Samsung Electronics recently unveiled one of its boldest audio propositions for 2025: the integration of **Eclipsa Audio**, a revolutionary three-dimensional sound technology developed in collaboration with Google, into its TV and soundbar lineups.
Taeyong Son, Executive Vice President and R&D Team Leader for Visual Display Business at Samsung, said: “This innovation opens up new perspectives for immersive audio experiences and reinforces our commitment to shaping the future of home entertainment. He made the announcement during a presentation at CES 2025.
**Eclipsa Audio** could become a free alternative to Dolby Atmos, the prevailing 3D audio format for which hardware manufacturers have to pay licensing fees for their devices such as TVs. Samsung claims that, like Atmos, its audio format allows for adjustments to “data such as the location and intensity of sounds, as well as spatial reflections”, providing a three-dimensional experience.

This technology is designed to provide a three-dimensional audio experience through the manipulation of advanced audio data. It allows content creators to precisely define the placement and intensity of sounds as well as reflections to achieve an immersive sound environment that enhances the listener’s perception.
The new component is supposed to integrate harmoniously with Samsung TVs and guarantee faithful reproduction of content created in this format. This means a noticeable improvement in the way users experience sound, bringing a dimension of depth and realism.
Samsung has decided to include Eclipsa Audio in its entire line of TVs for 2025. Whether it is the Crystal UHD series or the high-end Neo QLED 8K models, users will be able to benefit from this innovation in many, many configurations.
Additionally, starting in 2025, content creators will be able to upload videos with Eclipse-compatible soundtracks to platforms such as YouTube. To ensure consistent, high-quality reproduction, Samsung and Google have partnered with the Telecommunications Technology Association (TT A) to create a certification program.

To make creating Eclipsa audio files easier, a free AVID Pro Tools digital audio workstation add-on will be launched in the first half of the year. In addition, by the end of 2025, support for surround sound will be implemented in the Google Chrome browser and on TVs and soundbars from various manufacturers.
Eclipse audio compatibility will also be integrated into the upcoming open source version of Android to expand its availability across multiple devices and platforms.
From creation to distribution and experience
Surround sound technologies have been around for over 50 years and their reproduction has been available to the general public for over a decade. However, creating surround sound remains primarily reserved for professionals in the film and music industries.
Eclipsa Audio is based on the **Immersive Audio Model and Formats** (IAMF), developed by Google, Samsung and others under the Alliance for Open Media (AOM) and released under a free license. Since it is open source, anyone can create Eclipse audio files using free audio tools supporting multiple workflows, including video and audio encoding with iamf_tools and FFmpeg to create MP4 files containing IAMF audio and video.
There is also an open source reference renderer for independent surround sound reproduction that allows users to test their Eclipsa audio files directly through the binaural online demo application.
The initiative by Samsung and Google raises interesting questions about the future development of immersive audio and its availability to more users. As this technology evolves, how will consumer demand for increasingly engaging audio experiences impact?
