6dof rendering of microphone-array captured audio for locations outside the microphone-arrays

Abstract

An apparatus for generating a spatialized audio output based on a listener position, the apparatus including circuitry configured to: obtain two or more audio signal sets; obtain a listener position within an audio environment, wherein the audio environment includes one or more area having one or more inside and outside regions in relation to the respective audio signal set positions; obtain metadata based on a processing of the at least two audio signals; determine, for the listener position within an audio environment outside the inside region, a second listener position; determine modified metadata for the second listener position based on the metadata; determine at least two modified audio signals for the second listener position based on the at least two audio signals; determine spatial metadata for the listener position; and output the at least two modified audio signals and the spatial metadata.
