It is possible to get Dolby Atmos audio through HDMI-ARC (Audio Return Channel). However, there are some limitations to be aware of.
Dolby Atmos is an immersive audio format that adds height and overhead sound to create a three-dimensional audio experience. It allows for more precise placement of sounds within a room, providing a more realistic and enveloping audio experience.
To transmit Dolby Atmos audio, the audio source (such as a Blu-ray player or streaming device) needs to support Dolby Atmos and be connected to an AV receiver or soundbar that is also capable of decoding and processing Dolby Atmos.
When it comes to connecting your AV receiver or soundbar to your TV, HDMI-ARC is a commonly used method. HDMI-ARC allows audio to be sent from the TV back to the AV receiver or soundbar, eliminating the need for a separate audio connection. This can help simplify the setup and reduce cable clutter.
In most cases, Dolby Atmos audio can be played through HDMI-ARC using the Dolby Digital Plus codec. Dolby Digital Plus is a compressed audio format that supports Dolby Atmos. It allows for the transmission of Dolby Atmos metadata within the audio stream, which can then be decoded and processed by the AV receiver or soundbar.
However, it’s important to note that HDMI-ARC has bandwidth limitations, which means it may not be able to transmit lossless Dolby Atmos audio using the Dolby TrueHD codec. Dolby TrueHD is an uncompressed audio format that provides the highest quality audio experience. To play lossless Dolby Atmos audio, HDMI-eARC (Enhanced Audio Return Channel) is required.
HDMI-eARC is an updated version of HDMI-ARC that offers higher bandwidth and can transmit lossless audio formats like Dolby TrueHD. It allows for the full quality and fidelity of Dolby Atmos to be preserved and delivered to your AV receiver or soundbar.
If your TV and AV receiver or soundbar support HDMI-eARC, you will be able to enjoy the full benefits of lossless Dolby Atmos audio. However, it’s worth noting that not all TVs and AV receivers or soundbars are equipped with HDMI-eARC, so you’ll need to check the specifications of your devices to ensure compatibility.
While it is possible to get Dolby Atmos audio through HDMI-ARC, there are limitations in terms of the audio codec and quality. Most Dolby Atmos audio can be played through HDMI-ARC using the Dolby Digital Plus codec, but for lossless Dolby Atmos audio using the Dolby TrueHD codec, HDMI-eARC is required. It’s important to check the specifications of your devices to ensure compatibility and enjoy the best possible audio experience.
