Digital Room Correction

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 sound optimization suite includes digital room correction in order to help 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.


Dirac Live® room correction technology offers clear sound improvement regardless of the listening room, putting the listener face-to-face with the artist. The technology is available for purchase for consumers as well as licensing for manufacturers and OEM's. Buy Dirac Live Room Correction Suite>

Dirac Room Calibration, our newly developed room correction technology, is tailored for Android and iOS devices, featuring a user-friendly app and high level room correction capability. It will only be licensed to manufacturers and OEM’s and hence not available for purchase on our online store.


“ I was completely amazed by the difference that Dirac made to my new studio. ” 

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


“ Letter to the King was my 10th feature film as a sound designer, my first with Dirac Live as wingman and I don’t think I will ever do a film without that filter turned on. 

- Carl Svensson, Sound designer and mixer
