Hush Meet

Hush Meet automatically mutes your microphone on Google Meet when you're not speaking, preventing background noise from reaching other participants.

■ Key Features

• Auto Mute Control
Automatically unmutes when you start speaking and re-mutes after you stop. Asymmetric threshold design prevents chattering (rapid toggling).

• Voice-Weighted Noise Gate
Emphasizes human voice frequencies (300Hz–3kHz), reducing false triggers from keyboard, fan, and ambient noise.

• 4 Operating Modes
Off: Extension disabled — Meet default behavior
Auto: Speech-triggered unmute & auto-mute (for quiet environments)
Auto-Off: Manual unmute or shortcut only, auto-mute after speech (for noisy environments)
Push-to-Talk: Hold shortcut key to speak, auto-mutes when released

• Customizable Shortcut Key (default: Ctrl+Shift+M)
Toggle mute in Auto/Auto-Off modes, hold-to-talk in Push-to-Talk mode. Works in all modes except Off.

• Manual Mute Detection
When you mute or unmute via the Meet mute button, the extension follows your action without changing the selected mode.

• Microphone Device Selector
Choose which microphone to use. Supports any audio input device, not just the system default.

• Real-time Audio Visualization
Audio level meter and 16-band spectrum analyzer visualize your mic input in real time.

• Mode-Aware Toolbar Icon
Icon color and badge change based on the active mode, so you can see the current state at a glance.

• 4 Themes
Choose from Default, Analog Radio (wood grain), Boombox (metallic), and Retro Future (neon synthwave) visual themes.

• Multilingual (7 Languages)
Switch between English, Japanese, German, Chinese, Korean, Spanish, and French manually, or use "Auto" mode to follow your browser language.

• Games
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.
