The at least one sound field description comprises in a certain case a first sound field description related to the at least one reference location and a second sound field description related to a further reference location being different from the reference location, and the meta data relating to the spatial infonnation indicates the reference location and the further reference location or one of both reference locations and a vector extending between both reference locations.
