Binauralization of rotated higher order ambisonics

摘要

A device comprising one or more processors is configured to obtain transformation information, the transformation information describing how a sound field was transformed to reduce a number of a plurality of hierarchical elements to a reduced plurality of hierarchical elements; and perform binaural audio rendering with respect to the reduced plurality of hierarchical elements based on the transformation information.

1. A method of binaural audio rendering comprising:
obtaining a bitstream that includes encoded audio data and transformation information; decoding the encoded audio data to obtain a reduced plurality of hierarchical elements, the transformation information describing how a sound field represented by a plurality of hierarchical elements was transformed in order to generate the reduced plurality of hierarchical elements, the reduced plurality of hierarchical elements having a number of hierarchical elements that is less than a number of the plurality of hierarchical elements; and performing the binaural audio rendering with respect to the reduced plurality of hierarchical elements based on the transformation information.
