Embodiment Construction

[0056]The following description refers to some implementations for the purposes of describing some novel aspects of the disclosure and examples of backgrounds in which these novel aspects may be implemented. However, the teachings herein can be applied in a variety of different ways. For example, while various implementations are described in terms of a specific rendering environment, the teachings herein can be broadly applied to other known rendering environments as well as rendering environments that may be introduced in the future. Furthermore, the described implementations can be implemented in various authoring tools and / or rendering tools, which can be implemented in various hardware, software, firmware, etc. Accordingly, the teachings of this disclosure are not intended to be limited to the implementations shown in the figures and / or described herein, but have broad applicability.

Abstract

Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during "run time," during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Spanish Patent Application No. P201330461, filed March 28, 2013, and U.S. Provisional Patent Application No. 61 / 833,581, filed June 11, 2013, each of which The patent application is hereby incorporated by reference in its entirety. technical field [0003] This disclosure relates to authoring and rendering of audio reproduction data. In particular, the present disclosure relates to authoring and rendering audio reproduction data for a reproduction environment such as a theater sound reproduction system. Background technique [0004] Since the introduction of sound films in 1927, there has been a steady development of techniques for capturing the artistic intent of film soundtracks and reproducing them in a theater environment. In the 1930s, the synchronized sound of vinyl records was replaced by the variable area sound of film, using theater acoustic considerations and improved lou...
