About replacing the audio of a video

Replace the sound of a video with your own music, a doubled voice or a voice-over you record on the spot, right in your browser. You hear the result before you download it.

Music or a voice-over instead of the sound

Remove the background noise, the wind or a protected song, and put your own sound in its place: royalty-free music, a dub, or a voice-over recorded with the microphone while the video plays. Or keep the original sound in the background, lower.

Timed just right

Choose when the sound starts in the video and skip the beginning of the track if you need to. Listen to the result before you download. A short sound can loop, and a long one stops with the video, with a fade out.

The picture keeps its quality

Only the sound changes: the picture is copied as it is, with no re-encoding. It is fast, and the video loses nothing.

Nothing is uploaded

The video and the sound stay in your browser. They are neither sent nor saved.
