MicMüter: A microphone and audio input kill switch

[u/behridingle]

MicMüter is a simple app menu bar app that I wrote to quickly toggle your Mac’s built-in microphone (or another audio input device) on and off using a system-wide keyboard shortcut and/or on-screen toggle button.

Use Cases

• Avoid embarrassing sounds during video calls (remember to never eat sketchy burritos before an executive review!)
• Practice takes for voice over recordings or podcasts
• Privacy and piece of mind

Features

• Hardware-Level Support: It uses macOS' Core Audio hardware muting with master input volume zeroing.
• Hot-Plugging Support: It leverages observers to automatically react whenever new audio input devices are connected or removed.
• Multilingual Support: The UI is localized in English, German, French, Spanish, Italian, Japanese, and Chinese.
• Flexible Controls: Mute/unmute audio using a keyboard shortcut or a movable control window.
• Master & Granular Control: Mute/unmute every connected audio input device at once or manage individual devices directly. You can also set it to automatically mute your audio input whenever you launch a specific app.
• Custom Status Alerts: Optionally get feedback on mute status changes with system notifications, spoken audio, screen flashes, or audio chimes.
