Play local clips to nearby players.
• Noise Cleanup: Cuts background noise with RNNoise. DeepFilterNet is an optional download.
• Instruments: Play with a MIDI keyboard, line-in, drum machine and loop station.
• Works behind a reverse proxy, Cloudflare Tunnel, ngrok, or a Docker or Pterodactyl panel with no extra setup.
• Uses real wss:// encryption from the TLS setup you already run.
• Sends audio, the player list, speaker info and status updates through one single socket.
• Lets a proxy relay put a whole network behind one public port, so backend voice ports stay private.
• Gives you push-to-talk or voice activation, plus mute and deafen.
• Lets you change the volume of each player, so you can turn one person down without muting everyone.
• Uses Opus audio with a jitter buffer, packet-loss concealment and automatic reconnect.
• Adds echo cancellation, automatic gain and limiting for cleaner sound.
• Adds headphone spatial audio, head animation that follows the speaker’s voice, and custom icon packs, including animated ones.

Commands:

• /ssvc-server reload: reloads the server settings after you change them.

Configuration:

• public-url: the address your players use to reach the voice server.

How to Use:

1. Put the client mod on every player’s game, and one server piece on the server.
2. Start the server once. It creates config.yml on Paper or socketsvc-server.yml on the server mod.
3. Set public-url to an address your players can reach, then run /ssvc-server reload.
4. Press V in game to open settings.
5. Press B to talk.
6. Press G to open voice groups.
