robloxmic

Censors your microphone before Roblox hears it, using Roblox’s voice-safety classifier. Flagged speech is replaced with a beep.

Requirements

• Windows 10/11
• Python 3.11–3.14
• VB-Cable

Running

Double-click start.bat. Or:

pip install -r requirements.txt
python main.py

In Roblox: Esc → Settings → Input Device → CABLE Output.

Options

Add --console to run without the window, and --save to keep options for next time.

• --provider dml: run on the GPU
• --censor silence: silence instead of a beep
• --threshold 0.35: catch more (default 0.5)
• --pad-before 0.1 --pad-after 0.1: censor more either side, in seconds
• --window 1.0: also catch whole-sentence requests, like asking for personal info
• --simulate in.wav out.wav: filter a recording

python main.py --help lists the rest.

macOS

Untested. Install BlackHole, run python3 main.py, and pick BlackHole 2ch as the Input Device in Roblox. PRs welcome.
