Abstract
Displaying visual information from a motion picture in a visual field within a designated extent of a related aural field supports editing of a spatial audio effect for the motion picture. The extent of a related aural field also is displayed. Information specifying a point of origin of a sound used in the spatial audio effect with respect to the visual field is received for each of a number of frames of a portion of the motion picture. This information may be received from a pointing device that indicates a point in the displayed extent of the aural field, or from a tracker that indicates a position of an object in the displayed visual information, or from a three-dimensional model of an object that indicates a position of an object in the displayed visual field. Using the specified point of origin and the relationship of the visual and aural fields, parameters of the spatial audio effect may be determined, from which a soundtrack may be generated. Information describing the specified point of origin may be stored. The frames for which points of origin are specified may be key frames that specify parameters of a function defining how the point of origin changes from frame to frame…
