A-format files are then processed through a calibration file unique for the individual microphone that make the recordings phase accurate and then these are converted into B-format where all 3 acoustical dimensions (back-front X, left-right Y, up-down Z) are defined plus the source point of reference. From the resulting B-format every microphone pattern and playback format can be created. The entire process once the files have been transferred to the computer takes seconds.

The following microphone patterns can be created omni, cardioid, hyper-cardioid, sub-cardioid, super-cardioid, figure-8; as well as multiple combination patterns – blumlein, height-enabled blumlein, Mid/Side, XY (two crossed cardioids) separated by any arbitrary angle, three hypercardioids facing forward and two cardioids facing rearward (for 5.1 surround).

The B-format files can be create in the following playback formats – mono (without phase cancellation), stereo, binaural, 4 and 6 sided array, 5.1 surround, 7.1 surround with height, 8 channel surround with height.
