Claim 16:
17. 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 perform a sound analysis to the first sound field description to obtain a first group of one or more extracted objects or a direction of arrival information for one or more extracted objects and to the second sound field description related to the further reference location to obtain a second group of one or more extracted objects or a direction of arrival information for one or more extracted objects using meta data for the first sound field description or the second sound field description;
to match the first group and the second group using object signals from the groups or direction of arrival information for objects from the groups to find at least one matched object, and
to calculate a sound field description for each non-matched object from the first group using the direction of arrival information for the corresponding non-matched object from the first group and to calculate a sound field description for each non-matched object from the second group using the direction of arrival information for the corresponding non-matched object from the second group.
