Noise cancellation for Windows
Windows 10 and 11, with a one-time guided driver step.
Clearer microphone audio
AI noise cancellation for clearer calls
Kleervox removes background noise and speaker echo before your mic reaches Zoom, Google Meet, Microsoft Teams or Discord. Processing stays on your computer.
What it removes
Keep the room out of the meeting
A speech-trained model removes steady hum and sudden noises while keeping your voice clear.
- Keyboard clicks
- Fans and air conditioning
- Traffic and construction
- Café chatter
- Barking dogs
- Speaker echo
How it works
One clean microphone for every call app
Pick the Kleervox virtual microphone once in your call app. It then works like any normal mic.

Clean noise and echo
Echo cancellation, then neural background-noise suppression.
- 3
Send a virtual microphone
Zoom, Meet, Teams, Discord and other apps get the clean signal.

Noise cancellation and echo cancellation solve different problems
A fan is noise. The other person’s voice coming back through your speakers is echo — and because it is speech, a noise filter alone won’t remove it.
On-device processing keeps live audio private
Noise and echo cancellation run on your computer. Your microphone audio is never sent to a cloud service or a meeting bot.
Works across call apps
The same noise-cancelled mic in Zoom, Meet, Teams, and Discord
Every app, one setting
Zoom, Google Meet, Microsoft Teams, Discord, Slack, OBS and browser calls. Built-in suppression only covers one meeting product; a system-level virtual microphone covers them all.
Choose “Kleervox Microphone”
Select it as the input in your call app. Your real microphone, the cleaning strength and echo cancellation stay in Kleervox.
Headphones still win on echo
Echo cancellation helps when you must use speakers. Room shape, speaker distortion and microphone placement affect how much it can remove.
Frequently asked
AI noise cancellation questions
What is AI noise cancellation?
AI noise cancellation uses a speech-trained model to distinguish a person’s voice from unwanted sound. During a live call, it reduces background noise before the microphone signal reaches the meeting app.
Does Kleervox work with Zoom, Google Meet, and Microsoft Teams?
Kleervox creates a virtual microphone that can be selected in Zoom, Google Meet, Microsoft Teams, Discord, Slack, OBS, and other apps that let you choose an audio input.
What is the difference between noise cancellation and echo cancellation?
Noise cancellation targets sounds such as keyboards, fans, traffic, and chatter. Echo cancellation targets the far-end voice that plays through your speakers and leaks back into your microphone. Kleervox treats them as separate stages.
Is microphone audio uploaded for processing?
No. Kleervox processes microphone audio locally on the computer. The audio is not uploaded for noise or echo cancellation.
Can I test the noise cancellation before downloading?
Yes. The browser demo lets you combine your microphone with sample background sounds and compare the original and cleaned result. The desktop app is required to clean audio inside live call apps.
