At CES 2025, a groundbreaking announcement was made that could potentially reshape the landscape of immersive audio. Google and Samsung unveiled Eclipsa Audio, an open-source 3D audio format that many believe could give Dolby Atmos a run for its money. With its debut slated for Samsung’s 2025 smart TV lineup, Eclipsa Audio promises to democratize high-fidelity spatial sound—and its implications reach far beyond the TV screen.

For decades, spatial audio technologies have been confined mostly to high-end cinemas and professional studios. In a revealing blog post earlier this year, Google explained, “Spatial audio technologies were first developed over 50 years ago, and playback has been available to consumers for over a decade, but creating spatial audio has been mostly limited to professionals in the movie or music industries.” This sentiment set the stage for Eclipsa Audio—a format designed to open up 3D sound creation to everyone, from independent filmmakers to home video enthusiasts.

Unlike Dolby Atmos, which is a proprietary system, Eclipsa Audio is built on an open-source model. This means that its tools and technologies are accessible to a broader range of creators, fostering innovation and potentially leading to a surge in high-quality immersive content. By leveraging the Immersive Audio Mode and Formats (IAMF), Eclipsa Audio precisely positions sounds in a virtual space, creating an enveloping auditory experience that feels as if the sound is coming from all directions.

At its core, Eclipsa Audio is a channel-based 3D audio format. The integration of IAMF ensures that every nuance of the soundscape is captured and delivered with impressive accuracy. This not only enhances the overall viewing experience but also offers content creators a new canvas on which to experiment with audio storytelling. Imagine watching your favorite action movie or live concert, where every explosion, note, or whispered dialogue is rendered with lifelike precision, transforming your living room into a personal theater.

The collaborative effort behind Eclipsa Audio isn’t limited to just Google and Samsung. It’s a project supported by the Alliance for Open Media (AOM), which brings together industry leaders committed to fostering open standards in media technology. This collaboration bodes well for the future adoption and development of the format.

Initially, Eclipsa Audio will make its presence felt on Android devices, thanks to its integration with the upcoming Android 16 operating system. This means that any smart TV powered by Android—think Google TVs, as well as models from Hisense, Sony, and more—will soon support this immersive format. Adding to the excitement, FlatpanelsHD has reported that LG’s webOS will also eventually roll out support for Eclipsa, though the timeline remains somewhat murky.

Perhaps the most immediate impact will be on the digital content front. Google-owned YouTube is set to be one of the first platforms to embrace Eclipsa Audio. Later this year, YouTube creators will have the opportunity to upload videos enhanced with 3D audio, giving millions of users a taste of a truly immersive auditory experience.

While the buzz around Eclipsa Audio is undeniably positive, its long-term success hinges on broader industry adoption. Streaming giants like Netflix and tech behemoths such as Apple (with their tvOS and iOS platforms) have yet to announce support for the new format. This gap raises important questions: Will filmmakers, streaming services, and audio engineers make the switch? And how quickly will Eclipsa Audio gain traction among the vast ecosystem of digital media?

The answer may well depend on the format’s accessibility and the quality of the content produced. As more creators experiment with Eclipsa Audio and its capabilities, audiences might begin to see a shift in how spatial audio is perceived—moving from a niche feature to a standard expectation in home entertainment.

Eclipsa Audio represents more than just a technical upgrade—it’s a paradigm shift in how we experience sound. By removing the barriers to entry for high-quality spatial audio creation, Google and Samsung are not only challenging established norms but are also inviting a new generation of innovators to explore the full potential of 3D sound.

For the casual movie-goer, the dedicated audiophile, and everyone in between, the promise of a richer, more immersive listening experience is an exciting prospect. As the format expands across devices and platforms, it will be fascinating to watch how this open-source initiative reshapes our audio landscape.
