Sony has introduced the HT-A5000 and HT-A3000 sound bars, which are equipped with its proprietary stereophonic technology 360 Spatial Sound Mapping.

"360 Spatial Sound Mapping" is a three-dimensional sound technique that combines a sound bar with dedicated rear speakers to create a large sound field and presence (sold separately). To comprehend the speakers' space, the built-in microphone automatically measures the distance between the sound bar and speakers, as well as to walls and ceilings. You can experience immersive sound by synthesizing the wavefront of sound from the sound bar and rear speakers, depending on that information. It also supports the innovative virtual surround technology "Vertical Surround Engine," and sound with a sensation of presence may be realized with a single bar speaker.
