Improve your sound system with digital room correction

Whether you use a PC- or MAC, the Dirac Live Room Correction Suite™ software offers a clear improvement of your audio system by analyzing your speakers and room acoustics with the help of a measurement microphone. The software will then correct for colorations in the sound caused by your speakers and room. Choose between the Stereo Version, or the Full Version up to 8 speakers (home theater and surround system).

"there wasn't an aspect of the musical of reproduction that was not affected by the DSP; whereas the beauty is that it can be tailored to your specific preferences"

- John Brazier, Positive Feedback


Dirac Live Room Correction Suite:



  • Perfects sound in any listening room and puts you face to face with the recorded artist.
  • Gives your system a natural sound with increased musical and vocal clarity.


  • Deepens the bass, removes resonances and acoustic problems in sound reproduction.
  • Is a cost-effective alternative to expensive room treatments and sound system upgrades.

Dirac’s digital room correction software supports up to 24-bit resolution at 192 kHz sample rate. The software improves the sound quality when listening to Hi-Fi systems connected to your computer. See also system requirements & technical specifications. Our advanced algorithms are seamlessly integrated with user-friendly design, making it easy to use for anyone from casual users to experienced audio designers.

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.

Note: Version 1.2 for MAC is available for Dirac Live Room Correction Suite. The trial version for MAC is now extended to 30 days. Version 1.2 for PC is planned to be released soon.
