What is Dirac Live?
Dirac Live is an advanced room correction and sound optimisation technology that dramatically improves your audio experience. By analysing how sound behaves in your space, it automatically adjusts your speakers to eliminate distortion, correct timing issues, and balance the overall sound.
When integrated with an AVR, Dirac Live measures the acoustic characteristics of your space using a calibrated microphone, analysing how sound interacts with the room. It then adjusts the speaker’s output to ensure that the sound is balanced and true-to-source, regardless of the room’s shape, size, or materials. This process includes aligning the timing and phase of the speakers to provide a cohesive, immersive sound field—something that would be impossible to achieve with just speaker placement alone.
Contrary to basic EQ systems that mainly flatten the frequency response, Dirac Live corrects both the frequency and impulse response. This means it not only addresses tonal balance but also ensures that transient sounds (like a clap or a drum hit) are reproduced cleanly without smearing or delay. With its capability to adjust for phase issues between speaker drivers, Dirac Live creates a more accurate and immersive audio experience that feels more natural and more true to the recording . By using Dirac Live, you’re essentially enhancing the performance of your sound system by making the sound more realistic and detailed, even in challenging spaces.
