FIELD: electrical communication engineering.
SUBSTANCE: invention relates to means for compressing decomposed representations of a sound field. Bit stream is obtained containing a compressed version of the spatial component of the sound field. Spatial component is given in the region of spherical harmonics and is generated by performing the expansion with respect to the set of coefficients of the spherical harmonics, wherein the compressed version of the spatial component is represented in the bit stream using at least in part the field indicating the prediction mode used when compressing the spatial component.
EFFECT: technical result is improved efficiency of sound field processing.
