Frequently asked questions
What kind of noise does it remove?
Steady noise best: hiss, fan and air-conditioner hum, electrical buzz and room noise. Sudden sounds like a door slam or speech in the background stay.
Will the voice sound worse?
At Light and Medium the voice stays natural. Strong removes more noise but can make speech sound slightly “underwater” — try Medium first.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
