Ambisonics is a full-sphere surround sound format: in addition to the horizontal plane, it covers sound sources above and below the listener. [ 1 ] [ 2 ] Unlike some other multichannel surround formats, its transmission channels do not carry speaker signals.
It consists of 19 omni-directional microphone capsules distributed on a sphere (up to third order Ambisonics microphone). ZM-1 microphone together with provided software delivers sound source separation possibilities, as well as optionally generating Ambisonic outputs up to third order. Sennheiser offers the FOA Ambeo tetrahedral microphone. It ...
Goodwin (2009) has suggested a slanted octahedron with separate front center (which he calls 3D7.1) [17] as an alternative way of using 7.1 systems to achieve with-height Ambisonic reproduction in games, and to allow reasonably accurate native 5.1 playback. An OpenAL game audio backend and decoder for this setup is commercially available. [18]
The Soundfield microphone is an audio microphone composed of four closely spaced subcardioid or cardioid (unidirectional) microphone capsules arranged in a tetrahedron. It was invented by Michael Gerzon and Peter Craven, and is a part of, but not exclusive to, Ambisonics, a surround sound technology. It can function as a mono, stereo or ...

Spherical Harmonics up to Ambisonic order 5 as commonly displayed, sorted by increasing Ambisonic Channel Number (ACN), aligned for symmetry. The traditional B-format only concerned itself with zeroth and first Ambisonic order. Because of a strong correspondence between the spherical harmonics and microphone polar patterns, and the fact that ...
