OnePlus has officially announced that the OnePlus 6 uses Dirac sound optimization technologies, namely Dirac Power Sound and Dirac HD Sound, to boost both speaker and headphone audio quality.
Dirac is a Swedish audio firm that specializes in sound optimization and they have partnered with manufacturers like BMW, Bentley, Rolls Royce and a lot more.Some smartphone manufacturers like Xiaomi, OPPO, and Huawei have already used Dirac’s optimisation technology.
Dirac Power Sound is a technology that makes even the tiniest speakers give a full-sized audio playback experience. It cannot be switched on or off.
Dirac HD Sound is for headphones, and in this case, specifically the OnePlus headphones. The technology can best be described as a kind of equaliser that optimises the output of speakers and headphones.
OnePlus and Dirac have worked together since 2015, starting with the OnePlus 2.
According to Erik Rudolphi, Dirac’s general manager of mobile, “At the core of both of these innovative audio solutions lies our desire to eliminate the notion that mobile devices, due to their physical properties, have limits with regard to the audio quality they can deliver. Dirac Power Sound and Dirac HD Sound challenge the audio constraints inherent in these devices and offer a rich, full and premium listening experience – as evidenced in the new OnePlus 6.”
