Has Samsung and Google behind it, will be open source.
Samsung and Google are ready to push a new standard, Eclipsa Audio. This format will enable 3D audio experiences on certain YouTube videos later this year, with support available across Samsung’s 2025 lineup of TVs and soundbars. Over the years, Samsung notably hasn’t supported Dolby Vision HDR for dynamic HDR metadata, choosing instead to promote its preferred alternative, HDR10 Plus. Now, it seems ready to make a similar competitive push for open-source 3D audio support.
Eclipsa Audio could eventually serve as a free alternative to Dolby Atmos, the dominant 3D audio format that hardware makers like Samsung pay to license for TVs and other equipment. Samsung says that similar to Atmos, this audio format supports adjusting “audio data such as the location and intensity of sounds, along with spatial reflections” to create a 3D experience.
