Abstract: A mobile device comprises an input configured to receive at least two microphone signals associated with at least one acoustic source. An audio source determiner determines from at least part of the at least two microphone signals at least one audio source based on the at least one acoustic source and an audio source direction determiner determines at least one direction associated with the determined at least one audio source. A calibrator calibrates at least one of the at least two microphone signals based on the at least one determined direction.
