Detailed Description

struct vx_req_session_set_3d_position;
Set and get the 3D position of the speaker and listener.
See: vx_req_session_set_3d_position
For most applications, it is expected that the speaker and listener positions are the same. The SDK also supports the decoupling of these positions (for example, for the implementation of a camera audio zoom, the virtual "mouth" is where the avatar is, and the virtual "ears" are where the camera view is).
