US Patent 11631422 Methods, apparatuses and computer programs relating to spatial audio

An apparatus is disclosed, configured to receive, from first and second spatial audio capture apparatuses, respective first and second composite audio signals comprising components derived from one or more sound sources in a capture space. The apparatus is further configured to identify a position of a user device corresponding to one of first and second areas respectively associated with the positions of the first and second spatial audio capture apparatuses, and to render audio representing the one or more sound sources to the user device, the rendering being performed differently dependent on, for the spatial audio capture apparatus associated with the identified first or second area, whether or not individual audio signals from each of the one or more sound sources can be successfully separated from its composite signal.
