StillmicWorks in every app.
Zoom, Meet, Slack, Discord, your browser. If an app lets you choose a microphone, Stillmic works there.
Noise removal for your Mac’s mic
Just your voice.
Stillmic takes the fan, the keyboard and the street
out of your microphone, in every app, right on your Mac.

The real Stillmic engine, flipped live. An AI voice with fan and keyboard noise added, at matched levels. Use headphones if you can.
How light it is
Light enough to forget about.
- of one CPU core, on a real call
- ~7%
- of memory, estimated, while you talk
- ~16 MB
- CPU measured when no app is using the mic
- 0.0%

Early measurements on an M4 Pro. Yours will vary with your Mac and how much you talk. macOS’s own audio service uses some CPU on top.
How it works
Pick it like any other mic.
Stillmic adds a microphone to your Mac. Choose it in your call app and everyone hears the clean version.
Stays on your Mac.
Your voice is cleaned on your Mac and never stored or sent anywhere. No account and no analytics.
Idle means idle.
The noise engine only runs while an app is using the Stillmic mic. The rest of the day it’s asleep and your real mic stays closed.
Two strengths.
Standard keeps your voice smooth. Aggressive cuts harder between words. Switch from the menu bar at any time.
Questions.
Does it clean up other people on the call?
No. Stillmic only cleans your microphone.
Why does it ask for my password?
Once, to install the virtual microphone, which macOS keeps in a system folder. All audio on your Mac stops for a moment while it loads.
What happens if I quit the app?
The Stillmic mic goes silent, so it never plays old audio. Pick your normal mic to stop using it, or leave Start at Login on.
Can I use Bluetooth earbuds as the mic?
You can, but Bluetooth mics usually drop your earbuds into lower-quality call audio. A built-in or USB mic generally sounds better.
What’s it built on?
DeepFilterNet3, an open-source speech model, hand-ported to C so it runs with no machine learning framework. The code is on GitHub under the MIT license.
