Isolate the voice in a noisy video with Quick tools
by DepCut Team
Published: October 30, 2026
A good take can lose to a humming fan, street traffic or a music bed that was louder than you remembered. The Isolate voice card in Quick tools takes the video file and returns the same picture with the speech kept and the music and background noise removed.
What the tool does
The dialog describes it in one line: it removes the music and background noise and keeps the speech. It also says it uses credits, by the length of the video.
Behind that line, DepCut pulls the audio out of your video and sends it to a hosted voice isolation step. The cleaned track then replaces the clip's own sound, the video renders, and the finished file downloads.
Isolate the voice
- Open the Projects page and find the Quick tools row.
- Click Isolate voice.
- Drop a video onto the dashed box, or press Choose a file.
- Read the credits note in the dialog, then press Run.
- Follow the stages: Uploading, Extracting audio, Isolating the voice, Adding the new audio, and Rendering.
- When the dialog says "Done", your download of the video should have started.
Keep the dialog open until then. The file arrives on its own when the run finishes.
What stays in your list
Each run leaves its project in your Projects list. In the Isolate voice project, the original clip is muted and the cleaned speech sits on the soundtrack as a clip named after your file, ending in "voice.mp3". The cleaned clip starts where the video starts.
Open that project when you want to go further. You can lower the speech, add a fade, place a title, or lay in a new music track, and then export as usual. The original file on your computer is untouched.
Get a clean result
- Test a short stretch first. Credits follow the length of the video, so a ten-second clip tells you how the voice comes out before you spend on a long recording.
- Listen to the whole download once before you publish. Check the quiet pauses and the ends of sentences.
- Add music back on purpose. The tool removes the music that was in the file. If you want a bed under the speech, open the run's project and choose one from AI Gen, then Audio, then Music.
- Use footage and music you have the right to use.
When to reach for it
Isolate voice suits a talking clip with a single noise problem. A phone interview recorded beside a fan, a street interview with traffic behind it, and a talking clip with a music bed you now want gone are all good fits.
If the opposite is true and you want the music without the talking, use Isolate music from the same row.
