- 2Pick a strength: Full, Strong or Gentle.
- 3Click “Remove noise” and download the cleaned file.
How it works
The cleaning is done by RNNoise, a small neural network built to separate speech from noise. It works best on spoken voice; music and singing can sound processed.
Choosing a strength
“Full” removes as much noise as possible. “Strong” and “Gentle” blend a little of the original sound back in, which keeps voices more natural in quiet rooms.
Videos stay videos
When you choose a video, only the soundtrack is cleaned. The picture is copied untouched and you get the same video with clearer sound.
