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.
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.
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.
The native audio engine reads the selected physical microphone in real time.
Echo cancellation runs independently, followed by neural background-noise suppression.
Zoom, Meet, Teams, Discord, and other apps receive the cleaned microphone signal.
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.
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.
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 on Linux the microphone is created by PipeWire or PulseAudio with nothing to install.
Test the effect with your own microphone before installing the desktop app.
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.
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.
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.
No. Kleervox processes microphone audio locally on the computer. The audio is not uploaded for noise or echo cancellation.
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.
Add traffic, café chatter, keyboard-like transients, or other sample noise in the browser demo, then switch between the original and cleaned signal.
