An ambisonic recording uses a multi-capsule microphone to capture a spherical representation of sound from a single point.
Ambisonic recordings are captured in A-Format or B-Format.
A-Format is the raw audio captured from each capsule on the microphone.
B-Format 1st Order is the decoded audio, representing the spherical sound space with 4-channels: W, X, Y, Z:
B-Format 2nd Order is the decoded audio, representing the spherical sound space with 8-channels (more accurate spatial resolution):
Ambix 1st Order (B-Format)
Ambix 2nd Order (B-Format)
FuMa 1st Order (B-Format)
FuMa 2nd Order (B(Format)
Having the control of Ambisonic recordings enriches the environment far better than traditional stereo recordings, as it's quite easy to translate seemingly complicated 1st order / 2nd order, FuMa, Ambix to any format you wish: Stereo: Mid-Side, Binaural, Pantophonic, Periophonic, Quadraphonic, UHJ Stereo, 5.0, 7.0, and the list goes on.
