Analysis of Spatial Metadata From Multi-Microphones Having Asymmetric Geometry in Devices

摘要

An apparatus including a predetermined shape, the apparatus including at least three microphones, wherein at least one pair from the at least three microphones comprises including two microphones which are separated by a shorter distance of the predetermined shape than at least one other microphone pair of the predetermined shape; and a processor configured to: receive at least three microphone audio signals from the at least three microphones; analyse at least the microphone audio signals from the two microphones to determine a directional ambiguity decision; and analyse the microphone audio signals from at least one of the other microphone pairs to determine at least one sound characteristic other than the direction ambiguity.
