apparatus to generate a description of the sound field, computer program, improved description of the sound field and its method of generation

摘要

it is an apparatus for generating an enhanced sound field description comprising: a sound field generator (100, 250, 260) for generating at least one sound field description that indicates a sound field in relation to at least one location of reference; and a metadata generator (110) for generating metadata related to spatial sound field information, in which at least one description of the sound field and the metadata constitute the enhanced sound field description. the at least one description of the sound field comprises in a certain case a first description of the sound field related to at least one reference site and a second description of the sound field related to an additional reference site other than the reference site, and metadata related to spatial information indicate the reference location and the additional reference location or one of both reference locations and a vector that extends between both reference locations.
