Cleaned and mixed on your device. Nothing is uploaded.
Voice and background are separated using the stereo center/side technique — instant and fully private. Works best on stereo recordings; on mono files, use the noise and volume controls. For video, the picture is untouched.
Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed entirely inside your browser. Your files never leave your device or get sent anywhere.
What can I control?
Four sliders: Voice level, Background/music level, Noise reduction, and Overall volume — plus checkboxes to keep or remove the voice and background entirely, and an optional trim. Press Preview to hear 20 seconds of your mix before creating the full file.
What kinds of noise does it remove?
Constant background noise: hiss, hum, fans, air-conditioning, static and room rumble. Sudden sounds (a door slam, a cough) are not the target of this filter.
Does it work on videos too?
Yes — drop a video and only its sound is changed; the picture is untouched and stays at original quality.
How does the voice/background separation work?
On stereo recordings the voice usually sits in the middle of the stereo image, so it can be adjusted separately from the sides (music and ambience) — instantly, with no AI download. On mono files, use the noise and volume controls instead.
