LG Embraces Samsung’s Eclipsa Audio to Challenge Dolby Atmos
LG is expanding its audio support to include Eclipsa Audio, a spatial audio format developed by Samsung and Google, as a direct competitor to Dolby Atmos. The move marks a notable shift for LG, which has historically been cautious about adopting rival technologies, and signals a growing challenge to Dolby’s dominance in the immersive audio market.
Eclipsa Audio Rollout: 2026 Models and Beyond
All of LG’s 2026 television models will support Eclipsa Audio. Select 2025 models are receiving the format via a free software update, including the LG G5, LG C5, LG CS5, and LG QNED9M series . The update, version 33.30.80 or newer, enables Eclipsa Audio playback through both the TVs’ built-in speakers and compatible soundbars, such as the Samsung HW-Q990F .
A Royalty-Free Alternative
Eclipsa Audio, technically known as IAMF, is being released by the Alliance for Open Media. A key differentiator from Dolby Atmos is its royalty-free structure, eliminating licensing fees for manufacturers . This allows companies to adopt the technology based purely on technical merit.
Samsung and Google’s Vision for Spatial Audio
Samsung developed Eclipsa Audio with the goal of expanding access to immersive audio, particularly for content creators who may discover the costs associated with Dolby Atmos prohibitive. Samsung Audio Lab VP Allan Devantier noted that Dolby’s presence in gaming and in-car audio is limited, creating opportunities for Eclipsa Audio to gain traction . Google has already integrated the technology into YouTube, aiming to broaden the availability of spatial audio across various services.
Why the Shift for LG?
LG has historically been selective in its adoption of competing formats, notably resisting support for HDR10+ despite its growing prevalence. Yet, the increasing popularity of YouTube, where Eclipsa Audio is already available, appears to be a key factor in LG’s decision. With Samsung and Google TV also supporting Eclipsa Audio, LG’s inclusion ensures compatibility with a growing ecosystem and prevents its platform from being left behind in delivering the best possible audio experience from popular streaming apps .
Future Integration and Expansion
Eclipsa Audio is set to be integrated into Android 16, with Google initially focusing on TV, soundbar, and interface support. The format is also planned for Google Chromecast devices and AV receivers . Samsung is reportedly working with Netflix and Amazon to explore the use of Eclipsa Audio for movies and TV shows, though no formal announcements have been made .
LG’s embrace of Eclipsa Audio represents a significant development in the spatial audio landscape, offering consumers more choice and potentially driving innovation in immersive sound experiences.
