Hey Product Hunt community! 👋 I'm Kishor, the maker behind **MicShield**. I built MicShield after having one too many near-heart-attacks on video calls. We've all had that moment: you think you're safely muted, only to discover a browser tab unmuted in the background, or an app shortcut didn't register. Software mutes inside individual apps fail all the time. I wanted a solution that was **physical, undeniable, and impossible to bypass**. ### 🛡️ How MicShield solves it: 1. **Hardware-Level Muting**: Instead of asking Zoom or Chrome to mute, MicShield cuts audio input directly at the macOS CoreAudio driver level. Even if an app tries to listen or unmute, the microphone hardware stream sends pure silence. 2. **MacBook Notch HUD**: When muted, an ambient red halo frames your physical camera notch so you can see your status in your peripheral vision without glancing at the menu bar. (It smoothly transforms into a floating Dynamic Island pill on external monitors). 3. **Smart Safety Net**: It auto-mutes when your Mac sleeps, locks, or if your AirPods/Bluetooth headphones disconnect. 4. **Push-to-Talk**: Hold shortcut to speak like a walkie-talkie, or use Push-to-Mute for coughs. 5. **100% Privacy & No Subscriptions**: Native Swift/AppKit, Apple-Notarized, runs 100% locally with zero telemetry and zero audio recording. You can try the full 7-day trial via Homebrew: ```bash brew install kishorgaikwad2016/tap/micshield Or download the direct DMG from our GitHub page. I'll be hanging out in the comments all day — I'd love to hear your feedback, thoughts on the notch animation, and what features you’d like to see next! 🚀

Hey Product Hunt! 👋 I'm Kishor, the creator of MicShield.

Like many of you, I spend hours every day jumping between Zoom, Google Meet, Teams, and Slack calls. And like many of you, I've had that recurring moment of anxiety: "Wait... is my mic actually muted right now?"

Most apps only mute inside their own window, which fails if a background browser tab or secondary tool is capturing audio. I wanted something physical, unambiguous, and bulletproof:

1. Physical Notch HUD: Apple introduced the camera notch, so why not make it useful? MicShield frames your physical camera cutout with a gentle red ambient glow when muted, and pulses a waveform when unmuted. You never have to hunt for window tabs. (It also turns into an elegant floating pill on external monitors!)

2. CoreAudio Hardware Silence: Instead of software-level mutes that apps can bypass, MicShield commands macOS CoreAudio directly to double-lock input gain to 0.0. Zero audio data passes through.

3. Smart Safety Net: It senses when your AirPods disconnect, when your Mac sleeps or locks, or when a meeting ends, and automatically cuts the mic.

4. 100% Private & Native: Built in native Swift, notarized by Apple, zero analytics, zero external network requests.

You can install it in 5 seconds via Homebrew:

brew install kishorgaikwad2016/tap/micshield

Or download the notarized DMG directly on GitHub: https://github.com/kishorgaikwad2016/MicShield

It comes with a 7-day free trial and a lifetime license (no subscriptions).

I'd love to hear your feedback, thoughts on the notch HUD, and any features you'd like to see next!
