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 first pair of microphone capsules arranged in a first vertical plane and sharing a first intersecting axis,
- wherein respective axes of maximum sensitivity of the first pair of microphone capsules are orthogonal to one another;
- and
- a second pair of microphone capsules arranged in a second vertical plane and sharing a second intersecting axis,
- wherein respective axes of maximum sensitivity of the second pair of microphone capsules are orthogonal to one another, and
- wherein the second vertical plane is oriented 90 degrees relative to the first vertical plane.
An ambisonic microphone, comprising:
- a yoke comprising a protruding member defining an axis;
- a first pair of microphone capsules coupled to the yoke along the protruding member, the first pair of microphone capsules comprising a first set of axes of minimum sensitivity that intersect at a first point in space;
- and
- a second pair of microphone capsules coupled to the yoke along the protruding member, the second pair of microphone capsules comprising a second set of axes of minimum sensitivity that intersect at a second point in space,
- wherein the first point in space is offset from the second point in space.
An ambisonic microphone, comprising:
- a plurality of microphone capsules configured to generate a set of audio signals in a first format;
- one or more processors;
- memory storing instructions that, when executed by the one or more processors, cause the ambisonic microphone to encode the set of audio signals from the first format to a second format using time-domain processing to generate a set of encoded audio signals;
- and
- an output port configured to provide the set of encoded audio signals to an external device.
