Embodiment Construction

[0049] Embodiments are described for audio speaker and transducer systems that include upward-firing drivers for rendering adaptive audio content intended to provide an immersive audio experience. Embodiments are also described for audio speakers that include upward-firing drivers with specially designed speaker trays that incorporate pinna filter functionality to render adaptive audio content intended to provide an immersive audio experience. Speakers may include or be used with an adaptive audio system with a virtual height filter for rendering object-based audio content using reflected sound to reproduce overhead sound objects and provide virtual height cues circuit. Aspects of one or more embodiments described herein may perform audio or audio-visual (AV) processing of source audio information in a mixing, rendering, and playback system that includes one or more computers or processing devices executing software instructions. ) system is implemented. Any of the described...

Abstract

Embodiments are directed to a virtual height filter for use with or in an upward-firing speaker system that reflects sound off a ceiling to a listening location at a distance from a speaker, and that 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 virtual height filter is provided by any one or combination of analog or digital filter circuits, or mechanical structures including speaker grill, enclosure, or driver design or configuration.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 007,354, filed June 3, 2014, and U.S. Provisional Patent Application No. 62 / 163,502, filed May 19, 2015, each of which is hereby Incorporated by reference thereto in its entirety. technical field [0003] One or more implementations relate generally to audio speakers, and more to up-firing speakers and active height filter circuits and passive speaker bracket configurations for providing virtual height filtering for up-firing speakers generating reflected signals. Background technique [0004] The advent of digital cinema has created new standards for cinema sound, such as the incorporation of multiple audio channels to allow greater creativity for content creators and a more enveloping and lifelike listening experience for listeners. As a means for distributing spatial audio content and rendering it in different playback configurations, mo...
