Kleervox
Clearer microphone audio

AI noise cancellation for clearer calls

Kleervox removes background noise and reduces speaker echo before your microphone reaches Zoom, Google Meet, Microsoft Teams, Discord, or another call app. Processing stays on your computer.

What it removes

Background sounds should not become part of the meeting

Traditional filters are useful for steady hum, but real rooms contain changing sounds. A speech-focused neural model can reduce both continuous and intermittent noise while keeping the voice at the centre of the signal.

  • Mechanical keyboard clicks
  • Computer fans and air conditioners
  • Traffic and construction
  • Café chatter and household activity
  • Barking dogs and other intermittent sounds
  • Speaker echo returning through the microphone
How it works

One clean microphone for every call app

The desktop app sits between the physical microphone and the meeting software. You choose the Kleervox virtual microphone once in the call app; the cleaned signal then follows the same path as any normal microphone.

  1. 01

    Capture your microphone

    The native audio engine reads the selected physical microphone in real time.

  2. 02

    Clean noise and echo

    Echo cancellation runs independently, followed by neural background-noise suppression.

  3. 03

    Send a virtual microphone

    Zoom, Meet, Teams, Discord, and other apps receive the cleaned microphone signal.

The processing is the same everywhere; how the clean microphone reaches your call app depends on the operating system.

Noise cancellation and echo cancellation solve different problems

A fan or keyboard is background noise. A remote participant’s voice playing through your speakers and returning through your mic is acoustic echo. Removing only background noise does not reliably remove that echoed voice, because it is still speech.

Kleervox keeps the controls independent: noise cancellation can be turned off to save processing while echo cancellation remains available where the platform supports it.

On-device processing keeps live audio private

Noise and echo cancellation run locally. Your microphone audio does not need to be sent to a cloud service, stored for later processing, or exposed to a meeting bot.

This also means the cleaning path can keep working when the internet connection is unstable; only the call app itself needs the network.

Works across call apps

Use the same noise-cancelled mic in Zoom, Meet, Teams, and Discord

Built-in suppression is tied to one meeting product. A system-level virtual microphone is useful when the day moves between Zoom, Google Meet, Microsoft Teams, Discord, Slack, browser calls, recording tools, and streaming software.

After installing Kleervox, open the audio settings in the call app and choose “Kleervox Microphone” as the input. Your real microphone remains selected inside Kleervox, where the cleaning strength and echo cancellation can be controlled.

Headphones remain the most reliable way to eliminate acoustic speaker echo completely. Echo cancellation is designed for situations where speakers must be used, but room shape, speaker distortion, and microphone placement affect the result.

Setup differs by platform: noise cancellation for Windows includes a one-time guided driver step, while noise cancellation for Linux creates the microphone with PipeWire or PulseAudio and nothing to install.

Frequently asked

AI noise cancellation questions

Test the effect with your own microphone before installing the desktop app.

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.
