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: 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: Embodiments are directed to an interconnect for coupling components in an object-based rendering system comprising: a first network channel coupling a renderer to an array of individually addressable drivers projecting sound in a listening environment and transmitting audio signals and control data from the renderer to the array, and a second network channel coupling a microphone placed in the listening environment to a calibration component of the renderer and transmitting calibration control signals for acoustic information generated by the microphone to the calibration component. The interconnect is suitable for use in a system for rendering spatial audio content comprising channel-based and object-based audio components.

Abstract: Embodiments are described for a synchronization and switchover mechanism for an adaptive audio system in which multi-channel (e.g., surround sound) audio is provided along with object-based adaptive audio content. A synchronization signal is embedded in the multi-channel audio stream and contains a track identifier and frame count for the adaptive audio stream to play out. The track identifier and frame count of a received adaptive audio frame is compared to the track identifier and frame count contained in the synchronization signal. If either the track identifier or frame count does not match the synchronization signal, a switchover process fades out the adaptive audio track and fades in the multi-channel audio track. The system plays the multi-channel audio track until the synchronization signal track identifier and frame count and adaptive audio track identifier and frame count match, at which point the adaptive audio content will be faded back in.
