An unofficial client for the Simple Voice Chat protocol. On a server with the Simple Voice Chat mod or plugin, you can talk with players who use the Java mod on the regular launcher.

What it does

Menu (V): connection status, microphone and voice chat on/off, push to talk or voice activation, voice volume, microphone gain and activation level with a live meter, and every hotkey as it is bound now. The right side lists the server's groups with their members: join (with a password if needed), leave, or create a group.
Talking: hold Caps Lock (push to talk) or use voice activation. Voices come from where players stand, getting quieter with distance and panned left or right.
Groups: each player's group shows above their head. /vc join <group> [password], /vc leave, /vc create <name> [password] [normal|open|isolated] and /vc groups work too.
Keys (Options > Mods > Horizon Voice Chat): menu (V), push to talk (Caps Lock), whisper (unbound), mute (J), voice chat off/on (K).
Protocols: Simple Voice Chat 2.6.x (compatibility 20) and 2.7 (21).

What it touches

It reads the server's voicechat:* custom payloads and other players' positions inside game::remote, so it is pinned to Horizon c9d474d.
It opens one UDP connection to the server's voice chat port, encrypted with AES-128-GCM using the secret the server sends.
It uses the default microphone and speakers through cpal, and loads the system libopus at run time (the opus package must be installed).
It keeps its settings in Horizon's own mod settings. It contacts no host other than the Minecraft server you are on (and DNS, for the server's SRV record).

Not affiliated

This project is not made, endorsed or supported by Max Henkel or the Simple Voice Chat project. It contains none of Simple Voice Chat's code: everything is written from scratch in Rust.

The engine's unit tests pass, and the modded client type-checks. Live, against Paper 26.3 with the Simple Voice Chat 2.6.27 plugin, it authenticated and connected, a test tone was heard through the server, and groups and labels came from the server. Not tested yet: the menu in the real game, a real microphone, 2.7 servers, and talking with the Java mod itself.

Native code

A native mod is Rust code that the launcher compiles into a game of its own, the Native mods instance. It is not sandboxed: it can do anything you can on this computer. The launcher builds it only after a warning that names it, and a reviewer read its source before it was listed. Read the source yourself before you build it. How native mods work
