Pairwise audio capture device selection

A microphone selection system, comprising:

• an interface configured to receive audio information captured via a plurality of audio capture device pairs, wherein each audio capture device pair comprises a first audio capture device and a second audio capture device, wherein neither the first audio capture device nor the second audio capture device is included in any of the other audio capture device pairs of the plurality of audio capture device pairs, and wherein a first axis along which at least a first pair of the audio capture device pairs are positioned crosses a second axis along which a second pair of the audio capture device pairs are positioned;
• a processing system configured to, based on the audio information, determine a difference in audio energy between audio captured by the first and second audio capture devices for each of the plurality of audio capture device pairs and select an audio capture device pair of the plurality of audio capture device pairs having the largest difference in audio energy.
