Dirac Live™—A New Approach to Room Correction Algorithms

A method for improving car audio systems through digital correction of the impulse/frequency responses of individual loudspeakers is presented. The ability to simultaneously optimize different time and frequency domain criteria and flexible spatial averaging are the main benefits of the new approach. The solution is featured in the new BMW M5 Individual High End Sound System, recently reviewed by Auto, Motor und Sport (number 8/2007 pp. 146-148) stating: “the most impressive car stereo sound in the world.” An A/B comparison to conventional filtering is available in LEAR’s demo car in our common exhibition booth.
