Abstract: An apparatus comprising: an input configured to receive at least two groups of at least two audio signals; a first audio former configured to generate a first formed audio signal from a first of the at least two groups of at least two audio signals; a second audio former configured to generate a second formed audio signal from the second of the at least two groups of at least two audio signals; an audio analyser configured to analyse the first formed audio signal and the second formed audio signal to determine at least one audio source and an associated audio source signal; and an audio signal synthesiser configured to generate at least one output audio signal based on the at least one audio source and the associated audio source signal.

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.
