Concept for generating augmented sound field descriptions or modified sound field descriptions using multi-point sound field descriptions

摘要

An apparatus for generating an augmented sound field description, comprising: a sound field generator (100, 250, 260) for generating at least one sound field description representing a sound field for at least one reference position; And a metadata generator 110 for generating metadata related to spatial information of the sound field, and constitutes a sound field description in which at least one sound field description and metadata are enhanced. The at least one sound field description includes, in certain cases, a first sound field description associated with the at least one reference location and a second sound field description associated with an additional reference location different from the reference location, and metadata related to spatial information includes the reference location and It represents either an additional reference position or a vector extending between the reference position and both reference positions.
