Chapter 7
Height Channels
Listeners in real spaces are immersed in acoustic information that arrives from all directions. Capturing and reproducing the vertical aspect of an acoustic environment is essential for the complete rendering of immersive audio. To deliver periphonic information, several multichannel sound capture and reproduction systems have been developed that include dedicated height channels. By providing vertically oriented sound images, systems with height channels deliver a more convincing, natural, and immersive three-dimensional (3D) sound environment. This chapter will introduce loudspeaker configurations, microphone techniques, and the perceptual characteristics that are associated with height channels.
