Think about capturing a busking efficiency, solely to have automobile horns overpower the music — or filming a vlog in a café the place ambient noise makes conversations practically unattainable 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 doable due to the proactive efforts of Samsung Analysis and the Cellular eXperience (MX) Enterprise at Samsung Electronics.
Samsung Newsroom sat down with audio expertise consultants from the AI Answer Workforce at Samsung Analysis to be taught extra in regards to the growth of this modern function.

Supply Detection: The Way forward for Subsequent-Technology Audio Expertise
Audio Eraser permits customers to regulate sounds inside a video by eradicating undesirable noise and enhancing the audio they need to spotlight. The function shortly scans a video to detect and separate sounds by kind, and can be utilized not solely on clips recorded by the consumer but in addition on movies which have been shared or obtained.
Simply as Object Eraser improved picture enhancing 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.

Creating Sound Supply Detection and Separation Fashions
Audio Eraser acknowledges six forms of sound — voices, music, wind, nature sounds, crowd noise and ambient noise. Utilizing sound supply detection expertise, the function shortly identifies what sounds are current and the place they happen in a video. Then, via sound supply separation expertise, it isolates and classifies every sound into distinct classes.
To construct AI fashions able to detecting and isolating these audio sorts, the analysis group started by amassing a sturdy 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 Workforce at Samsung Analysis. “Apart from refining our wind simulation expertise, we enhanced our dataset by recording precise wind sounds outside each time robust winds occurred — even after work or on weekends.”
As well as, the group devoted intensive time to bettering the efficiency of the sound supply separation mannequin by rigorously reviewing numerous video clips a number of instances.
“Every developer in contrast and analyzed greater than 1,000 audio samples each week underneath a wide range of circumstances,” mentioned Jiwon Kim. “By way of 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 affords an enhanced consumer expertise with real-time enhancing and improved privateness safety. Samsung’s long-standing experience in creating aggressive on-device AI capabilities throughout numerous options performed a key position in Audio Eraser’s success.
“We centered on creating AI fashions and algorithms able to quick, on-device processing,” mentioned Hosang Sung. “Quite a lot of effort went into creating an optimized AI resolution that runs easily with low energy consumption.”
Supported by a powerful AI analysis infrastructure, Samsung Analysis continues to strengthen its capabilities in superior audio applied sciences.
“We’re dedicated to creating next-generation options that elevate the usability of cell gadgets,” mentioned Hoonyoung Cho, Vice President and Head of the AI Answer Workforce at Samsung Analysis. “By way of sound management and audio enhancement applied sciences, we goal to ship a really selective and customized 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 example, when enhancing video and audio concurrently, playback wanted to stay easy and uninterrupted. Moreover, processing movies longer than an hour required specialised expertise able to finishing the duty inside the similar timeframe.
To deal with 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 growth of the Galaxy Buds3 collection (Buds3, Buds3 Professional). Because the wants for listening in noisy environments grows — for all the pieces from music and media experiences to listening to clearer cellphone calls — Energetic Noise Cancellation (ANC) has turn out to be an more and more important function in wi-fi earbuds. Samsung raised the bar by creating its personal Adaptive ANC expertise. The Galaxy Buds3 collection adapts to the becoming circumstances of various customers and modifications in match attributable to extended put on to ship optimized ANC efficiency.
Since earbuds are worn immediately 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 totally different {hardware} circumstances,” mentioned Kyoungbo Min. “By way of intensive simulations, we ready an answer that might be shortly tailored to any chipset or machine. 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 subject. With Audio Eraser making full use of sound supply separation, the corporate is getting ready to increase into a variety of recent purposes. The continuing evolution of Galaxy AI is anticipated to ship much more sensible and intuitive options for shoppers.
1 Outcomes might fluctuate per video relying on how sounds current within the video. Samsung Account login required. Sure forms of sound will be detected similar to voices, music, wind, nature, crowd and noise. The precise sound detection might fluctuate relying on audio supply and the situation of the video. Accuracy of outcomes shouldn’t be assured.
