Abstract: Method, equipment and apparatus for acquiring a spatial audio direction vector, the method including: determining a position of a sound source in a multi-sound system; setting a parameter comprising: a human response time ?t and a tolerance percentage ?; acquiring a sound signal from the sound source; and processing the sound signal by using the parameter and acquiring a corresponding spatial audio direction vector {right arrow over (E)} within each time interval ?t. A proportional constant D is determined according to a modulus of a spatial audio direction vector {right arrow over (E)}, and provides spatial information of depth for a virtual image corresponding to a multi-tone audio signal. A vector angle ?E the spatial audio direction vector {right arrow over (E)} provides spatial information of direction for the virtual image corresponding to the multi-tone audio signal, to improve viewer's viewing experience.
