Reduce background noise in audio locally: rumble filter, soft noise gate, normalization and MP3 export.
Exact settings
This is not AI noise removal and not voice separation from music. For speech with steady background noise, start with a 3-5% threshold and reduce strength if words are cut off.
How to use it
Add a recording, choose background reduction strength and rumble filter frequency. Basic Web Audio cleanup runs on your device.
Recommended settings
This is not AI voice isolation. It works best for hum, hiss and quiet gaps between words. Lower threshold or strength if speech becomes choppy.
