Abstract  Abstract

PROBLEM TO BE SOLVED: To provide techniques for obtaining decomposed versions of spherical harmonic coefficients.

SOLUTION: An audio encoding device comprising one or more processors is configured to determine a first non-zero set of coefficients of a vector that represent a distinct component of a sound field. The vector has been decomposed from a plurality of spherical harmonic coefficients that describe the sound field.
