Claim 5:
6. 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 on the first sound field description and on the second sound field description to obtain extracted sources of the first sound field description and the second sound field description,
to obtain direction of arrival (DoA) data for the extracted sources,
to calculate, for each extracted source of the extracted sources, modified DoA data with respect to the different reference location using the DoA data and the translation information, and
to process the extracted sources and the modified DoA data to obtain the modified sound field description.
