Three-minute setup
Hear it with one friend.
No Minecraft server setup. Both players install the mod, meet in the same lobby, and talk.
Meet in one lobby
Open NSSVC with N. The Status tab confirms when another NSSVC user is nearby.
Hold V and move
Walk around a wall, turn away, then enter water. The sound should change with the world.
How it works
The server stays untouched.
NSSVC sends voice through a separate authenticated relay. Only players with the mod can use or hear voice.
Use it on existing servers
Public servers, private servers, singleplayer, and supported Essential worlds require no server changes.
Spatial audio
Distance, direction, walls, and water affect how nearby players sound.
Speech, not silence
Push-to-talk or voice activity, noise suppression, and Opus keep unnecessary traffic down.
