Abstract: Embodiments are described for rendering spatial audio content through a system that is configured to reflect audio off of one or more surfaces of a listening environment. The system includes an array of audio drivers distributed around a room, wherein at least one driver of the array of drivers is configured to project sound waves toward one or more surfaces of the listening environment for reflection to a listening area within the listening environment and a renderer configured to receive and process audio streams and one or more metadata sets that are associated with each of the audio streams and that specify a playback location in the listening environment.

Abstract: A method for estimating an audio device location in an environment may involve obtaining direction of arrival (DOA) data for each audio device of a plurality of audio devices in the environment and determining interior angles for each of a plurality of triangles based on the DOA data. Each triangle may have vertices that correspond with audio device locations. The method may involve determining a side length for each side of each of the triangles, performing a forward alignment process of aligning each of the plurality of triangles produce a forward alignment matrix and performing a reverse alignment process of aligning each of the plurality of triangles in a reverse sequence to produce a reverse alignment matrix. A final estimate of each audio device location may be based, at least in part, on values of the forward alignment matrix and values of the reverse alignment matrix.

Abstract: Embodiments are described for a system of rendering object-based audio content through a system that includes individually addressable drivers, including at least one driver that is configured to project sound waves toward one or more surfaces within a listening environment for reflection to a listening area within the listening environment; a renderer configured to receive and process audio streams and one or more metadata sets associated with each of the audio streams and specifying a playback location of a respective audio stream; and a playback system coupled to the renderer and configured to render the audio streams to a plurality of audio feeds corresponding to the array of audio drivers in accordance with the one or more metadata sets.

Abstract: Volume leveler controller and controlling method are disclosed. In one embodiment, A volume leveler controller includes an audio content classifier for identifying the content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner based on the content type as identified. The adjusting unit may configured to positively correlate the dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.
