Think about capturing a busking efficiency, solely to have automotive horns overpower the music — or filming a vlog in a café the place ambient noise makes conversations practically unimaginable to listen to.
Audio Eraser, launched within the Galaxy S25 collection, was designed to handle such conditions by decreasing undesirable background noise and enhancing desired sounds to assist customers create extra immersive movies.1 Galaxy AI options like Audio Eraser — developed with a deep understanding of consumer wants — was made potential because of the proactive efforts of Samsung Analysis and the Cellular eXperience (MX) Enterprise at Samsung Electronics.
Samsung Newsroom sat down with audio expertise specialists from the AI Answer Crew at Samsung Analysis to study extra in regards to the improvement of this modern function.

Supply Detection: The Way forward for Subsequent-Era Audio Know-how
Audio Eraser permits customers to regulate sounds inside a video by eradicating undesirable noise and enhancing the audio they need to spotlight. The function rapidly scans a video to detect and separate sounds by kind, and can be utilized not solely on clips recorded by the consumer but additionally on movies which were shared or obtained.
Simply as Object Eraser improved picture modifying and value with its debut within the Galaxy S21 collection, Audio Eraser was developed to ship a extra superior and seamless multimedia expertise throughout each audio and video.

Growing Sound Supply Detection and Separation Fashions
Audio Eraser acknowledges six varieties of sound — voices, music, wind, nature sounds, crowd noise and ambient noise. Utilizing sound supply detection expertise, the function rapidly identifies what sounds are current and the place they happen in a video. Then, by means of sound supply separation expertise, it isolates and classifies every sound into distinct classes.
To construct AI fashions able to detecting and isolating these audio varieties, the analysis group started by accumulating a strong set of coaching information. They simulated a variety of real-world video recording situations to generate various audio datasets — and even went into the sphere to seize on a regular basis sounds firsthand.
“Wind was notably difficult to work with,” mentioned Hejung Yang from the AI Answer Crew at Samsung Analysis. “Moreover refining our wind simulation expertise, we enhanced our dataset by recording precise wind sounds outdoor each time robust winds occurred — even after work or on weekends.”
As well as, the group devoted intensive time to enhancing the efficiency of the sound supply separation mannequin by fastidiously reviewing numerous video clips a number of instances.
“Every developer in contrast and analyzed greater than 1,000 audio samples each week underneath quite a lot of circumstances,” mentioned Jiwon Kim. “By steady experimentation, we labored to determine the simplest sound supply separation mannequin to make sure constant, high-quality outcomes.”

Delivering a New Consumer-Centric Listening Expertise
As Audio Eraser runs on-device, it presents an enhanced consumer expertise with real-time modifying and improved privateness safety. Samsung’s long-standing experience in growing aggressive on-device AI capabilities throughout numerous options performed a key position in Audio Eraser’s success.
“We targeted on growing AI fashions and algorithms able to quick, on-device processing,” mentioned Hosang Sung. “An excessive amount of effort went into creating an optimized AI resolution that runs easily with low energy consumption.”
Supported by a robust AI analysis infrastructure, Samsung Analysis continues to strengthen its capabilities in superior audio applied sciences.
“We’re dedicated to growing next-generation options that elevate the usability of cellular gadgets,” mentioned Hoonyoung Cho, Vice President and Head of the AI Answer Crew at Samsung Analysis. “By sound management and audio enhancement applied sciences, we goal to ship a really selective and personalised listening expertise.”
Built-in Collaboration With Product Improvement Groups
Turning superior analysis right into a consumer-ready resolution introduced a brand new set of challenges. As an illustration, when modifying video and audio concurrently, playback wanted to stay clean and uninterrupted. Moreover, processing movies longer than an hour required specialised expertise able to finishing the duty throughout the identical timeframe.
To handle these challenges, Samsung Analysis and the MX Enterprise labored collectively — from proposing user-centric concepts to repeatedly testing software program optimization methods and evaluating audio high quality. Collectively, they explored a number of approaches to find out the simplest resolution.
The cross-functional collaboration had already confirmed profitable within the improvement of the Galaxy Buds3 collection (Buds3, Buds3 Professional). Because the wants for listening in noisy environments grows — for every little thing from music and media experiences to listening to clearer telephone calls — Energetic Noise Cancellation (ANC) has turn into an more and more important function in wi-fi earbuds. Samsung raised the bar by growing its personal Adaptive ANC expertise. The Galaxy Buds3 collection adapts to the becoming circumstances of various customers and adjustments in match brought on by extended put on to ship optimized ANC efficiency.
Since earbuds are worn straight within the ear, shut coordination between {hardware} and software program groups was important to finalize product specs and fine-tune the ANC expertise.
“We developed a number of algorithms prematurely to accommodate completely different {hardware} circumstances,” mentioned Kyoungbo Min. “By intensive simulations, we ready an answer that might be rapidly tailored to any chipset or system. The event course of concerned iterative revisions and enhancements, however the shut collaboration between superior analysis and product groups helped speed up commercialization.”
Sound supply separation is a core space of next-generation audio expertise, and Samsung continues to advance its foundational improvements on this discipline. With Audio Eraser making full use of sound supply separation, the corporate is getting ready to broaden into a variety of recent functions. The continuing evolution of Galaxy AI is predicted to ship much more sensible and intuitive options for shoppers.
1 Outcomes could fluctuate per video relying on how sounds current within the video. Samsung Account login required. Sure varieties of sound could be detected comparable to voices, music, wind, nature, crowd and noise. The precise sound detection could fluctuate relying on audio supply and the situation of the video. Accuracy of outcomes will not be assured.
