QuietMic strips out background chatter, keyboard clacks and street noise from your microphone in real time — before it ever reaches your meeting.
Why QuietMic
Two neural noise-suppression engines, tuned for real conversations in noisy places — not just steady hiss.
Switch live between RNNoise (ultra-low latency) and DeepFilterNet — a modern deep model that erases café chatter and clatter.
Most tools only kill constant noise. DeepFilterNet handles the hard stuff: overlapping voices, cutlery, espresso machines, traffic.
All processing happens on your PC. Your audio never touches the internet — no account, no cloud, no telemetry, ever.
Route the clean signal into a virtual mic and pick it in Zoom, Teams, Meet, Discord, OBS — anything that uses a microphone.
Runs quietly in the system tray. A global hotkey (Ctrl+Alt+Q) toggles it from anywhere — even mid-call, window hidden.
One self-contained app, no runtime to install, no restart. Starts cleaning your mic in seconds.
How it works
Run the installer (or unzip the portable build) and open QuietMic. It finds your mic automatically.
For meetings, install the free virtual cable and set QuietMic’s output to it. To just A/B test, send it to your headphones.
In your meeting app, choose the virtual mic. That’s it — everyone hears you, not the café.
Download
Download, install, and start cleaning your mic in under a minute.
Questions
Yes — with any app that uses a microphone. QuietMic outputs the cleaned audio to a virtual microphone that you select inside your meeting app. A free virtual-cable driver (VB-Audio Cable) handles the routing; setup takes a minute.
No. Everything runs locally on your PC. QuietMic has no network access, no account, and no telemetry. Your voice never leaves your machine.
RNNoise is extremely light and low-latency, great for steady noise (fans, hiss, street). DeepFilterNet is a modern deep-learning model that’s dramatically better at non-stationary noise like overlapping café chatter — at a slightly higher latency. Switch between them anytime.
No. It uses a small fraction of one CPU core on any modern laptop and needs no GPU. The whole app is a single ~33 MB executable.
Until the app is code-signed you may see a one-time SmartScreen “Windows protected your PC” prompt — click More info → Run anyway. It’s safe; the warning simply appears for new indie apps.
Yes — QuietMic is free to download and use. No account, no trial timer, no watermark. Just download it and go.
