2011 Bentley Mulsanne promises best in-car sound with Dirac Live DSP tech

Article by Christian Andrei, on September 21, 2010

Customers availing of the Naim for Bentley sound system option for their 2011 Bentley Mulsanne will be treated to Dirac Live sound optimization from Swedish Dirac Research. Ever since the partnership was inked between Bentley and Naim in 2008, the sound system has already been updated a number of times.

The latest of these updates would be the addition of the Dirac Live sound optimization technology, which was recently launched in digital cinema theatres around the world. Dirac Live works by getting rid of sound quality imperfections that result from room acoustics of the vehicle.

It then digitally tunes each loudspeaker to attain the most optimized level of sound quality. Dirac Live optimizes the system's transient reproduction -- unlike the conventional equalizers and sound correction systems – resulting to a more defined sound, clearer music, more balanced tone and tighter bass.

Technically, Dirac Live is a mixed-phase sound correction technology that rectifies the impulse response and then optimizes the frequency response of the sound system according to the measured acoustics in the vehicle.

Paul Stephenson, Managing Director at Naim, remarked that by employing Dirac's DSP technology, the company was able to bring the Naim experience to life even within the confines of a car, thereby creating a system that is vastly superior to other in-car audio systems and is considered to be at par with the best in-home hi-fi systems in the world.

On the other hand, Bentley Motors' Senior Engineer Mike Hanks remarked that the Dirac provides the best digital signal processing.

On his part, Mathias Johansson, CEO and CTO at Dirac Research, said that his company is proud to be part of the vision of Bentley and Naim to deliver an in-car audio system that is at par with the world's finest home hi-fi.

Bentley Aims for World's Best in-Car Sound With Dirac Live(R) DSP Technology

The all-new 2011 Bentley Mulsanne will feature Dirac Live(R) sound optimization in the Naim for Bentley sound system option.

In 2008, Bentley and Naim crafted an exclusive partnership with the aim to achieve the world's best in-car audio experience. By the release of the new flagship Bentley - the 2011 Mulsanne - several updates were introduced to take the system to yet a new level. In terms of sound quality, a key addition is the Dirac Live sound optimization technology from Swedish Dirac Research. This technology was also recently introduced in digital cinema theatres around the world to enhance cinema sound.

"Both Bentley and Naim are known for their mixture of the finest hand-built quality and cutting-edge technology. We feel privileged to be a part of their vision to deliver the equal of the world's finest home hi-fi within a car," said Mathias Johansson, CEO and CTO at Dirac Research.

Dirac Live removes sound quality imperfections that arise from the room acoustics of the car and digitally tunes each loudspeaker to reach the highest level of performance. Unlike equalizers and other room correction systems, Dirac Live optimizes the sound system's transient reproduction. The result is a more defined sound stage, musical clarity, tonal balance and tightness of bass.

"By harnessing Dirac's DSP technology we have been aided in our quest to bring the Naim experience to life within the environment of the car. In doing so we have succeeded in creating a system that is not only superior to other in-car audio systems available today but that also equals the world's best in-home hi-fi systems," said Paul Stephenson, Managing Director at Naim.

Mike Hanks, Senior Engineer at Bentley Motors adds: "Our customers expect the ultimate in every experience and Dirac provides the ultimate within digital signal processing."

On a technical level, Dirac Live is a mixed-phase sound correction solution, which corrects the impulse response and optimizes the frequency response of the sound system based on detailed acoustical measurements in the car.
