Ladies & Gentlemen may i have your attention please
You are about to experience now in this theatre
the future of sound based on a revolutionary new system called Auro-3D
This is a three-dimensional audio technology that is changing the landscape of the cinematic experience
Auro-3D features sound reproduction that is more realistic than anything youve heard before
It draws you into the action on-screen fully immersing you in a spectrum of lifelike sound
Natural acoustic reflections affect you as they do in real life
originating not only from around But also above you
Spatial sound can be divided into 3 different layers
Sounds coming from the horizontal plane around us
Above this is a second layer that reveals both direct sounds and height reflections
These reflections are important for our brains to better understand the sounds originating in the first layer
And the third layer revealing sounds that come from directly above us
This reproduction channel is also known as the "Voice of God"-channel
Auro-3D achieved a reproduction system that uses these three layers to recreate the most
efficient three-dimensional sound format with the minimum number of speakers
Welcome to Auro-3D
Consider the beginnings of cinematic sound
Early films were presented in mono
At first cinema audio was restricted to voices and
simple sound effects coming from the center of the screen much like the voice track you
are hearing now
The introduction of Stereo Sound made it possible to produce sounds traveling between the left
and right sides of the screen from the left to the center to the right
People believe that Stereo is two-dimensional sound but it in actuality it is one-dimensional sound
This is because all audio originates from a SINGLE line or horizontal axis located in
front of the audience
Surround sound adds a second dimension by placing speakers on the y-axis around the
length of the auditorium
It is an arrangement that creates a single auditory plane around the listener
Both 5.1 and 7.1 Surround Sound are actually TWO dimensional sound formats and not 3 dimensional
as commonly believed
Of course this 2D sound gives the audience the feeling
that they are closer to the action
The problem is that 2D sound doesn't quite feel natural
To fully realize Sound in 3D we include the missing dimension
Height
Auro-3D incorporates Height Channels as well as a top channel above the audience to truly
deliver a authentic three-dimensional sound experience
It is based on a groundbreaking new technology that delivers with the magic of uncompressed
audio quality on all 3 layers and with 12 independent channels
Now you can clearly hear sounds coming from both around and ABOVE the audience
Wow! Did you hear that? The reflections created by the exclusive height channels make things
sound pretty real Don't they? This is where much of Auro-3Ds magic lies
Ceiling speakers alone are not enough to get a true three-dimensional audio effect
The Surround channel - with height speakers and ceiling speakers - allow for the creation
of a more natural reproduction of Sound in Space
This results in a totally new cinema experience that is easily built on a theaters existing
5.1 Surround system
With the simple addition of speakers on the height channels
these three-dimensional sounds are much more easily achieved
Here are some examples of Auro-3D in action
By making use of the height channels Auro-3D delivers surprisingly real audio effects
But Auro-3D also features an important third layer above the audience
Sometimes we call that the Voice of God channel which allows the reproduction of sounds coming
from directly the listener
Here are two examples of recordings made at an airport
Experience how capable the Auro-3D system is at reproducing the exact position of an
airplane as it passes by - from taking off to flying directly overhead and finally disappearing
above and behind you
In this next demo helicopters will slowly creep up from the
back of the theater
Close your eyes and feel them fly overhead
Without Back Height Surround speakers it is impossible to reproduce natural fly-over effects
Auro-3D makes cinema feel like youre really there
participating in the action
From subtle nature environments to music and the rumblings of our mechanized world
the emotional impact provided by height information can now unfold around you
Previously unattainable levels of cinematic immersion are now possible
The natural effect of three-dimensional sound has the power to captivate audiences like never before
Together with Barco Auro Technologies brings you the cinema sound
of the future
