Problems solved by technology

[0006] As the number of channels increases and loudspeaker layouts change from flat two-dimensional (2D) arrays to three-dimensional (3D) arrays that include heights, the task of localizing and presenting sounds becomes increasingly difficult

Embodiment Construction

[0065] The following description is directed to specific implementations for purposes of describing some of the innovative aspects of the disclosure, as well as examples of contexts in which these innovative aspects can be implemented. However, the teachings herein can be applied in a variety of different ways. For example, although various implementations are described in terms of a particular rendering environment, the teachings herein are broadly applicable to other known rendering environments, as well as rendering environments that may be introduced in the future. Similarly, while graphical user interface (GUI) examples are given herein, some of which provide examples of speaker locations, speaker zones, etc., other implementations are also contemplated by the inventors. Moreover, the described implementations can be implemented in various authoring and / or presentation tools that can be implemented in various hardware, software, firmware, etc. Accordingly, the teachings ...

Abstract

Provides improved tools for authoring and presenting audio reproduction data. Some of these authoring tools allow audio reproduction data to be generalized for use in a variety of reproduction environments. Audio reproduction data can be authored by creating metadata on an audio object. The metadata may be created with reference to speaker zones. During the rendering process, audio reproduction data may be reproduced according to a reproduction speaker layout of a particular reproduction environment.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 61 / 504,005, filed July 1, 2011, and U.S. Provisional Application No. 61 / 636,102, filed April 20, 2012, both of which are published in their entirety Incorporated by reference for all purposes. technical field [0003] The present disclosure relates to the authoring and presentation of audio reproduction data. In particular, the present disclosure relates to authoring and rendering audio reproduction data for reproduction environments such as theater sound reproduction systems. Background technique [0004] Since the introduction of sound with film in 1927, the technology used to capture the artistic intent of a film soundtrack and reproduce it in a theater environment has evolved steadily. In the 1930s, synchronized sound on disc gave way to variable volume sound on film, which was developed in the 1940s through theater acoustic considerations and i...
