1. An integrated circuit being operably disposed between a plurality of audio sources and a signal processing circuit, the integrated circuit comprising:

  • a magnetic field sensor;

    a magnetic field threshold comparator and a magnetic field threshold value, the magnetic field threshold comparator being operably coupled to the magnetic field sensor and the magnetic field threshold value;

    a gate being operably responsive to the magnetic field threshold comparator, the gate including a plurality of gate inputs and a gate output, the plurality of gate inputs being operably coupled to the plurality of audio sources, and the gate output being operably coupled to the signal processing circuit, wherein one of the plurality of audio sources is selected to be presented to the signal processing circuit in response to the magnetic field threshold comparator output; and

    a manual override, operable to couple one or more of the plurality of audio sources to the signal processing circuit.
