Remove background noise from audio and video — free AI noise reduction

Clean hum, fan noise, keyboard clicks and other background noise from lectures, meetings, interviews and videos with AI. Compare before and after instantly; for videos, the picture stays untouched and only the sound is replaced.

We're not interested in your data. A platform built free from surveillance.

Drop a recording or video with background noise

Choose file

MP3 · WAV · M4A · MP4 · MOV · WebM

The AI runs on your device — your recording is never uploaded. Works best on speech: lectures, meetings, interviews, voice-overs.

Keeps the voice, removes the noise

An open-source AI trained to tell speech from noise (RNNoise) processes the sound in tiny slices. Choose Strong, Natural or Light and listen.

Play the original and the cleaned version side by side.

Videos too

For video files the picture isn't re-encoded — only the audio is swapped for the clean version and saved as MP4. You can also download just the audio as MP3 or WAV.

Instead of a paid service

Similar tools usually cost money or require uploading. Here the AI runs on your computer, so it's free and your recording stays private.

Frequently asked questions

Does it work on music?

It's tuned for speech, so music can be reduced too. For songs, use Light or skip it.

Can it handle long recordings?

Yes. An hour of audio takes from tens of seconds to a few minutes depending on your computer.

Is my recording uploaded?

No. Everything happens in your browser.
