How to remove background noise from a video
5 min read
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, free
- Open the video noise remover and drop in your MP4, MOV 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 preview first; your paid download is the full video with the cleaned audio muxed back in and the picture left untouched. Longer files and batch processing are part of CleanNoise Pro.
Why on-location video is so noisy
Camera and phone microphones are omnidirectional and 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.
