Samsung Audio Eraser, and Other Ways to Clean Android Recordings

Most noise tools treat noise as one thing to turn down. Audio Eraser is a source separator: it analyses the audio, identifies what's in it, and lets you change the level of each part on its own. Samsung lists six sound types it can detect:

• Voices: relatively clear voices of the people around you.
• Wind: outside wind or gusts.
• Music: background music.
• Nature: sounds such as waves and birds.
• Crowd: groups of people, cheering or applause.
• Noise: general unclassified noise.

You only see the types it finds in your clip, and Samsung says detection varies with the recording. There's also an Auto option that lets Galaxy AI reduce noise for you, and a Hear original button that plays the untouched audio for comparison. Because each type has its own slider, you can also do the reverse of noise removal, such as lowering voices to keep the music and wind of a beach clip.

Samsung is candid about limits: results depend on how the sounds overlap, short sounds may go undetected, and accuracy isn't guaranteed. A dog barking once during a sentence, for instance, may survive. It needs a Samsung account, and Samsung currently charges nothing for it, while reserving the right to charge for future features.

Samsung says Audio Eraser works on select Galaxy phones and tablets, but its regional support pages don't agree on the oldest model that gets it, so we won't name a cut-off. Samsung Newsroom says the feature was first introduced on the Galaxy S25 series. So the practical test is your own phone: if you have Galaxy AI, look for Audio eraser under Gallery's Edit, Audio menu, and if it isn't there, update the phone first. Samsung also points to Settings > Galaxy AI > Audio eraser for the feature's own page.

Where it appears has widened with each generation:

• Gallery video editor: the original home of the feature, first on the S25 series and since then on other Galaxy AI models.
• Video Player, Voice Recorder, Samsung Notes and Phone-app call recordings: added with the One UI 8 expansion, in Samsung Newsroom's words, and listed on Samsung's US support page.
• The Quick panel: on the Galaxy S26 series, Audio Eraser can work in real time on videos you're watching in supported apps, with a Strength slider and a Voice focus switch. Samsung's US page describes the same Quick panel control for full-screen YouTube.

On phones with the One UI 8 expansion, open the recording in Voice Recorder and tap the Audio eraser icon, an eraser with a sound wave. Samsung says it then reduces other noise and emphasises voices automatically; there are no per-type sliders in these steps. The same icon appears for videos in Video Player, in Samsung Notes recordings and for recorded calls in the Phone app.

Here's the catch behind the Bing question "samsung voice recorder noise eraser save recording after effect": Samsung's instructions stop at tapping the icon. They don't describe saving a cleaned copy of a voice memo, and Samsung Newsroom describes the Voice Recorder version as a playback adjustment. So test before you rely on it. Share the recording to yourself, or open it in another app, and listen. If the noise is back, the clean-up only applied while you played it in Voice Recorder, and you need the export route in section 07 for a cleaned file you can send.

In Gallery, Samsung's steps end with Save copy, so the edited video is saved as a new file and the original stays where it was. Hear original only previews; it doesn't undo anything. If you don't like the result, delete the copy and start again from the original. Samsung's pages don't describe an option to overwrite the original from Audio Eraser, which is the safest design for this kind of edit.

If you're tidying up afterwards, check you're deleting the copy, not the original. In Gallery both appear side by side, and a quick play of each settles which one has the noise.

Samsung publishes no maximum length and no processing time for Audio Eraser, and doesn't say whether the analysis runs on the phone or online. The phone analyses the clip before the sliders appear, so a longer file means a longer wait, and older models may take longer than the newest phones.

Three habits keep it manageable. Trim the video to the part you need before you open Audio Eraser. Keep the phone plugged in and the screen on while it works. And for anything longer than a few minutes, or anything that matters, move the file to a computer or an upload tool from the start, where you get more control and a predictable result.

Pixel 8 and later: Google Photos has Audio Magic Eraser for videos. Open the video, tap Edit, go to the audio tools, choose Audio Eraser, then use Auto or the per-sound sliders and tap Save copy. Google says it isn't available on tablets.

Everything else, the export route: export the file from your recorder, usually as M4A or WAV, and clean it elsewhere. Your options:

• Adobe Podcast Enhance Speech in the browser: free for up to 1 hour of audio a day, with uploads of up to 30 minutes, audio only. Premium adds video and a strength control. See our Enhance Speech guide.
• Auphonic: 2 hours of processing a month on a free account, with separate control over noise and reverb removal.
• Cleanvoice: 30 minutes of free credit on sign-up, and its FAQ says it removes wind noise as well as background noise.
• Audacity on a computer, free and open source, if you'd rather do it by hand: see our Audacity guide.
