LG TVs gain support for Eclipsa Audio

Support for Eclipsa Audio will roll out with LG's 2026 models, and the company is also bringing the new immersive audio format to select 2025 models via a firmware update.

Eclipsa Audio, also known as Immersive Audio Model and Formats (IAMF), is a royalty-free immersive audio format.

Developed by Google and Samsung, and released by the Alliance for Open Media, Eclipsa Audio is designed to compete with Dolby Atmos, much like HDR10+ offers an alternative to Dolby Vision HDR video.


Eclipsa Audio support in LG TVs
At its UK launch event in London, LG confirmed to FlatpanelsHD that it now officially supports Eclipsa Audio alongside Dolby Atmos.

Eclipsa Audio will be supported in all 2026 models, including the new OLED and 'micro RGB' LCD models. It works both for internal audio playback on the TV speakers (streaming, USB, etc.) and via HDMI output to a compatible audio system or soundbar.

FlatpanelsHD saw it in action using the LG G6's internal TV speakers, making it difficult to evaluate the audio experience. However, Eclipsa Audio worked as intended, with audio tracks identified as 'IAMF'.


Firmware update for 2025 models
Additionally, LG has started rolling out a firmware update for select 2025 models (C5, CS5, G5, QNED9M) to add support for Eclipsa Audio.

The firmware update is the same one that added Dolby Atmos FlexConnect, i.e. version 33.30.80 or later.


Eclipsa Audio in 2026
In early 2025, during a meeting with the Alliance for Open Media, FlatpanelsHD saw and heard Eclipsa Audio demonstrated, which you can read more about in this first look article.

At the time, the Alliance for Open Media hoped to bring it to LG TVs, Google TVs, Android, and more platforms, in addition to Samsung TVs, where it is already supported. Eclipsa Audio will arrive on Google TVs with Android 16.

Currently, only YouTube offers content in Eclipsa Audio, but the alliance aims to expand it to movies, series, games, music and other types of content across TVs, PCs, mobile devices and headsets.
