Rolls Royce Ghost uses Dirac Live® sound correction to overcome car acoustic challenges
The Rolls Royce Ghost in-car entertainment is taken to new
heights by the use of premium sound correction technology Dirac
Live® in order to overcome room-acoustic challenges and
loudspeaker-related sound quality difficulties.
The car environment poses exceptional challenges in designing
reference-grade audio. Traditionally, sound quality in cars has
been hampered by things such as subpar loudspeaker locations, poor
acoustic properties of their cabins, and imperfect loudspeaker
housings. With the aid of the latest in digital control technology
combined with first-class audio components, the new Rolls Royce
Ghost delivers sound quality on par with the best in studio sound.
Dirac Live® is a digital sound optimization technology from Swedish
audio research think tank Dirac Research AB. It effectively washes
away these problems associated with reproducing music in cars.
Each loudspeaker has been acoustically measured in a dense
measurement grid inside the Ghost. A high-precision digital
controller has then been tailored to these particular loudspeakers
and the interior cabin environment with the aim of matching the
measured acoustic output to the sound on the recording as closely
as possible. Speaker resonances, room modes, early reflections, and
other acoustic flaws are removed, thereby reaching an exceptionally
transparent musical experience.
"Since music is all about timing, Dirac Live does not just
improve the tonal character but also makes sure that each part of
the performance has the same duration and timing as on the
recording. Traditional car acoustic limitations result in a
collapsed stereo image and lost clarity. This unnatural sound
causes listening fatigue. Dirac Live makes the music come alive
again", said Mathias Johansson, CEO of Dirac.
Dirac Live® is also used by, among others, BMW, Bentley and
high-end digital cinema theaters across the world to achieve the
finest in sound quality.
About Dirac Research:
Founded in 2001, Dirac Research is a premier R&D company
specializing in high-performance digital sound optimization, room
correction and sound field synthesis. The company was founded by
researchers from the Signals & Systems Group of Uppsala
University, Sweden, which has fostered 8 Nobel Prize laureates.
With Dirac's patented toolbox for efficient and accurate audio
system optimization, customers such as BMW, Bentley, Rolls Royce
and Datasat Digital Entertainment have achieved dramatically
improved sound quality and a shortened time-to-market. Dirac
Research maintains offices in Sweden, Tokyo, Detroit, San Diego,
