Original Abstract Submitted
an apparatus for estimating sub-band-specific direction information for two or more sub-bands of a plurality of sub-bands according to an embodiment is provided. the apparatus has a feature extractor for obtaining a plurality of feature samples for a plurality of frequency bands of two or more audio signals. moreover, the apparatus has a direction estimator being configured to receive the plurality of feature samples as input values and being configured to output a plurality of output samples wherein the output samples indicate, for each sub-band of the two or more sub-bands, the sub-band-specific direction information for said sub-band. each of the plurality of sub-bands is equal to one of the plurality of frequency bands or has at least one frequency band or a portion of a frequency band of the plurality of frequency bands.
