System for rendering and playback of object based audio in various listening environments
First Claim
1. A system for playback of spatial audio-based sound using reflected sound elements, comprising:
- a network linking components of the system in a listening environment;
an array of individually addressable audio drivers for distribution around the listening environment, wherein each driver is associated with a unique identifier defined within a communication protocol of the network,and wherein a first portion of the array comprise drivers configured to transmit sound directly to a location in the listening environment,and wherein a second portion of the array comprise drivers configured to transmit sound to the location after reflection off of one or more surfaces of the listening environment, wherein at least one driver of the second portion is an upward-firing driver configured to project sound waves toward a ceiling of the listening environment for reflection down to said location, in such a manner as to simulate the presence of at least one height speaker positioned in the ceiling, anda renderer coupled to the array of drivers and configured to route audio streams of the spatial audio-based sound to either the first portion of the array or the second portion of the array based on one or more characteristics of the audio streams and the listening environment, characterized in that the system further comprises,a height cue filter for generating perceptual height cues for audio objects in the reflected audio streams, the perceptual height cues derived by at least partially removing from the reflected audio streams a first height cue for a physical speaker location in the listening environment and at least partially inserting in the reflected audio streams a second height cue for a reflected speaker location.

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.
