Abstract
First video frames that include a visual object and a non-spatialized first audio segment that includes an auditory event are received. If that second video frames do not include the visual object and a first time difference between the first video frames and the second video frames does not exceed a certain time, a motion vector of the visual object is used to assign a spatial location to the auditory event in at least one of the second video frames. A second audio segment that includes the auditory event and third video frames are received. If the third video frames do not include the visual object and a second time difference between the first video frames and the third video frames exceeds the certain time, the auditory event is assigned to a diffuse sound field. An audio output that conveys spatial locations of the visual object is output.
