Movie
Surround Formats
A good movie soundtrack is a complex interplay of sound fields:
the actors’ voices clearly fixed on the screen, the sound
effects positioned according to where they would be if the audience
was in the middle of the scene, and the music enveloping the
audience in a natural manner. The soundtrack is “designed”
in a dubbing theater that has sound mixing and movie screening
equipment, and encoded with one or more of the movie sound formats. |

Movie Theater Sound Versus Home Theater Sound
The major difference between a movie theater and a home entertainment
room is the size. If theater sound was reproduced with no modification
in a home, there would be a big difference in the feeling of scale.
Another difference is in the number and positioning of the speakers.
In a movie theater, the sound is designed so that it can be accurately
reproduced using numerous speakers embedded in the left, right and
rear walls and positioned so that they emphasize the relationship
between sound from the screen and from each channel. This provides
a more uniform quantity of sound to the wide audience area.
The
advantage of CINEMA DSP is that it complements and expands the Dolby-
and DTS-processed sound to overcome the differences in facilities,
acoustics and dimensions between movie theaters and home listening
rooms. In other words, it is able to preserve the localization and
directionality of the sound track as it was created by the movie
sound designer, while creating a soundscape that gives the sensation
of being as expansive as in a real theater.
