Analysis of spatial metadata from multi-microphones having asymmetric geometry in devices

A method for an apparatus comprising a predetermined shape, the apparatus comprising:

• at least three microphones, located on or within the apparatus, wherein at least one pair of the at least three microphones comprises two microphones which are separated with a shorter distance of the predetermined shape than one or more other microphone pair, the method comprising:
• receiving at least three microphone audio signals from the at least three microphones;
• analysing at least the microphone audio signals from the two microphones which are separated with the shorter distance to determine a direction ambiguity decision;
• and
• analysing the microphone audio signals from at least one pair of the one or more other microphone pair to determine at least one sound characteristic other than a direction ambiguity, wherein the at least one pair of the one or more other microphone pair comprises two microphones separated with a longer distance of the predetermined shape in such a way that the two microphones separated with the longer distance are configured to capture spatial audio signals, wherein the at least one sound characteristic comprises at least a direction angle of arriving sound, wherein the direction angle of the arriving sound has at least one ambiguous value, and wherein the direction ambiguity decision is configured to at least partially resolve the at least one ambiguous value.
