Dirac Live
What is Dirac Live®?

Loudspeakers and rooms in which they are placed inevitably introduce coloration on the reproduced sound. These colorations are sometimes very difficult or impossible to remove with traditional hardware design and room treatments. Dirac Live® is advanced patented software technology that analyses the speakers as well as the room and corrects these colorations with an amazing improvement as result. We call this "room correction."

What are the benefits of Dirac Live?

In short, your speakers will become better and the negative room effects will be reduced. In detail, these are some of the more specific benefits that can be experienced:

• Improved staging (localization of sound events)

• Better clarity and intelligibility in music and vocals

• A deeper and tighter bass without resonances.  • Expanded frequency range

• Reduced listening fatigue

• Improved dynamics • Reduced negative influence of   the room• Choose your own character of sound


With ten thousands of hours optimizing their DSP algorithms in over 10 years, Dirac have created a solid reputation in the HiFi industry. They have been working with famous brands like : BMW, Bentley, Rolls Royce, Naim, Datasat (DTS), Theta Digital, Pioneer, Olympus, Xiaomi etc


With the Dirac Live® software you get the same optimization ”power” as surround processors in the price range of 15 000 Euro !

Free trial version

Dirac live® gives you an unbeatable combination of user friendliness and performance that no competitor can match and the good news is that you can download a free trial version and try it out for two weeks. All you need is a calibrated microphone like XTZ Microphone Pro and the Dirac Live® software to get started.

Dirac Live® can be downloaded here!


The software consisting of the measurement software Dirac Live® and the virtual sound card Dirac Audio Processor™ is incredibly intuitive to use and guides you step by step through the entire measurement process. When the process is completed, it’s easy to turn the correction on and off to compare the difference. You can also change the corrections manually for your more personal taste in sound.

Dirac Audio Processor™ to MAC och PC:

Dirac Audio Processor™ acts as a virtual sound card and allows you to apply your optimized correction filters (from Dirac Live®) on all audio playback from your PC or Mac. You can easily switch between these correction filters while listening, to easily hear which filter that sounds best to you.

About Dirac Research

Dirac Research AB was founded in 2001 and is a research and development company specialised in high performance sound optimization, room correction and sound field synthesis. The company was founded by scientists from the Signals & Systems group at Uppsala University.

Dirac's patented toolbox for efficient and accurate audio system optimization have helped customers such as BMW, Bentley, Rolls Royce and Datasat Digital Entertainment™ to achieve a dramatic improvement in their sound quality.

Recomendations from partner and media:

"I have worked with Audyssey, Dirac, TACT, DSPeaker, DEQX and am presently looking at Bohmer. Thus far, my favorite is Dirac with TACT running second."

- Bill Dudleston, Chief Designer and Owner of Legacy Audio

"This software, in less than a day, has made my desktop system sound better than I've been able to make it sound after years of traditional optimization!."
- Ken Rockwell, kenrockwell.com photography blog

"Our customers expect the ultimate in every experience and Dirac provides the ultimate within digital signal processing."

- Mike Hanks, Senior Engineer at Bentley Motors

"I always wondered what my system would sound like in a room optimized for acoustics. Unfortunately I can not make my living room look like a studio. Instead I downloaded the trial version and tried it out. After two weeks it was hard to live without the room correction program from Dirac, the sound was more organic and natural to my ears. It is a lot of money but still worth every penny".

- Kareem Shawwaf, end-user, Sweden

 "I was completely amazed by the difference that Dirac made to my new studio. My speakers are great but have several acoustic issues in my new studio resulting in the mixes not translating as expected, it was a friend who recommended I try Dirac. Now everything sounds just right!... significantly more accurate across the whole frequency range plus the imaging is incredible"

- Ian Wallman, record producer (Ivor Novello nominated), UK


"The proof of all this pudding was in the listening, and it was delicious."

 - Kalman Rubinson, Senior Contributing Editor, Stereophile


"Når filteret kom på forsvandt støjen i bas området og det hele stod mere klart. Jeg kunne meget tydeligere høre dynamikken i bassen og hvordan bassisten slog på strengene."

- Søren Bertram Pedersen, recordere.dk


"By being able to manipulate the program's curves, I was able to voice my speakers in such a way that I actually felt the closest I've ever been to being in a concert hall."

"I am extremely excited with the immediate and obious improvements Dirac Live brought to my system. It took some work to find an optimum filter, but once dialed in, the benefits are significant."

- Frank Berryman, ultrahighendreview.com


"I found Dirac Research’s Live RCS every bit as useful for a computer-driven audio system as Audyssey’s softwares are for home theater. I can’t foresee ever again usi
