Galaxy S25: How to Use Audio Eraser on Your Videos

Quick summary: Audio Eraser uses Galaxy AI to separate the sounds in your videos (voices, wind, nature, background noise) so you can turn each one down, up or off. It needs One UI 7 or newer. When I made this video it was only on the Galaxy S25 series, but it may come to other phones.

Step by step

1. Open the Gallery app and open a video.
2. Tap the Galaxy AI button (the sparkles icon) at the bottom. It analyzes the audio and opens Audio Eraser.
3. Preview: play the video, and tap the original audio button at the top to compare before and after.
4. Tap Auto to have it turn down the sounds it thinks you don’t want. On my skate park video, Auto cut the wind by 100%, nature and background noise by about 90%, and left my voice at 100%.
5. Or adjust each sound yourself: tap a sound type, like Voices or Noise, and drag the slider. Go down to -100 to remove it completely, or turn it up to make it louder. Tap Mute to silence a sound.
6. Tap Save a copy. The new version is saved to your Gallery, and your original stays untouched.

What it can pick out

Depending on the video, you’ll see categories like voices, noise, wind, nature and background noise. It also works with multiple voices, so you can mute someone talking loudly behind you. On a video of kids screaming with excitement, Auto toned the screams way down. Sometimes you’ll want to keep sounds like that, and you can turn them back up.
