Soundfield microphone

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 surround sound microphone, optionally including height information.

The Soundfield microphone was invented by Michael Gerzon and Peter Craven.

In 2016, the parent company of RØDE Microphones, The Freedman Group, acquired SoundField from then-owner TSL Products.

By combining the signals in various proportions, it is possible to derive any number of first-order microphones, pointing in any direction, before and after recording.

Examples of software that perform these calculations are Visual Virtual Microphone,[4] SoundField's Surround Zone[5] and Ambisonic Studio's B2X decoders[6] plug-ins.

Again in post-production, the B-format recording can be decoded to any number of speakers arranged in both the horizontal and vertical planes.

The A-Format is the signals from four microphones on the faces of a tetrahedron .
