Frequently asked questions
What kind of noise does it remove?
Steady, constant noise: hiss, hum, fans, air conditioning, computer noise and distant traffic. It cannot remove sudden sounds such as a dog barking, or music.
Why does Strong sometimes sound watery?
Aggressive noise reduction removes parts of the voice that resemble the noise, which causes a slightly metallic sound. Use the lightest setting that removes enough.
Can it remove background music?
No. Music is not steady noise. To separate a voice from music, use the AI Vocal Remover.
Is this AI noise removal?
No, it is a classic signal-processing filter that runs entirely in your browser, which keeps it free and private. It works well on steady noise.
Is my file uploaded?
No. Everything happens on your device.
Does it work on phones?
Yes, and because only audio is processed it finishes quickly.
