More Sound with HDMI Technology

The best way to get maximum audio quality is with wired connectivity rather than wireless. HDMI® Technology features Enhanced Audio Return Channel (eARC) and delivers the highest performing audio for elaborate home theater set-ups via audio-video receivers and multiple speaker systems, or simple eARC-enabled soundbars.

One of the biggest benefits of using eARC is its support for high bit rate, object-oriented formats that bring audio to life in your living room. eARC supports formats with up to 192kHz sampling rate and 24-bit depth, and a maximum audio bandwidth of 37 Mbits/second, letting you hear every nuance — from the delicate rustle of leaves to the powerful impact of cinematic explosions. For sports, eARC delivers crystal-clear commentary alongside the roar of the crowd, and for gaming, it allows for precise, immersive sound that puts you at the heart of the action.

HDMI eARC also enables cutting-edge audio formats like Dolby Atmos and DTS:X. These immersive sound technologies use height and directional audio cues to create a three-dimensional soundstage, making you feel as if you’re inside the movie, game, or stadium. Whether you opt for a full home theater system or a compact soundbar, eARC ensures these formats are delivered with maximum fidelity.

To fully experience eARC’s capabilities, your cables matter. Premium High Speed HDMI® Cables are suitable for supporting system configurations up to 18Gbps, while Ultra High Speed HDMI® Cables support configurations higher than 18Gbps, up to 48Gbps. Either cable can provide the best audio performance, so end users should choose a cable that best supports the video capabilities of their system. Both the Premium High Speed and Ultra High Speed HDMI Cables require the official HDMI Certification Labels to be displayed on packaging. To find out more, visit www.hdmi.org.

It is also important to note that not only HDTV and home theater can be enhanced with HDMI eARC sound applications, but music is also supported. Higher bitrate audio applications such as Dolby Atmos are provided in most major music streaming services, and having the right system to deliver the best performance can make stereo soundstage and depth feel like being in a live performance.

HDMI eARC technology offers unmatched audio performance by supporting the highest quality formats and immersive sound experiences. Paired with the right certified HDMI Cables, it unlocks the full potential of movies, sports, gaming, and even music. For both consumers and retailers, investing in eARC-enabled sound solutions and certified cables ensures an optimal, future-ready home entertainment setup.
