An audio format transcoder (100) for transcoding an input audio signal, the input audio signal having at least two directional audio components. The audio format transcoder (100) comprising a converter (110) 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 (100) further comprises a position provider (120) for providing at least two spatial positions of at least two spatial audio sources and a processor (130) for processing the converted signal representation based on the at least two spatial positions to obtain at least two separated audio source measures.
La présente invention concerne un transcodeur de format audio (100) destiné à transcoder un signal audio d'entrée qui a au moins deux composantes audio directionnelles. Le transcodeur de format audio (100) comprend un convertisseur (110) permettant de convertir le signal audio d'entrée en un signal converti qui a une représentation et une direction d'arrivée de signal converti. Le transcodeur de format audio (100) comprend en outre un fournisseur de position, (120) destiné à fournir au moins deux positions spatiales d'au moins deux sources audio spatiales, et un processeur (130) destiné à traiter la représentation du signal converti sur la base des deux positions spatiales ou plus afin d'obtenir au moins deux mesures de sources audio distinctes.
