In this article, we’ll delve into the world of HDMI cables, Dolby Atmos, and explore the answer to this question.
What is Dolby Atmos?
Before we dive into the world of HDMI cables, it’s essential to understand what Dolby Atmos is and how it works. Dolby Atmos is an immersive audio technology that allows for the creation and playback of 3D audio, where sound objects are precisely placed and moved in three-dimensional space. This technology is designed to recreate the way sound behaves in the real world, creating a more realistic and engaging audio experience.
In a Dolby Atmos system, speakers are arranged in a specific configuration to create a 3D sound field. This configuration typically includes overhead speakers, which are used to create the sense of height and immersion. The audio signal is then processed to accurately place sound objects in three-dimensional space, creating a truly immersive experience.
