SURROUND SOUND EXPLAINED * PART 3
Though mercial failure in the 1970s, the Ambisonics surround sound
system was technically flawless, and survives to this day -- indeed, today it
is more relevant than ever. Hugh Robjohns unravels the mysteries of the B-
format...
Before turning my attention to modern surround systems
and how they work, I'd like to spend one more instalment of
this series explaining another form of surround sound that
pre-dates -- Ambisonics. This system is finally beginning
to enjoy recognition for its undoubted strengths, proving it
really was way ahead of its time.
Ambisonics was conceived in the late 1960s as plete
recording and reproduction system capable of recreating
accurate three-dimensional sound stages from original
recordings. The format was developed plex
mathematics and psychoacoustics, all based on the original work on coincident stereo led
by Alan Blumlein in the early 1930s (see the 'History' box elsewhere in this article for more
on the system's development).
Ambisonics failed to attract the significant attention of either manufacturers or the public in
the '70s, principally because too panies had had their fingers burned by the
quadraphonic fiasco (see part 1 of this series, in SOS August 2001). Fortunately, the
