METHOD AND SYSTEM FOR SIMULATING SPATIAL SOUND IN AUGMENTED REALITY AND COMPUTER-READABLE STORAGE MEDIUM
A method for simulating spatial sound in augmented reality (AR) is disclosed. Multiple sound packets are emitted by a 4D object located on an anchor device in an AR scene. A distance, an angle and spatial relationship between the AR device and the anchor device are calculated. The sound packets are converted into 6DoF sound signals according to the calculated distance, the angle, the spatial relationship, an original sound source and user volume settings using a sound positioning algorithm. The 6DoF sound signals are sent to a playback device of the AR device.
