    摘要： Embodiments include a planar microphone array comprising a first linear array arranged along a first axis; and a second linear array arranged along a second axis orthogonal to the first axis, a center of the second linear array aligned with a center of the first linear array, wherein each of the first linear array and the second linear array comprises a corresponding first set of microphone elements nested within a corresponding second set of microphone elements, and each set of microphone elements is arranged symmetrically about the center of the corresponding linear array, such that the first linear array and the second linear array are configured to generate a steerable directional polar pattern, the microphone elements of each linear array configured to capture audio signals. Embodiments also include a microphone system comprising the same and a method performed by processor(s) to generate an output signal for the same.

    摘要： Embodiments include a microphone array with a plurality of microphone elements comprising a first set of elements arranged along a first axis, comprising at least two microphone elements spaced apart by a first distance; a second set of elements arranged along the first axis, comprising at least two microphone elements spaced apart by a second, greater distance, such that the first set is nested within the second set; a third set of elements arranged along a second axis orthogonal to the first axis, comprising at least two microphone elements spaced apart by the second distance; and a fourth set of elements nested within the third set along the second axis, comprising at least two microphone elements spaced apart by the first distance, wherein each set includes a first cluster of microphone elements and a second cluster of microphone elements spaced apart by the specified distance.
