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 inconceivable to listen to.
Audio Eraser, launched within the Galaxy S25 sequence, was designed to deal with such conditions by lowering 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 because of the proactive efforts of Samsung Analysis and the Cell eXperience (MX) Enterprise at Samsung Electronics.
Samsung Newsroom sat down with audio expertise specialists from the AI Answer Staff at Samsung Analysis to be taught extra concerning the growth of this revolutionary function.

Supply Detection: The Way forward for Subsequent-Technology Audio Expertise
Audio Eraser allows customers to regulate sounds inside a video by eradicating undesirable noise and enhancing the audio they wish 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 have been shared or acquired.
Simply as Object Eraser improved picture enhancing and value with its debut within the Galaxy S21 sequence, 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 kinds 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 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 workforce started by accumulating a strong set of coaching information. They simulated a variety of real-world video recording situations to generate numerous audio datasets — and even went into the sector to seize on a regular basis sounds firsthand.
“Wind was significantly difficult to work with,” stated Hejung Yang from the AI Answer Staff at Samsung Analysis. “In addition to refining our wind simulation expertise, we enhanced our dataset by recording precise wind sounds outside each time sturdy winds occurred — even after work or on weekends.”
As well as, the workforce devoted in depth time to bettering 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,” stated Jiwon Kim. “By means of steady experimentation, we labored to determine the best sound supply separation mannequin to make sure constant, high-quality outcomes.”

Delivering a New Person-Centric Listening Expertise
As Audio Eraser runs on-device, it gives 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 varied options performed a key position in Audio Eraser’s success.
“We centered on creating AI fashions and algorithms able to quick, on-device processing,” stated Hosang Sung. “Quite a lot of effort went into creating an optimized AI answer 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,” stated Hoonyoung Cho, Vice President and Head of the AI Answer Staff at Samsung Analysis. “By means of sound management and audio enhancement applied sciences, we purpose to ship a really selective and personalised listening expertise.”
Built-in Collaboration With Product Improvement Groups
Turning superior analysis right into a consumer-ready answer introduced a brand new set of challenges. As an illustration, when enhancing 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 similar timeframe.
To handle these challenges, Samsung Analysis and the MX Enterprise labored collectively — from proposing user-centric concepts to repeatedly testing software program optimization strategies and evaluating audio high quality. Collectively, they explored a number of approaches to find out the best answer.
The cross-functional collaboration had already confirmed profitable within the growth of the Galaxy Buds3 sequence (Buds3, Buds3 Professional). Because the wants for listening in noisy environments grows — for all the things from music and media experiences to listening to clearer cellphone calls — Lively Noise Cancellation (ANC) has turn into an more and more important function in wi-fi earbuds. Samsung raised the bar by creating its personal Adaptive ANC expertise. The Galaxy Buds3 sequence adapts to the becoming circumstances of various customers and adjustments in match attributable to 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,” stated Kyoungbo Min. “By means of in depth simulations, we ready an answer that could possibly be rapidly 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 area. With Audio Eraser making full use of sound supply separation, the corporate is getting ready to broaden into a variety of latest 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 kinds of sound could be detected corresponding 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 will not be assured.
