Abstract
The rapid development of 3D video inspired the demand for 3D audio technology and products, but the products on the market currently are difficult to produce a real 3D audio effect synchronized with 3D videos. This article derive generating principles and formulas for movable virtual sound source base on VBAP and Clustering in the 3D sound field, design and implement the method to generate 3D Audio Content, the produced virtual sound source could customize different trajectories and speed in the 3D sound field. As to different 3D audio systems, after modify the corresponding parameters according to the allocation model, could generate suitable 3D audio and make audiences feel ubiquitous audio-visual enjoyment. After field tests in the 3D sound field, the movement of the movable virtual sound source generated by this method is obvious and stable, vastly improves the efficiency and accuracy compared with manual method, provide a high efficiency generating method for related film creation.
