Abstract
A sound capture device comprises a symmetric microphone array that includes non-radially-oriented directional sensors (101). The device typically derives a spherical harmonic representation of the incident sound field, and affords higher signal-to-noise ratios and better directional fidelity than prior arrays, across a wide range of audio frequencies.
Claims41
A sound capture device comprising a plurality of microphone capsules disposed around a point of symmetry, including a first set of at least three microphone capsules each having an axis along which it exhibits maximum sensitivity, wherein the axes of the capsules in the first set do not all pass substantially through the point of symmetry and wherein the directions of the axes of the capsules in the first set are not all substantially coplanar.
