Patent ID: 8503694

Claim:
A method for processing audio signals, comprising: capturing a sound at a first microphone oriented in a first direction to generate a first audio signal; capturing the sound at a second microphone oriented in a second direction, different than the first direction, to generate a second audio signal; computing a first probability indicative of a likelihood that the sound was emitted toward the first microphone, comprising: comparing a first feature of the first audio signal to a first feature of the second audio signal to derive a first feature probability, and determining a trust level for the first feature probability to determine a contribution of the first feature probability to the first probability; computing a second probability indicative of a likelihood that the sound was emitted toward the second microphone; altering the first audio signal as a function of the first probability to generate a first enhanced audio signal; and altering the second audio signal as a function of the second probability to generate a second enhanced audio signal, the second audio signal altered in a different manner than the first audio signal such that the second audio signal is suppressed relative to the first audio signal when there is a greater likelihood that the sound was emitted toward the first microphone than toward the second microphone.
