Remove Background Noise from Video Free

Clean audio without leaving your video editor behind

Most free noise removers only take an audio file. You export the sound, clean it, then line it back up with your video by hand. This tool takes the video itself. It pulls the audio out, removes the background noise, and puts the clean audio back into the same video, so you get an MP4 that is ready to post.

The picture is not re-encoded. The video stream is copied bit for bit, so there is no quality loss and no wait for a render. The new audio stays in sync from the first frame to the last.

How the noise removal works

The cleaning is done by RNNoise, an open-source neural network trained to tell a speaking voice apart from the noise around it. It is good at steady sounds: a laptop fan, an air conditioner, traffic outside the window, or the hiss of a cheap microphone. It runs on your own device, which is why there is no upload, no account and no limit.

Strong noise removal can make a voice sound thin. The strength slider blends the cleaned audio with the original, so you can keep a little room sound if the full clean feels too dry. Switch between Original and Cleaned while the video plays to hear the difference at the same moment.

Tips for cleaner audio next time

Noise removal works best when the voice is much louder than the noise. Record close to the microphone, turn off fans you can control, and avoid hard, empty rooms that echo. A phone held at arm's length in a quiet room usually sounds better than a far-away camera in a noisy one.

Once the audio is clean, the next slow job is usually editing: cutting the pauses, the false starts and the takes you didn't like. Stitch does that part for you. Upload your raw clip and it removes the dead air and bad takes automatically, so you can post faster.
