Patent ID: 8891797

Claim:
An audio format transcoder for transcoding an input audio signal, the input audio signal comprising at least two directional audio components, comprising: a converter configured for converting the input audio signal into a converted signal, the converted signal comprising a converted signal representation and a converted signal direction of arrival; a position provider configured for providing at least two spatial positions of at least two spatial audio sources; and a processor configured for processing the converted signal representation based on the at least two spatial positions and the converted signal direction of arrival to acquire at least two separated audio source measures, wherein the processor is adapted for determining a weighting factor for each of the at least two separated audio sources, and wherein the processor is adapted for processing the converted signal representation in terms of at least two spatial filters depending on the weighting factors for approximating at least two isolated audio sources with at least two separated audio source signals as the at least two separated audio source measures, or wherein the processor is adapted for estimating a power information for each of the at least two separated audio sources depending on the weighting factors as the at least two separated audio source measures.
