3D Spatial Audio delivers a fully immersive soundscape that is responsive to a visual field. When you move your head in one direction or another, the audio changes to reflect that movement.
Unlike stereo audio, the sound is locked in space rather than to your head. This allows you to move around the room and the sound will remain locked spatially to your surroundings. In order to generate spatial audio, you must be able to combine audio with coordinate data that will alert the system to perceive subtle head movements.
