Abstract:
Embodiments of the disclosure generally include a method and apparatus for receiving and separating unwanted external noise from an audible input received from an audible source using an audible signal processing system that contains a plurality of audible signal sensing devices that are arranged and configured to detect an audible signal that is received from any position or angle within three dimensional space. The audible signal processing system is configured to analyze the received audible signals using a first signal processing technique that is able to separate unwanted low frequency range noise from the received audible signal and a second signal processing technique that is able to separate unwanted higher frequency range noise from the received audible signal. The audible signal processing system can then combine the signals processed by the first and second signal processing techniques to form a desired audible signal that has a high signal-to-noise ratio throughout the full speech range.

Claim (Index 17):
A method of processing an audible signal received from an external audible source, comprising:\n receiving a composite audible signal from each of a plurality of microphones disposed within a non-linear array of microphones from the external audible source that is positioned in a first direction from the non-linear array of microphones, wherein the plurality of microphones comprise a first microphone, a second microphone, a third microphone and a fourth microphone; and forming an audible signal that has an improved signal-to-noise ratio as compared to the received composite audible signal, wherein the formed audible signal is generated by:\n receiving direction information relating to the first direction; \n combining at least portion of the composite audible signal received by the first microphone with at least portion of the composite audible signal received by the second microphone to form a first combined audible signal, wherein the third microphone, the fourth microphone and a point positioned on a line that extends between the first microphone and the second microphone are all aligned along a direction that is substantially parallel to the first direction; \n delaying a portion of the composite audible signal received by the third microphone a predetermined delay time; \n inverting the delayed composite audible signal to form a first inverted audible signal; \n combining the first inverted audible signal and the first combined audible signal to form a second combined audible signal; \n delaying a portion of the composite audible signal received by the fourth microphone a predetermined delay time; \n inverting the delayed composite audible signal to form a second inverted audible signal; \n combining the second inverted audible signal and the composite audible signal received by the third microphone to form a third combined audible signal; \n delaying a portion of the third combined audible signal a predetermined delay time; \n inverting the delayed third combined audible signal to form a third inverted audible signal; and \n combining the third inverted audible signal and the second combined audible signal to form the fourth combined audible signal; and \n providing a fourth combined audible signal to a software application and/or electronic device that is configured to perform an audible signal processing activity based on the receipt of the fourth combined audible signal.
