I’m looking at cables for I2S and looking at Audioquest cables. They offer eARC and regular HDMI cables, and I can’t understand the difference between the two from reading materials on their website.
Can someone please let me know if I want the eARC or regular HDMI cable?
eARC stands for Enhanced Audio Return Channel, a feature of HDMI 2.1 that allows for higher quality audio transmission from a TV to a soundbar or AV receiver:
Improved bandwidth: eARC has a higher bandwidth than HDMI ARC, which allows for higher quality surround sound technologies.
Supports high-bitrate audio formats: eARC supports audio formats up to 192 kHz, 24-bit, and uncompressed 5.1 and 7.1.
Backward-compatible: eARC is backward-compatible with ARC.
Automatic processor delay correction: eARC can automatically correct processor delays to ensure audio and video match.
Lip sync correction: eARC can correct lip sync.
To get the best audio quality, all components in your system must be eARC-compatible. If any component is only ARC-compatible, your bandwidth may be limited by that device.
