Public beta

Beta testing

NSSVC is still being tested. Reports from different hardware, regions, and Minecraft servers are useful.

Before testing

  • Install Fabric Loader, Fabric API, and the current NSSVC beta JAR on every participating client.
  • Read the in-game privacy notice before enabling voice.
  • The default controls are N for settings, V for push-to-talk, and M for mute or deafen. All can be rebound in Minecraft Controls.
  • Use the Players tab for individual volume and block controls.

Your first 10 minutes

  1. Open airStand nearby and confirm speech is clear while facing each other.
  2. DirectionTurn your back while speaking and listen for the source directivity change.
  3. WallMove behind a solid wall and compare the muffling with an open doorway.
  4. WaterSpeak above, across, and below the water surface.
  5. TravelChange lobby or dimension and confirm voice reconnects without help.

What is most useful to test

  • Conversation while walking between open areas, walls, doors, and water.
  • Lobby, dimension, proxy, and server changes without manually reconnecting.
  • Different microphones, headphones, speakers, operating systems, and RNNoise support.
  • Long-distance users and unstable Wi-Fi, especially when only one direction sounds choppy.
  • Busy lobbies with several nearby simultaneous speakers.

Current limitations

  • Voice uses encrypted WSS transport but is not end-to-end encrypted.
  • The beta currently uses one dedicated six-worker relay location, so distant regions need more latency testing.
  • Windows x64 has the widest RNNoise device coverage; Linux, macOS, and ARM need more testing.
  • Essential shared worlds are supported but need wider testing across Essential releases.
  • NSSVC is not approved by Hypixel, Mojang, Microsoft, or any Minecraft server.

Bug reports

Include the NSSVC version, operating system, audio devices, transmission mode, approximate region and latency, what happened, and whether the speaking icon remained lit. Include the Minecraft log for crashes. Never post Minecraft access tokens or other private credentials.
