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
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
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.
