An electronic apparatus (100) is provided having a front side and a rear side oriented in opposite directions along a first axis, and a right-side and a left-side oriented in opposite directions along a second axis that is perpendicular to the first axis. A null control signal (565) is generated based on an imaging signal (585). A first microphone (530) located near the right-side of an electronic apparatus generates a first signal, and a second microphone (520) located near the left-side of the electronic apparatus generates a second signal. The first and second signals are processed, based on the null control signal, to generate a right beamformed audio signal (552) having a first directional pattern having at least one first null, and a left beamformed audio signal (554) having a second directional pattern having at least one second null. A first angular location (α) of the at least one first null and a second angular location (β) of the at least one second null are steered based on the null control signal.
