The audio processing unit further has a first filter unit and a first delay unit which is coupled to the first input, and a second filter unit and a second delay unit which is coupled to the second input. The audio processing unit further has an adding unit for adding signals from the first and second filter units and a control unit for influencing the filter parameters of the first and second filters and/or the delay times of the first and second delay units depending on an amplitude of an audio signal received via the first and/or second input. A directivity factor of the output signal of the microphone is controlled depending on the amplitude of the output signal of the microphone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio processing unit and method of processing an audio signal","description":"An audio processing unit having a first and second input for receiving output signals of a microphone with a first and a second physically symmetrically structured microphone capsule.
