Which format is a common example of immersive audio with height channels?

• A. Dolby Atmos.
• B. Dolby Digital 5.1.
• C. Stereo.
• D. Mono.

Answer: (A)

Immersive audio with height channels adds a vertical dimension to sound, not just left-right placement. Dolby Atmos is designed for this by using height information and object-based audio, so sounds can originate from above the listener as well as around them. It achieves this with ceiling speakers or up-firing modules and through metadata that lets each sound object be positioned in 3D space and moved as the scene plays. Other formats like Dolby Digital 5.1 provide traditional horizontal surround with fixed channels and don’t convey height information, while stereo and mono are two-channel or single-channel formats without any vertical placement. That combination of 3D positioning and height channels makes Atmos the standard example of immersive audio with height."
