A Chrome extension that automatically mutes your microphone on Google Meet when you're not speaking, preventing background noise from reaching other participants.
Features
Auto-unmutes when speech is detected, auto-mutes after you stop speaking
4 operating modes:
Off — Extension disabled, Meet default behavior
Auto — Speech-triggered unmute & auto-mute (for quiet environments)
Auto-Off — Unmute only by Meet manual control or shortcut, auto-mute after speech (for noisy environments)
Push-to-Talk — Hold shortcut key to speak
Popup mic button — mute/unmute directly from the popup without closing it. In Push-to-Talk mode, the button works as hold-to-talk (press and hold to unmute, release to mute)
Customizable shortcut key (default: Ctrl+Shift+M) — available in all modes except Off
Independent audio monitoring (separate mic stream from Google Meet)
Voice-weighted noise gate — emphasizes human voice frequencies (300Hz–3kHz), reducing false triggers from keyboard, fan, and ambient noise
Asymmetric threshold design prevents chattering
Real-time audio level meter & spectrum analyzer
Per-mode sensitivity and grace period (each mode remembers its own settings)
Manual mute safety — if you click Meet's mute button directly, the extension automatically switches to Off mode to avoid interference
Microphone device selector — choose which mic to use
4 visual themes (Default / Analog Radio / Boombox / Retro Future)
Mode-aware toolbar icon — icon color and badge change based on active mode
English & Japanese language support with manual switching
Bored in a meeting? Retro-future mini-games included (Breakout / Space Invaders / 2048 / Flappy Bird). Fair warning: game sound effects can trigger auto-unmute. Set your sensitivity just right and enjoy the thrill of not getting caught.
A separate microphone stream monitors audio levels. When speech is detected, the extension automatically clicks the Meet mute button to unmute. When silence returns, it re-mutes after a configurable grace period.

Manual Mute Safety
When you manually mute or unmute via the Meet mute button, the extension automatically switches to Off mode. This prevents the extension from unexpectedly turning your mic back on after you intentionally muted it.

Manual mute button click → extension switches to Off mode
Use the shortcut key (Ctrl+Shift+M) to control mute while keeping the extension active
