Acoustic sound field synthesis technology revolutionizes the in-car audio experience
Uppsala, Sweden - October 19th, 2010-Dirac Research, a world
leader in room correction and sound field synthesis, has announced
the introduction of Dirac Dimensions, the most advanced digital
signal processing solution ever engineered for automotive high
fidelity. Dirac Dimensions virtually alters loudspeaker positioning
to suit each automotive interior, providing an expanded acoustic
environment and perfectly balanced sound from every seat in the
car. One stumbling block to achieving the benefits of sound field
synthesis has been that the technology requires too many
loudspeakers for real-life applications. Dirac Dimensions is the
first solution that uses the car''s existing loudspeakers to
deliver the advantages of sound field synthesis, and the technology
is available now in the 2011 Bentley Continental GT.
How Dirac Dimensions works
Dirac Dimensions is the first in-car audio optimization system to
offer true MIMO (multiple-input multiple output) control of the
entire sound field. Frequency response, spatial attributes, impulse
responses, and the acoustic summation of all loudspeakers are
optimized jointly to deliver the most realistic audio reproduction
possible.
Sound engineers at Dirac Research team with automotive
manufacturers to analyze acoustic properties within the car using
the Dirac Dimensions Measurement and Design Tool. Based on the
results, engineers can then "draw" an optimal listening environment
in the Dirac Dimensions Room Editor, placing virtual speakers at
desired locations while defining other target parameters for the
desired performance. The result is balanced, accurate sound
seemingly decoupled from the physical loudspeakers and extending
beyond them in every direction.
Automotive Applications
Dirac Dimensions is the ultimate solution for creating the perfect
stereo or 5.1 audio experience across all seating positions in an
automotive environment. Dirac Dimensions succeeds in overcoming the
limitations of conventional car speaker placement by using patent-
pending control algorithms to create virtual loudspeakers outside
the car while evening out response variations throughout the
passenger cabin. The result is the most lifelike listening
experience ever achieved for any automotive environment.
The ultimate in sophistication and performance, the 2011 Bentley
Continental GT utilizes Dirac Dimensions optimization technology to
transform the in-car listening experience. "Our technology
optimizes the sound field to achieve an unprecedented sense of
space and 
realism from all seating
positions in the car," said Mathias Johansson, CEO and CTO at Dirac
Research. "Dirac Dimensions actually transforms the output of the
existing loudspeakers to create an entirely new listening
environment. Due to its effectiveness and adaptability, we
anticipate an increased demand for Dirac Dimensions in home,
commercial and automotive applications," Johansson added.
