DPD Van and application


Dirac specializes in digital sound optimization solutions. Whether you’re watching a movie at home, relaxing with headphones or using your mobile device as a makeshift boombox, audio quality can make or break the experience. Great recording and production studios understand that exceptional loudspeakers don’t guarantee exceptional audio. Room acoustics are the weakest link in most sound systems, making acoustic sound treatment a must. Dirac’s digital room correction helps your loudspeakers reach their full potential in any listening room – perfect for manufacturers who want to provide the best possible audio solution across any price range.

With Dirac Live® you can easily measure the acoustic characteristics of your loudspeakers and room, and calibrate the sound system to reproduce sound as intended.


Whether you use the mobile or desktop app, Dirac Live offers a clear improvement of your audio system by analyzing your speakers and room acoustics with the help of a measurement microphone. The software then uses this data to build an acoustic model of the listening environment and detects the deficiencies. After careful analysis, Dirac Live corrects for both the timing and amplitude aspects of the colorations in sound to deliver a uniquely pristine listening experience.

  • Mixed-Phase Room Correction technology with Impulse Response Correction
  • Improved staging (localization of sound events)
  • Better clarity and intelligibility in music and vocals
  • A deeper and tighter bass free of resonances throughout the entire listening area
  • Ability to upload and choose the custom NAD target response
