The Brahma microphone is a high quality electrets based, phase accurate sound field microphone that captures the true 3-dimensional representation of an acoustical ambience. The four capsules are flush mounted on the 4 virtual faces of a truncated tetrahedron in a Teflon ball. The entire electronic structure is further shielded in a satin finished stainless steel mesh and two-piece ring.

Brahma microphone offers superior audio quality. It recreates sound as heard from a single point, in all directions, in any sonic field. The sound image can be panned, tilted and zoomed, as well as any microphone pattern can be created from one recording. It is the single most versatile microphone, as well as the most flexible option for creating multi-channel sound.

The microphone is a single point recording device that records 4 directional sonic inputs in a cardioid pattern, (these files are known as the A-format) onto any 4 channel recorder. These 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.

An additional advantage the Brahma has over stereo microphones or stereo images from 2 or more microphones is that the capsule error between multiple capsules is much smaller and resolved in the calibration files, thus there are no set-up or placement issues.
