MicLocker: Stop Mic Switching
Keeps Your Default Audio Input
Only for Mac
$1.99
Mac
Someone said you sound like a tin can? MicLocker holds your default audio input and puts your chosen microphone straight back when a headset or earbuds connect.
"You sound like a tin can."
Someone says it twenty minutes into the call. That is how you find out your good microphone stopped being the one your Mac was using. It was sitting right there the whole time.
MicLocker ends that. You pick your microphone once. It stays picked.
Why does my Mac keep switching my microphone?
Because your Mac decides for you every time a new piece of audio gear shows up. AirPods connect. A wireless headset pairs as you sit down. A USB mic or an audio interface wakes up after sleep. You dock the laptop, or plug in a monitor, and your voice quietly moves to whatever arrived last.
You fix it in your sound settings. Then it happens again tomorrow. And the day after that.
MicLocker keeps your default audio input where you put it. When something else takes your microphone, your choice goes straight back, in an instant, with nothing for you to click.
When does my microphone get switched?
• In the middle of a job interview, when the other person tilts their head and asks you to say that again.
• Halfway through a podcast take you cannot redo, when a pair of earbuds connects and your studio mic goes quiet.
• At the standup, where you talk for ninety seconds and nobody hears a word of it.
• On the client call you joined right after docking, sounding like you are in a stairwell.
• On the guitar part you are tracking, when your audio interface comes back on and your take goes in through the wrong microphone.
Same answer every time: your microphone, back in place, quietly.
How do I stop my microphone from changing?
• Click the MicLocker icon in your menu bar.
• Pick the microphone you want to keep.
• Forget about it. That is the whole setup.
No tinkering. No maintenance. No checking your sound settings before every call, ever again.
The calm is the part you notice. No scrambling through settings while people wait. You just talk, and you sound the way you are supposed to sound.
What happens if I unplug my locked microphone?
Nothing is lost. MicLocker holds on to your choice and shows that mic as not connected, so you are never left guessing. Plug it back in and your microphone comes back on its own. It never forgets what you picked, no matter how many days it sits in a bag.
What does the menu bar icon mean?
One glance and you know where you stand.
• Filled microphone: your mic is held and connected.
• Crossed-out microphone: your mic is not connected right now.
• Outline microphone: the lock is off.
Can I turn it off when I want to?
Any time. Open the menu, choose not to hold any microphone, and your Mac goes back to doing its own thing. Quit from the same menu whenever you like. You can also have MicLocker start when you log in, so your mic is protected before your first call.
Does MicLocker need microphone permission?
No. It never listens to you, so it never asks. No permission prompt, ever.
Is MicLocker private?
• No microphone access. Not once.
• No internet connection, so nothing leaves your Mac.
• No tracking, no analytics, no data collected.
• No account, no sign-up, no email address.
What does MicLocker not do?
It will not mute you or unmute you. It will not record, change or reroute your sound. It will not touch your speakers, your headphones or anything you hear. It makes one decision and one only: which microphone your Mac uses. Everything else stays exactly as you left it.
Who is MicLocker for?
• People living in back-to-back video calls, online meetings and team standups.
• Podcasters, streamers and musicians guarding a USB mic or an audio interface.
• Remote workers who want to sound the same on every single call.
• Anyone pairing wireless earbuds with a better microphone on the same Mac.
MicLocker sits quietly in your menu bar, stays out of your Dock, and works on any Mac.
Pick your microphone once. Stop apologizing for your audio. Download MicLocker and stop thinking about your microphone for good.
