The result of years of research

 
 

Dirac Live is different than traditional minimum-phase room correction systems that only correct frequency response, but not impulse response. Dirac Live corrects both, thus offering improvements in the room acoustics, the stereo image, clarity and transient reproduction of the music.
The technology behind Dirac Live digital room 

correction, Dirac Live®(sound technology description), is a result of years of research into sound optimization. The market leader in room correction, this advanced digital signal processing algorithm is used in high-end AVRs, in luxury car sound systems such as Rolls Royce, BMW, and Bentley as well as in thousands of high-end digital cinema theaters across the world.

The room correction software consists of two applications

1. Dirac Live Calibration Tool

 

This room calibration tool offers step-by-step instructions on how to measure and analyze the degradations in sound quality caused by your loudspeakers and listening room. Correction data is generated automatically. The room calibration tool requires a microphone (see recommended room calibration microphones here) for the measurements and works with standard and USB sound cards (DACs). If you don’t want to get technical, just take the measurements and let the software figure out the rest! If you’re an advanced user, you can edit the target frequency response in detail.

2. Dirac Audio Processor

This application lets you apply the created correction data to all sound that is played from your computer, regardless of media player or application.
