Dirac HD Sound - Overview 

What is Dirac HD Sound?
There are physical constraints present in all mechanical systems. Loudspeakers and earphones are by nature mechanical and it is therefore impossible to make a perfect loudspeaker - there will always be coloration on the sound, regardless of the price and quality. Dirac HD Sound® is advanced patented software technology that analyzes and corrects for these colorations. The result is a genuine improvement of the loudspeaker/earphone characteristics and thereby the sound. Dirac HD Sound is not a psychoacoustic sound effect, it is a sound correction technology tailored to a specific loudspeaker model.

How does Dirac HD Sound work?
Each speaker model, or earphone model, has been individually analyzed by the manufacturer in Dirac's analysis tool. Once an acoustical model of the speaker has been built, the advanced algorithms in the Dirac analysis tool will create a tailored digital controller that optimizes the performance of each individual speaker model. This controller is then shipped with every supported product to deliver a superior sound performance. The technology handles both the timing and amplitude aspects of the sound, or on a more technical level, the impulse response and the frequency response.

What are the benefits of Dirac HD Sound?
In short, the main benefit of Dirac HD Sound is that it improves the loudspeaker characteristics, yielding a better sound in terms of:
- Improved staging (localization of sound events)
- Better clarity and intelligibility in music and voices
- A deeper and tighter bass
- Reduced listening fatigue

This sounds very different from a sound effect!
Yes, sound effects have been used for decades and go by varying names. Most of the time they are turned off by the user, since they are just general-purpose effects that offer no improvement and often make the sound worse. It's artifical, and you hear it. Dirac HD Sound offers a true improvement, because it is tailored to a specific sound system model. Instead of different effects, we offer correction.

Who is Dirac HD Sound for?
Dirac HD Sound is for consumers that want to ensure themselves that the product they buy will include the best sound reproduction possible. For manufacturers Dirac HD Sound is a guarantee that they provide their customers with the best possible sound for their given product. Today Dirac HD Sound is used by companies such as Oppo, Ken Kreisel Professional Sound, and XTZ Audio. It can be applied to any type of system with a loudspeaker or transducer. TV:s, studio monitors, docking stations, tablets, mobile phones, earphones, etc., all benefit from this tailored optimization.
