Abstract:
An apparatus for generating an enhanced sound field description has: a sound field generator for generating at least two sound field layer descriptions indicating sound fields with respect to at least one reference location; and a meta data generator for generating meta data relating to spatial information of the sound fields, wherein the sound field descriptions and the meta data constitute the enhanced sound field description. The meta data can be a geometrical information for each layer such as a representative distance to the reference location.
