(October 1, 2020) Sweden's Dirac is in the news again, officially launching the availability of a bold new wireless headphones DSP initiative. Before today, enthusiasts could only apply digital sound optimization using an external device or a playback system. Dirac is changing that, becoming the first solution that's directly integrated onto a wireless headphone's chipset.
The company's ability to integrate and operate its solution natively is revolutionary for wireless headphones manufacturers. Dirac says it allows them to accurately fine-tune sound, while efficiently delivering consistency across various models. As for enthusiasts, they benefit from easy access to Dirac's spatial audio magic.
Spacial audio, enabled by Dirac's patent Dynamic HRTF technology, creates an immersive stereo experience from standard stereo content. It provides listeners with sound "similar to what is achievable with a home theater system" without the need for content encoded specifically for immersive playback. Further sound optimization enhancements are applied to magnitude response and impulse response, digitally correcting performance for balanced sound with fine-tuned bass output.
"While TWS earphones miniaturize, and the size of the speaker drivers are further reduced, consumers continue to expect great sound quality from these increasingly small devices," said Peter Cedmer, Director of Product Management, Headphones, Dirac. "Our solution empowers wireless headphones to stand out in a fiercely competitive market by delivering superior sound quality from smaller form factors than ever before. The speaker optimization feature can even be offered alone, without the spatial audio feature, to OEMs that focus solely on maximizing headphone sound quality."
As AV NIRVANA reported in previous months, both Klipsch and RHA have committed to incorporating Dirac's latest headphone optimization tool into wireless headphone models, and other companies will likely follow suit. Dirac says its technology works with chipsets from vendors such as Mediatek, BES, and Qualcomm, and Dirac experts will help industry partners achieve desired playback characteristics.
