CONCEPT POUR GÉNÉRER UNE DESCRIPTION DE CHAMP SONORE AMÉLIORÉE OU UNE DESCRIPTION DE CHAMP SONORE MODIFIÉE À L'AIDE D'UNE TECHNIQUE DE DIRAC ÉTENDUE EN PROFONDEUR OU D'AUTRES TECHNIQUES

摘要

An apparatus for generating an enhanced sound field description includes: a sound field generator for generating at least one sound field description indicating a sound field with respect to at least one reference location; and a meta data generator for generating meta data relating to spatial information of the sound field, wherein the at least one sound field description and the meta data constitute the enhanced sound field description. The meta data can be a depth map associating a distance information to a direction in a full band or a subband, i.e., a time frequency bin.
