About Remove Background Noise from Audio & Video
Remove background noise from a voice recording, an online class, a vlog or a meeting video right in your browser. An AI noise suppression model separates speech from everything around it, so the air conditioner, the fan, the wind, the street and the people talking in the next room fade away while the voice stays clear. For a video, only the sound is replaced: the picture is copied untouched. Nothing is uploaded and there is no watermark.

- Listen. The first 15 seconds are cleaned straight away. Press play and switch between Original and Cleaned to compare the same moment. To check another part, play the file to it and click Preview from here.

Presets
| Preset | Use it for |
|---|---|
| Balanced | Most talking-head videos, lectures, podcasts and calls. Strong reduction with a natural voice. |
| Strong | Loud fans, wind, street or crowd noise, where some voice colour is a fair price for silence behind it. |
| Gentle | Recordings where a little room sound should stay, such as music lessons or interviews on location. |
| Hum only | A clean recording with only a mains buzz. Removes 50/60 Hz and its harmonics and touches nothing else. |
| Voice enhance | Narration and online classes: removes noise and hum, adds presence and evens out loud and quiet parts. |

Meeting and interview recordings
Take the air conditioning, keyboard clicks and café chatter out of a Zoom or Teams recording or an on-location interview.

Frequently Asked Questions
How do I remove background noise from a video online?
Choose your video, listen to the cleaned preview, adjust the strength or pick a preset, and click Remove noise. The tool cleans the sound track and puts it back into the same video; the picture is copied without re-encoding, so it looks exactly as before. Download the result, with no watermark.
Can I remove background noise from an audio file too?
Yes. Drop an MP3, WAV, M4A, OGG, Opus or FLAC file and save the cleaned version as MP3 or as lossless WAV.
What kinds of noise can it remove?
Steady noise such as air conditioners, fans, computer hum, hiss and traffic is removed almost completely. Changing noise such as wind, keyboard clicks, dishes and distant chatter is reduced strongly. Electrical hum at 50 or 60 Hz is removed with the Hum only option. Music and a second person talking close to the microphone are treated as sound to keep.
Will it make my voice sound robotic?
The Balanced preset is tuned to keep the voice natural. If you hear a watery or thin sound, lower the strength or choose Gentle, which leaves a little room sound in. Use the Before/After switch to compare the same moment instantly.
Is my file uploaded?
No. The AI model runs inside your browser and the file never leaves your device. That also means there is no upload wait for large videos.
Is it free?
You can clean 15 minutes of audio or video a day for free, and the preview is always free. A longer recording is not blocked: its first 15 minutes are cleaned for free so you can hear the result. Pro gives you 20 times as much every day, and Premium has no limit. There is no watermark on any plan.
Does it change the video quality?
No. The video stream is copied as it is, so the resolution, frame rate and picture quality are unchanged. Only the sound is cleaned and re-encoded at a high bitrate.
How long does it take?
The first time, the browser downloads the noise removal model (about 18 MB, cached afterwards). After that a few minutes of audio usually takes under a minute on a desktop computer and longer on a phone. The video picture itself takes almost no time because it is not re-encoded.
What is the difference between this and Remove Audio from Video?
Remove Audio from Video deletes the whole sound track and leaves a silent video. This tool keeps the voice and removes only the background noise.
