Dirac ART – State of the Art Raumkalibrierung

For more than a decade, audio enthusiasts have used Dirac Live to analyse the acoustic properties of a listening room, reduce the room's influence and improve speaker performance. Today, Dirac Live is an industry leader, available in some of the world's best-known AVR brands and used by home installers to deliver great sound in even the most challenging situations.

But what exactly does the Dirac measurement process do? What are the measurement methods and why is Active Room Treatment (ART) currently the ultimate measurement method to get the best out of your room and speakers?

Active room treatment to reduce fading in the room

Dirac Live room correction and bass control effectively deal with two different aspects of room-speaker interaction. Neither, however, addresses decay time throughout the listening room or the elimination of residual room resonance.

As audiophiles know, low frequencies are made up of long wavelengths that slowly fade in a small room such as a living room. This means that bass lingers in the room even after the speakers have stopped reproducing it, and it can take more than half a second for the bass to fully fade - much longer than intended. This results in washed-out and boomy bass which makes it difficult to distinguish notes clearly. The Dirac Live room correction improves the direct wave and reduces early reflections from the same direction.

The following graphic visualises the significantly reduced decay of bass frequencies due to Active Room Treatment.
