• providing a primary first microphone input signal by the primary first microphone;
• providing a primary second microphone input signal by the primary second microphone;
• providing a secondary microphone input signal by the secondary microphone;
• determining a pinna output by the pinna restorer, wherein the act of determining the pinna output comprises:
• obtaining a first mixer input,
• obtaining a second mixer input, and
• determining a first mixer output based on the first mixer input and the second mixer input, wherein the pinna output is based on the first mixer output;
