Claim 7:
8. An apparatus for generating a modified sound field description, comprising:
an interface configured for receiving a first sound field description related to a first reference location and for receiving a second sound field description related to a further reference location being different from the first reference location; and
a sound field calculator configured for calculating the modified sound field description using a translation information indicating a translation of the first reference location or the further reference location to a different reference location, wherein the sound field calculator is configured:
to match a first group of sources of the first sound field description and a second group of sources of the second sound field description to obtain one or more matched sources,
to determine a direction of arrival information for each matched source of the one or more matched sources,
to determine a distance of a source to the different reference location using the direction of arrival information and meta data for the first sound field description or the second sound field description, and
to determine a scaling factor using the distance of the source to the different reference location.
