Claim 15:
16. The non-transitory computer-readable storage medium of claim 13, wherein the computer instructions, when executed by the one or more processors of the system, further cause the system to:
obtain M third positions of the M first virtual speakers relative to a current head center, wherein each of the M third positions comprises a first azimuth and a first elevation of a first virtual speaker relative to the current head center, and wherein each of the M third positions further comprises a first distance between the current head center and the first virtual speaker;
determine M fourth positions based on the M third positions, wherein the M third positions are in a one-to-one correspondence with the M fourth positions, wherein each of the M fourth positions and a corresponding M third position comprise a same elevation and a same distance, wherein a difference between an azimuth in each of the M fourth positions and a first value is a first azimuth in the corresponding M third position, wherein the first value is a difference between a first included angle and a second included angle, wherein the first included angle is between a first straight line and a first plane, wherein the second included angle is between a second straight line and the first plane, wherein the first straight line passes through a current left ear position and a coordinate origin of a three-dimensional coordinate system, wherein the second straight line passes through the current head center and the coordinate origin, and wherein the first plane is defined by an X axis and a Z axis of the three-dimensional coordinate system; and
determine, based on the M fourth positions and correspondences between a plurality of preset positions and a plurality of HRTFs, that the M first HRTFs correspond to the M fourth positions.
