Thee Science of Spatial Audio

Spatial audio recoves a three- dimensional sound field that simulates how human naturally locate sounds in their environmentat. The brain uses serel cues: interaural time differences (ITD), interaural level differences (ILD), spectral filtering by thee outer ear (pinnena), and subtle effects from head ande torso shados. Heade alone one non t provide these cues because thee sound source operates with thee listener; mprsquo; head.
