Claim 0:
1. 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 source separation to the first sound field description to obtain a first group of one or more extracted objects and the second sound field description to obtain a second group of one or more extracted objects,
to match the first group of extracted objects of the first sound field description and the second group of extracted objects of the second sound field description to obtain one or more matched objects, wherein one or more extracted objects that are different from the one or more matched objects are one or more non-matched objects,
to estimate a position of a matched object of the one or more matched objects, and
to modify the matched object of the one or more matched objects based on the estimated position of the matched object of the one or more matched objects and the different reference location.
