UPPSALA, Sweden, December 13, 2012 /PRNewswire/ --

Dirac Research announces the introduction of a new smartphone with Dirac HD Sound optimization built in. At the OPPO Find 5 launch event held in Beijing's 798 Art District on Wednesday, in front of over 500 members of the international press, Dirac's CEO spoke of the high-class sound quality obtained through the use of innovative sound processing.

OPPO yesterday announced the launch of their flagship smartphone Find 5. Dirac's CEO Dr. Mathias Johansson was a guest speaker at the event. In his speech, he emphasized Dirac's approach to sound technology as distinct from conventional sound technologies: "Different from sound effects, we are actually restoring the music as it was intended by the artist."

The event also featured a large-scale demonstration of a Dirac-optimized cinema theater sound system, where the audience emphatically noticed the difference when Dirac's optimization was turned off.

The technology used in the OPPO Find 5 - Dirac HD Sound® - optimizes the acoustic properties of the earphones shipped with the new mobile phones for the best possible mobile music experience. Precise acoustic measurements of the earphone have allowed a tailored digital sound processor to improve the acoustic properties of the earphone. Technologies from Dirac are also used in high-performance HiFi, luxury cars, digital cinemas and studios.

Dirac HD Sound removes the sound defects introduced by the earphone itself due to its physical constraints. The result is a clear and natural sound for music playback, a philosophy that OPPO has embraced. The technology is unique in that it corrects both the amplitude and the timing of each tone reproduced by the earphone. Dirac HD Sound has stirred a lot of reactions and comments on Internet forums, as it allows an earphone to perform at altogether new levels.

Mr. Ken Kreisel, one of the founders of M&K Speaker, known for high-end studio monitor speaker systems, listened to the sound of the OPPO mobile phone and earphone. He stated: "While listening to the new OPPO Mobile Phone with Dirac HD Sound, the sound improvement is tremendous and I feel almost like I am in the recording studio with my new studio monitors. I applaud OPPO for their innovative and pioneering spirit in embracing this new Dirac HD Sound technology."
