Listening to the 7.1-channel surround as processed by the
JVC DAP (Digital Acoustics Processor) evokes a totally
different surround sound experience from what you get
from stereo or 5.1-channel sound. Listen carefully to the
5.1-channel sound of a DVD in its recorded form and
you’ll notice it does not produce the sensation of being
surrounded by sound.
JVC developed the DAP for one objective: to make the
home theater audience feel as if they were in the best
movie theater surrounded by an array of speakers to the
left and right, and behind. Then they would feel enveloped
in sound, with a helicopter, for instance, moving left to
right, or front to back.
JVC exclusive DSP, as implemented by the TI Aureus™
chip -- embodies the algorithms of sound field recreation
that are developed specifically for advanced home theater
receivers. The sound field patterns are created on the
basis of the computer sound field simulation technology
developed by a leading concert hall construction company.
Patterns of reflections are calculated based on the data of
the sound fields of the concert halls, theaters and movie
theaters.
*To verify simulated halls, the contractor creates a precision scaled-down
miniature hall using the same materials for walls, seats, etc., in the same
shape. A second larger scaled-down model will then be made to further
refine the data.
