Remove Background Noise from Audio & Video

How to clean a speech recording

1. Choose audio or video from your device. The tool processes the whole selected recording. For a short test, cut the audio or trim the video first.
2. Set reduction strength and run the tool. The slider goes from 25 to 100% in 5-point steps. Allow the processing resources to load on first use.
3. Compare Original and Cleaned. Switch versions on the same passage, listening to both quiet words and the background between them. This comparison uses the completed result.
4. Adjust and rerun if needed. Lower the strength if consonants disappear or the voice sounds artificial. Each run starts from the selected source, rather than stacking reductions on the previous result.
5. Download the version you prefer. Save the WAV. For a compatible video source, a video download is also prepared; check its sound before sharing.

Example: narration recorded beside a fan

In a two-minute tutorial narration, listen to a pause followed by a softly spoken sentence. At 100%, the fan may become quieter while the sentence loses detail. Try 75% or 50%, process again and compare those same words. Keep the version with intelligible speech, even if some fan sound remains.

A quieter pause alone does not prove a better recording. Check sentence endings, breaths and soft consonants at a similar playback volume. Keep the original file for later adjustments.

Use the tool that matches the problem

To split singing from instruments, use the vocal remover. To shorten low-volume gaps, use Remove Silence. For a completely silent video, remove its audio track. Browse all free audio and video tools for other edits.
