Abstract  Abstract

PROBLEM TO BE SOLVED: To provide techniques for obtaining decomposed versions of spherical harmonic coefficients that are rendered to a 5.1 audio channel format or a 7.1 audio channel format accommodate backward compatibility and enable a better representation of a sound field.

SOLUTION: A device comprising one or more processors determines a first non-zero set of coefficients of a vector that represent a distinct component of a sound field. The vector is decomposed from a plurality of spherical harmonic coefficients that describe the sound field.
