摘要

it is an apparatus for generating an enhanced sound field description comprising: a sound field generator (100) for generating at least one sound field description that indicates a sound field with respect to at least one reference location; and a metadata generator (110) for generating metadata with respect to the spatial information of the sound field, with at least one sound field description and the metadata constituting the enhanced sound field description. metadata can be a depth map that associates distance information with a direction in a band or a subband, that is, a time and frequency compartment.
