    Abstract: Audio perception in local proximity to visual cues is provided. A device includes a video display, first row of audio transducers, and second row of audio transducers. The first and second rows can be vertically disposed above and below the video display. An audio transducer of the first row and an audio transducer of the second row form a column to produce, in concert, an audible signal. The perceived emanation of the audible signal is from a plane of the video display (e.g., a location of a visual cue) by weighing outputs of the audio transducers of the column In certain embodiments, the audio transducers are spaced farther apart at a periphery for increased fidelity in a center portion of the plane and less fidelity at the periphery.

    Abstract: Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. The object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content.

    Abstract: A method of rendering an audio program by generating one or more loudspeaker channel feeds based on the dynamic trajectory of each audio object in the audio program, wherein the parameters of the dynamic trajectory may be included explicitly in the audio program, or may be derived from the instantaneous location of audio objects at two or more points in time. Embodiments include rendering audio by defining a nominal loudspeaker map of loudspeakers used for playback of the audio program, determining a trajectory of an auditory source corresponding to one or more audio objects through 3D space, generating loudspeaker signals feeding the loudspeakers based on the one or more audio object trajectories, and rendering the one or more audio objects based on object location to match the trajectory of the auditory source as perceived by a listener.
