    Abstract: Embodiments include a microphone array comprising a first plurality of directional microphone elements arranged in a first cluster formed by directing a front face of said microphone elements towards a center of the first cluster, and a second plurality of directional microphone elements arranged in a second cluster formed by directing a front face of said elements away from a center of the second cluster, wherein the first cluster is disposed vertically above the second cluster. Also provided is a microphone comprising a first microphone array comprising a plurality of directional microphone elements arranged in close proximity to each other and configured to capture near-field sounds within a first range of frequencies, and a second microphone array disposed concentrically around the first microphone array, the second array comprising a plurality of omnidirectional microphone elements configured to capture near-field sounds within a second range of frequencies higher than the first range.

    Abstract: Embodiments include an array microphone comprising a plurality of microphone sets arranged in a linear pattern relative to a first axis and configured to cover a plurality of frequency bands. Each microphone set comprises a first microphone arranged along the first axis and a second microphone arranged along a second axis orthogonal to the first microphone, wherein a distance between adjacent microphones along the first axis is selected from a first group consisting of whole number multiples of a first value, and within each element, a distance between the first and second microphones along the second axis is selected from a second group consisting of whole number multiples of a second value.
