mic-mute

🎙️ Free, open-source global mic mute for Windows — one hotkey silences every app, per-device, with a tray indicator. 100 MB portable, MIT.

Features

• ✅ System-wide mute hotkey — Ctrl+Alt+M mutes the default capture device in Discord, Zoom, Teams and OBS at once
• ✅ Push-to-talk mode — hold the hotkey to unmute instead of toggling, for calls where open mic is not allowed
• ✅ Per-device targeting — pick the exact microphone when several are connected; hotkey applies only to it
• ✅ Level meter — live input bars show whether the app is actually hearing you after mute
• ✅ Tray state icon — red slash when muted, green waveform when live; no overlay window in the way
• ✅ No driver, no rerouting — uses Core Audio endpoint control; apps see a normal muted device
• ✅ 100 MB self-contained exe — runtime bundled, no installer, offline, MIT with CI-built SHA-256 releases

FAQ

how to mute microphone with a keyboard shortcut in Windows?

Windows still has no global mic mute switch, so mute lives three clicks deep in Sound settings — mic-mute binds it to one hotkey that works from any app. It controls the real capture endpoint through Core Audio, so every meeting app sees the standard mute state and nothing is spoofed. It is a 100 MB portable exe, offline, MIT, no account and no telemetry.
