What if you can erase the background noise in your videos?
If technology had a magic wand, it would probably come in the form of a smartphone.
It certainly felt that way when Samsung’s product marketing manager, MJ Marfori, magically erased the voices of people conversing in a video she took during her last vacation. Only the sound of the wind was left in the video after she made a few swipes on the screen. She did this in a matter of seconds during the “Samsung Unpacked” event at Samsung Hall in SM Aura.
Audio Eraser is part of the new AI offerings from Samsung, which rolled out its flagship Galaxy S25 phones last month. This, to me, is a game changer because I can already imagine the possibilities—such as removing screaming voices at a concert or the sound of dogs barking while trying to record a video on the phone.
The Audio Eraser can isolate different sound elements and group them into wind, speech, and noise. You can lower or mute each element while increasing the volume of others. It’s a sound studio that fits in the palm of your hand.
We have yet to see how effective it will be in a real-life setting. Will it be able to distinguish the screams of fans from the voice of a singing artist? But it’s exciting to think about having cleaner audio the next time we upload our fancams.
The Circle to Search feature has been expanded to include audio. Whatever song is playing at the moment can now be identified by the phone. It functions just like Shazam, but does not store a record or create a playlist of the songs you’ve searched for.
Seamless integration
This is consistent with what I’ve noticed about the AI additions from last year. They have mirrored third-party apps, focusing on certain features that make them practical for daily use while leaving out niche aspects. Voice Recorder, for example, can transcribe an audio conversation, generate a summary, and create notes—just like Otter—but lacks the sharing capabilities of the latter.
However, Galaxy AI has an edge in seamless integration with the phone’s core features. The Voice Recorder’s transcription can be instantly translated into multiple languages without switching apps, keeping the user within Samsung’s ecosystem.
Integration remains its strength, especially with the introduction of the Personal Data Engine in One UI 7, the software interface built into the S25’s operating system. Its purpose is to suggest actions you can take with text or graphics based on the apps already installed on your phone. For example, if you have notes about an upcoming trip, AI can edit them for spelling, grammar, and tone or even change the format to suit what you need before sharing them with your companions.
At “Unpacked,” Samsung said you can talk to it like a friend because it can break down sentences and provide exactly what you need, using the apps available on your phone. For example, it can find specific concert photos from two years ago based on your descriptions and the timeline you give it.
The Now Brief feature aims to personalize your experience, offering morning updates about events nearby that may interest you and an evening summary of what you’ve accomplished during the day.
And of course, the camera. AI has changed the selfie game at concerts. I no longer worry about uneven lighting when taking selfies with the stage behind me because I know my phone will automatically adjust the exposure for me. There will be even more enhancements to this experience, including pro-grade video quality. It offers less noise at night and more detailed macro shots.
