Techy Stuff

For those of you interested in such things, here's some extra details about the sound recording:



Soundfield Technology is based on the principle that all acoustic events can be represented by four basic elements. These are 'X' which is front/back information (depth), 'Y' which is left/right information (width), 'Z' which is up/down information (height) and 'W' the central point from which the other three elements are referenced. Collectively, W, X, Y and Z are entitled B-Format. Soundfield are the only microphones in the world which deliver B-format which can be stored on four tracks of any recorder.



The Soundfield microphone itself contains four capsules, mounted in a tetrahedral array. The Soundfield System relies upon B-Format and its processing at its core. B-Format is a 3 dimensional representation of acoustical events, all referenced from a single 'virtual' point source. The 3 dimensions are: X, Y, Z as noted above. B-Format offers these 3 dimensions as an individual output plus the point source reference W, across 4 channels. It is possible to alter mic position within the recording after it was recorded and generate a final stereo output. B-Format also provides multi-channel output capability.



So there. FBSG has the distinction of not only being the first ever Catalogue Raisonne to be published as a DVD but also the first ever to be recorded in 5.1 surround sound! Wowzers, whatever next - don't ask!
