    摘要： Embodiments are directed a method of rendering object-based audio comprising determining an initial spatial position of objects having object audio data and associated metadata, determining a perceptual importance of the objects, and grouping the audio objects into a number of clusters based on the determined perceptual importance of the objects, such that a spatial error caused by moving an object from an initial spatial position to a second spatial position in a cluster is minimized for objects with a relatively high perceptual importance. The perceptual importance is based at least in part by a partial loudness of an object and content semantics of the object.

    摘要： Methods, apparatuses and program logic in storage media to process media data for quality enhancement. The media data is for rendering at a wireless device. Environmental quantities are accepted from one or more sensors located remote from the wireless device but sufficiently close to be indicative of similar quantities in the device's environment. The sensors at in or connected to a network node. At the network node, the method includes processing the media data using the environmental quantities to generate processed data, and wirelessly sending the processed output to the resource constrained device for rendering, such that the processed output is usable by the resource constrained device to render or to process and render the media data.

    摘要： Embodiments are directed to upward-firing speakers that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The upward firing driver is tilted at an inclination angle of approximately 20 degrees to the horizontal axis of the speaker and separate height and direct terminal connections are provided to interface to an adaptive audio rendering system.

    摘要： At least part of a speaker calibration process, such as a process of adjusting the gain of a top-firing speaker of a virtual height speaker system to compensate for ceiling height and/or ceiling acoustic reflectivity, may be done using a mobile device (a smart phone, a tablet, etc.) running a mobile device application on a mobile operating system (iOS, Android, etc.). An un-calibrated or minimally calibrated microphone, of the type typically found in mobile devices such as smart phones and tablets, may be used to provide input for such speaker calibration processes.
