Hear the difference now

The Dirac Live Room Correction Suite fundamentally improves the quality of your favorite audio when listening to HiFi systems connected to your computer. The Dirac Live Room Correction Suite is also perfect for professional audio.

  • 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 room correction software supports up to 24-bit resolution at 192 kHz sample rate. Our advanced algorithms are seamlessly integrated with user-friendly design, making it easy to use for anyone from casual users to experienced audio designers. Please read our Frequently Asked Questions for further information about how to get started.


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 stereo image, clarity and transient reproduction of the music.
The technology behind the Dirac Room 

Correction Suite, Dirac Live®, is a result of years of research into sound optimization. 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 digital cinema theaters.

Two software applications


Dirac Live Room Correction Suite consists of two software applications:



1. Dirac Live Calibration Tool


The Calibration Tool offers step-by-step instructions on how to measure and analyze the degradations in sound quality caused by your loudspeakers and listening environment. Correction data is generated automatically. The room calibration tool requires a microphone 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.
