Claim:
1. A method comprising: performing, by and audio encoding device, a decomposition with respect to a plurality of spherical harmonic coefficients representative of a sound field to generate a U matrix representative of left-singular vectors of the plurality of spherical harmonic coefficients, an S matrix representative of singular values of the plurality of spherical harmonic coefficients and a V matrix representative of right-singular vectors of the plurality of spherical harmonic coefficients; determining, by the audio encoding device, one or more U determining, by the audio encoding device, one or more S determining, by the audio encoding device, one or more V quantizing, by an audio encoding device, the one or more V compensating, by the audio encoding device, for error introduced due to the quantization of the one or more V audio encoding, by the audio encoding device, the one or more error compensated U generating, by the audio encoding device, a bitstream to include the audio encoded one or more error compensated U
