Patent ID: 8300845

Claim:
An electronic apparatus having a rear-side and a front-side, the electronic apparatus comprising: a first microphone that generates a first signal; a second microphone that generates a second signal; a third microphone that generates a third signal; an automated balance controller that generates a balancing signal based on an imaging signal; and a processor, coupled to the first microphone, the second microphone, the third microphone, and the automated balance controller, that processes the first signal, the second signal, and the third signal to generate: a left-front-side beamformed audio signal having a first major lobe with a left-front-side gain, a right-front-side beamformed audio signal having a second major lobe with a right-front-side gain, and a third beamformed audio signal having a third rear-side gain, wherein an audio level difference between the third rear-side gain and both the right-front-side gain and the left-front-side gain is controlled based on the balancing signal.
