The Premium Sound System of Lear's in-show display vehicle will feature the trend-setting digital room correction technology Dirac Live™ developed by Dirac Research AB. The Dirac Live™ technology recently hit global roads as a feature of Lear's latest digital full class D audio amplifier which is currently available in the BMW M5 (also available with regular 5 series and M6 vehicles). A recent sound system review by the German magazine "Auto Motor und Sport" (Issue 8, March 28, 2007, pp. 146-148) named the sound in the new BMW M5 "with respect to stereo sound, the most impressive car stereo system in the world".

Dirac Live™ is a digital filter technology that optimizes staging, clarity and tonal balance by enhancing the sound system impulse response in all seats and applying a desired branded sound identity. The final result is a sound system with sophisticated tailoring of the audio signal to the complete sound system's acoustical properties delivering an in-vehicle sound experience with unsurpassed audio performance.

The joint Lear/Dirac display will be equipped to enable visitors to switch between automatically optimized Dirac Live™ FIR (finite impulse response) and manually tuned IIR (infinite impulse response) filters in real time, allowing a side-by-side comparison in the advancements in filter design technology and an audible perception of improved performance levels. Specialists of both Lear and Dirac will be available during the show to explain and demonstrate the technology to interested visitors.

In addition, Lear's Supreme Sound Demonstrator will highlight advancements in automotive sound technology that provides perfectly balanced sound for any seating position in a vehicle which produces a sound stage impression that seems to be completely detached from the vehicle speakers.

In connection to the AES Convention exhibition, representatives from both Lear and Dirac will daily give comprehensive seminars on the benefits of applying the Dirac Live™ product family in the development and design of automotive sound systems.
