A sound processing system comprising: a first audio capture device and a second audio capture device, wherein the first audio capture device is located in closer proximity to a point of interest than the second audio capture device; a voice activity detection module to: receive first and second audio feeds respectively captured by the first and second audio capture devices; attenuate at least a portion of the first audio feed based on a corresponding portion of the second audio feed to generate a first attenuated audio feed; attenuate at least a portion of the second audio feed based on a corresponding portion of the first audio feed to generate a second attenuated audio feed; compare frequency bands of the first attenuated audio feed with corresponding frequency bands of the second attenuated audio feed; and determine a source confidence level based on a number of the frequency bands from the first attenuated audio feed that exceed a predefined threshold of difference from the corresponding frequency bands of the second attenuated audio feed, wherein the source confidence level is indicative of whether sound is originating from the point of interest. a first audio capture device and a second audio capture device, wherein the first audio capture device is located in closer proximity to a point of interest than the second audio capture device; a voice activity detection module to: receive first and second audio feeds respectively captured by the first and second audio capture devices; attenuate at least a portion of the first audio feed based on a corresponding portion of the second audio feed to generate a first attenuated audio feed; attenuate at least a portion of the second audio feed based on a corresponding portion of the first audio feed to generate a second attenuated audio feed; compare frequency bands of the first attenuated audio feed with corresponding frequency bands of the second attenuated audio feed; and determine a source confidence level based on a number of the frequency bands from the first attenuated audio feed that exceed a predefined threshold of difference from the corresponding frequency bands of the second attenuated audio feed, wherein the source confidence level is indicative of whether sound is originating from the point of interest. receive first and second audio feeds respectively captured by the first and second audio capture devices; attenuate at least a portion of the first audio feed based on a corresponding portion of the second audio feed to generate a first attenuated audio feed; attenuate at least a portion of the second audio feed based on a corresponding portion of the first audio feed to generate a second attenuated audio feed; compare frequency bands of the first attenuated audio feed with corresponding frequency bands of the second attenuated audio feed; and determine a source confidence level based on a number of the frequency bands from the first attenuated audio feed that exceed a predefined threshold of difference from the corresponding frequency bands of the second attenuated audio feed, wherein the source confidence level is indicative of whether sound is originating from the point of interest.
