Title:
SPECIFYING SPHERICAL HARMONIC AND/OR HIGHER ORDER AMBISONICS COEFFICIENTS IN BITSTREAMS
Document Type and Number:
WIPO Patent Application WO/2014/134462
Kind Code:
A3
Abstract:
In general, techniques are described for specifying spherical harmonic coefficients in a bitstream. A device comprising one or more processors may perform the techniques. The processors may be configured to identify, from the bitstream, a plurality of hierarchical elements describing a sound field that are included in the bitstream. The processors may further be configured to parse the bitstream to determine the identified plurality of hierarchical elements.
