Abstract
An audio system having a depth capturing device and a microphone array to respectively detect a point cloud and a local sound field, is described. The point cloud includes points corresponding to objects in a source space, and the local sound field includes sounds received in respective directions from the source space. The audio system includes one or more processors to generate a global sound field based on distances to the points and directions of the sounds. The global sound field includes virtual sound sources emitting respective sounds at respective points. A speaker can render the virtual sound sources to a user in a virtual space that corresponds to the source space.
