ProxVC++
by IsLocal
ProxVC++ adds proximity voice chat to BTA Babric servers, so players hear nearby players and not distant ones.
What it does
Proximity voice chat for BTA Babric servers, with a simple set of quality-of-life features. Players can set a per-player volume mixer, and sound occlusion reduces audio passing through blocks. A movable and toggleable HUD lets players place or hide the voice display, and voice waveforms are drawn clearly.
Voice traffic travels over UDP, on the same address and port as the Minecraft TCP server, so the server has to allow UDP through its firewall. A mic indicator in the bottom left shows the current audio input state, including when the microphone is muted, and the mod handles a missing input device without failing. Installation needs HalpLibe and Mod Menu (BTA Port), and both the server and every client need ProxVC++ installed with the microphone configured.
The mod is published for 1.7.2 on BTA Babric, with 1.6.1 as the latest file on the beta channel, dated 2026-04-27. It is released under the MIT License, and its source code and issue tracker are public.
Key features
Proximity voice
Voice reaches players based on their distance in the world, so nearby players hear each other while distant ones do not.
Per-player volume mixer
Each player's voice volume can be adjusted separately, so a loud talker can be turned down without affecting others.
Sound occlusion
Audio passing through blocks is muffled, so walls and terrain between players change how their voices sound.
Movable and toggleable HUD
The voice HUD can be moved on screen or hidden, and waveforms are drawn for clearer voice feedback.
Microphone indicator
A mic indicator in the bottom left reflects the current input state, including muted and missing input devices.

Use cases
Small survival servers
Groups playing on a BTA Babric server can talk while building and exploring, with voices fading as players move apart.
Who it’s for: Server owners running BTA Babric 1.7.2 who want proximity voice, and players on those servers who want a volume mixer and a movable voice HUD. Both sides need the mod, and a firewall that allows UDP traffic on the server's port.

What the author says
Simply install the mod on both the server and the client, configure your mic input, and voilà! The mic indicator found at the bottom left should reflect the current state of your audio input including if you are muted, talking, idle, or missing an input device.
