Abstract
Methods and apparatuses for capturing and encoding ambisonic audio are described herein. An example ambisonic microphone may comprise a first microphone capsule oriented substantially toward a first vertex of a notional tetrahedron, a second microphone capsule oriented substantially toward a second vertex of the notional tetrahedron, a third microphone capsule oriented substantially toward a third vertex of the notional tetrahedron, and a fourth microphone capsule oriented substantially toward a fourth vertex of the notional tetrahedron.
Claims20
An ambisonic microphone, comprising:
- a yoke comprising a protruding member defining an axis;
- and
- a plurality of microphone capsules coupled to the yoke along the protruding member, wherein:
- the plurality of microphone capsules is geometrically arranged to reduce an acoustic shading effect from a structural interference introduced by adjacent ones of the plurality of microphone capsules;
- and
- the plurality of microphone capsules is compactly nested along the axis defined by the protruding member to reduce a phase-related error.
An ambisonic microphone, comprising:
- a yoke comprising a protruding member defining an axis;
- a first microphone capsule coupled to the yoke along the protruding member, the first microphone capsule being oriented in a first direction that is substantially toward a first vertex of a notional tetrahedron;
- and
- a second microphone capsule coupled to the yoke along the protruding member, the second microphone capsule being oriented in a second direction that is substantially toward a second vertex of the notional tetrahedron,
- wherein the first and second microphone capsules are compactly nested along the axis defined by the protruding member to reduce a phase-related error.
