Embodiment Construction

[0030] The following detailed description, with reference to and with the drawings, describes and illustrates one or more specific examples of audio processing techniques. These techniques have been shown and described in sufficient detail, not to be limiting, but merely to illustrate and teach the disclosure, to enable any person skilled in the art to practice the disclosed technique. Accordingly, where appropriate to avoid obscuring the technology, the description may omit certain information known to those of ordinary skill in the art.

[0031] The word "exemplary" is used throughout this application to mean "serving as an example, instance, or illustration." Any system, method, device, technique, feature, or the like described herein as "exemplary" should not necessarily be construed as preferred or advantageous over other features.

[0032] An advantage of the audio processing techniques disclosed herein is that audio capture can be customized via a graphical user interf...

Abstract

Techniques for processing directionally-encoded audio to account for spatial characteristics of a listener playback environment are disclosed. The directionally-encoded audio data includes spatial information indicative of one or more directions of sound sources in an audio scene. The audio data is modified based on input data identifying the spatial characteristics of the playback environment. The spatial characteristics may correspond to actual loudspeaker locations in the playback environment. The directionally-encoded audio may also be processed to permit focusing / defocusing on sound sources or particular directions in an audio scene. The disclosed techniques may allow a recorded audio scene to be more accurately reproduced at playback time, regardless of the output loudspeaker setup. Another advantage is that a user may dynamically configure audio data so that it better conforms to the user's particular loudspeaker layouts and / or the user's desired focus on particular subjects or areas in an audio scene.

Description

[0001] priority claim [0002] This patent application asserts Provisional Application No. 62 / 099,395, filed January 2, 2015, and U.S. Application Serial No. 14 / 807,760, filed July 23, 2015 (both titled "Having User-Configurable Multi-Channel Sound Reproduction With User Configurable SoundFocus"), and is hereby expressly incorporated by reference in its entirety as if fully set forth herein. technical field [0003] The present invention relates generally to audio systems, and, more particularly, to a dynamically configurable multi-channel audio system. Background technique [0004] Conventional multi-channel recording typically assumes fixed loudspeaker positions in the playback environment; and thus, some conventional multi-channel sound systems process and store audio signals based on standard loudspeaker configurations. The standard multi-channel loudspeaker configuration includes conventional L-R stereo, 5.1 surround sound and 7.1 surround sound and other speakers. H...
