How to remove background noise from a video
Noisy location audio (wind across the mic, traffic, an air conditioner, a chatty café) can ruin an otherwise great video. You don't need to re-shoot. Because the noise on a video's audio track is usually steady, you can strip most of it out automatically.
Remove video noise online
- Open the video noise remover and drop in your MP4, MOV, MKV or WebM file.
- CleanNoise reads the video's audio track, profiles the background noise and suppresses it while keeping voices clear.
- Preview the cleaned result and download it in one click, with no settings.
You get a free 30-second preview first, with no sign-up. The full download is $0.99 per file up to 30 minutes ($1.99 for 30 to 60 minutes): the same video format you uploaded (an MP4 stays an MP4), with the cleaned audio and the picture left untouched. Files are processed one at a time; for regular use there are credit packs and CleanNoise Pro.
Why on-location video is so noisy
Phone microphones are typically omnidirectional, and built-in camera microphones are often far from the speaker, so they pick up everything in the room. That's why the same scene sounds fine to your ears but noisy on playback. A noise remover rebalances things by pulling down the constant background layer.
Get better results
- Compare the cleaned preview against the original before you pay, so you decide if it sounds natural.
- For echoey rooms or muffled on-camera mics, switch on Remove echo / reverb for extra restoration.
- For wind specifically, cleanup helps, but a windscreen at record time helps more.
- If you only need the sound, our extract audio from video tool pulls a clean audio file straight out.
