Audio Magic Eraser Pixel: How to Use It

Audio Magic Eraser is a Google Pixel feature that separates a recording into different sound layers and lets you remove or reduce unwanted noises, like wind, traffic, or a loud crowd, while keeping the main audio intact. You can use it on videos and voice recordings saved on your Pixel. Before you start, make sure your Pixel is updated to a recent Android version, since the tool is built into the Photos and Recorder apps.

What You’ll Need

• A Google Pixel phone (Pixel 8 or newer for the full version in Photos; some older models have a limited version).
• A video or voice recording saved on the device.
• The Google Photos app (preinstalled) or the Recorder app (preinstalled on Pixel).
• An internet connection is not required; everything runs on the phone.

Step-by-Step

For a video in Google Photos

1. Open the Google Photos app on your Pixel.
2. Tap the video you want to clean up to open it in full screen.
3. Tap the Edit icon (the slider/pencil symbol) at the bottom.
4. Look for the Audio Eraser button. It appears as a small waveform icon with a slash through it, usually in the row of tools below the video. If you don’t see it, tap the three-dot menu and check for “Audio Eraser” there.
5. Tap Audio Eraser. The phone will analyze the audio for a few seconds. You will see a waveform with color-coded segments: usually yellow for voices, red for noise, and blue for other sounds.
6. To remove a specific noise, tap the red or blue segment on the waveform. A slider appears for that sound category.
7. Drag the slider to the left to reduce the noise, or all the way to zero to remove it completely. You can also tap the category name (like “Wind” or “Crowd”) to mute it entirely.
8. Use the play button to preview the result. Adjust the sliders until the unwanted sound is gone but the main audio still sounds natural.
9. Tap Save copy at the top right. The original video stays untouched, and a new edited copy is saved in your library.

For a voice recording in the Recorder app

1. Open the Recorder app on your Pixel.
2. Tap the recording you want to clean up.
3. Tap the Edit (pencil) icon.
4. Tap Audio Eraser in the editing toolbar.
5. Wait for the analysis to finish. You will see the same color-coded waveform.
6. Tap the noise segments (red or blue) and drag the slider down to reduce them.
7. Preview with the play button, adjust as needed, then tap Save.

Common Mistakes

• Expecting it to work on every video. Audio Magic Eraser only works on videos recorded with the Pixel camera app, not on downloaded clips or videos from other apps.
• Dragging the slider too far. Reducing a noise to zero can also remove the reverb or room tone that makes the main voice sound natural. Start with a small reduction and listen.
• Confusing the color codes. Yellow is not always the voice you want to keep. If you have two people talking, both may be yellow. Listen before muting anything.
• Forgetting to save a copy. If you tap the back arrow without saving, your changes are lost. Always hit “Save copy” or “Save” when you are happy with the result.
• Using it on a very short clip. The tool needs a few seconds of audio to analyze. Clips under 2 seconds may not show the option.

Tips

• Use headphones when previewing. Phone speakers can mask the difference between the original and the cleaned audio.
• If the noise is constant (like a fan or traffic), the tool usually detects it automatically. If not, tap the waveform manually to select the exact moment where the noise is loudest.
• For wind noise, try reducing the “Wind” category specifically instead of muting the whole red layer. This keeps the voice clearer.
• Combine Audio Magic Eraser with the regular video trim tool. Cut out the worst parts first, then clean the remaining audio.
• If you are recording a new video and know you will have background noise, record a few seconds of just the noise before speaking. This gives the eraser a clean sample to identify and remove.

Troubleshooting

• Audio Eraser button is missing. Check that your Pixel is running Android 14 or later. If it is, make sure the video was recorded with the Pixel’s camera. Videos from WhatsApp, Instagram, or downloaded files won’t have the option. Also, restart the Photos app or the phone.
• The tool says “Cannot process this video.” The video may be too long (over 10 minutes) or in an unsupported format. Try trimming it shorter first, or convert it to MP4 using a file converter app.
• No sound layers appear after analysis. This happens when the audio is very quiet or the noise is too uniform. Increase the volume of the video in the editor, then try again. If it still fails, the recording may not have enough distinct sound layers to separate.
• The voice sounds robotic or warbled after editing. You reduced the noise too much. Undo the edit (tap the undo arrow) and apply a gentler reduction, around 30-50% instead of 100%.
• Changes are not saving. Make sure you have enough free storage on the phone. Saving a copy creates a new file, which needs space. Check your storage in Settings > Storage and delete some files if needed.
• Audio Eraser works in Photos but not in Recorder. The Recorder app’s version is only available on Pixel 8 and newer. If you have an older Pixel, use the Photos app on videos instead, or use the Recorder’s built-in “Transcript” cleanup feature which removes filler words but not background noise.

Frequently Asked Questions

Does Audio Magic Eraser work on music or songs?

It can reduce background noise in a video that has music playing, but it is not designed to isolate or remove music itself. It works best on speech and distinct noise sources like wind, traffic, or applause.

Will it work on videos I recorded with a different phone?

No. The tool checks the video metadata and only processes clips recorded with the Pixel camera app. Videos from other phones or apps will not show the Audio Eraser option.

Can I undo the edit after saving?

Yes. The original file is never overwritten. You can delete the edited copy and re-edit the original anytime. If you want to tweak the saved copy, open it in Photos and run Audio Eraser again.

Does Audio Magic Eraser work offline?

Yes, all processing happens on the device. No internet connection is needed, and your audio is never uploaded to a server.

Why does the tool only show one color on the waveform?

If the recording has only one dominant sound (like a single voice with no background noise), the tool may show just one layer. In that case, there is nothing to erase, which is why you only see one color.

Is Audio Magic Eraser available on Pixel 7 or older?

The full version with manual sliders is on Pixel 8 and newer. Pixel 7 and 7 Pro have a basic version that can reduce noise but with fewer controls. Pixel 6 and older do not have the feature at all.
