For Computer Audiophiles
Do you listen to your music via a computer and would you like to improve the sound quality of your present system? Then we can offer you something exclusive: Dirac Live® software to optimize the audio performance of your system, delivering the best possible sonic reproduction regardless of the environment.

• You measure the acoustic characteristics of your loudspeakers and your room using the Dirac Live Calibration Tool™ for PC or Mac, and a microphone.

• You can then play all your sound from your computer - regardless of media player - via the Dirac Audio Processor™. It acts like a virtual sound card and performs Dirac Live® room correction, adjusted to your preferences.

Dirac Live® Technology
Dirac Live® is a premium mixed-phase room and speaker correction technology that operates in the time- and frequency domain. Up until now it has been sold exclusively to manufacturers of sound systems and system integrators. It is for instance used in cinemas, studios, luxury cars, famous theatres, and luxury homes. Companies that use Dirac Live® technology include BMW, Naim Audio, Bentley, Datasat Digital Entertainment, Rolls Royce, Theta Digital, and Ken Kreisel Professional Sound. For the first time ever, Dirac Live® technology is now available for purchase directly by the end-consumer, through the introduction of Dirac Live Room Correction Suite™.

Impulse Response Correction
Unlike the commonplace minimum-phase room correction systems, Dirac Live® is a mixed phase technology. Other than performing a first class frequency response correction, it is also a time-domain controller. It can effectively correct for the impulse response of the sound system in a large listening area, a factor critical for accurate staging, clarity and bass reproduction. An accurate impulse response will also reduce listening fatigue.

Flexible Playback
Dirac Audio Processor™ works as a "virtual soundcard" and filters all the sound that is played from the computer, regardless of the application used. In other words there is no need for specific media players or plug-ins. You can always enjoy good sound using your favorite applications. Dirac Audio Processor™ is compatible with standard sound cards and computer DACs. It has four different quick-load slots, but allows an unlimited number of filters.

Musical Benefits
• A more accurate sound image/staging
• Improved musical clarity and voice intelligibility
• Reduced listening fatigue
• A more true-to-the-source music reproduction
• Better transient response yielding a deeper and tighter bass and removing the negative effects of room modes.
