Abstract

An audio format transcoder for transcoding an input audio signal, the input audio signal having at least two directional audio components. The audio format transcoder including a converter for converting the input audio signal into a converted signal, the converted signal having a converted signal representation and a converted signal direction of arrival. The audio format transcoder further includes a position provider for providing at least two spatial positions of at least two spatial audio sources and a processor for processing the converted signal representation based on the at least two spatial positions to obtain at least two separated audio source measures.
