Clean up a voice recording: common questions

What kind of noise does it remove?

Steady noise that's there the whole time: electrical hum, hiss, a fan, a fridge, air conditioning, computer whir. It learns what that noise sounds like from the quiet moments between words. Sudden sounds like a dog barking, a door or other people talking are part of the recording and stay.

Why does my voice sound watery?

That's the noise gate working too hard. Choose Reduce a little and try again. Recordings where the noise is nearly as loud as the voice are hard to clean without some of that effect.

Is my recording uploaded?

No. It's decoded and cleaned by your browser on your computer, and never sent to this website or anyone else.

Why WAV and not MP3?

Browsers can read MP3 but have no built-in way to create one. WAV keeps full quality and opens almost anywhere. It's larger, about 10 MB a minute in stereo.

Does it replace Krisp or Adobe Podcast?

For cleaning up a recording you already have, often yes, and it's free. Those apps also use AI models to remove noise live during calls and to handle changing noise, which needs more than a browser page.
