Dirac Introduces Spatial Audio Solution for Direct Chipset Integration Into Next-Generation Wireless Headphones

Swedish digital audio pioneer Dirac announced that its latest spatial audio solution, which leverages the company's patented Dynamic HRTF technology, is now available for direct integration into the digital signal processors (DSP) of Bluetooth wireless headphones. The solution is now compatible with chipsets from Qualcomm, BES, and MediaTek and allows headphone manufacturers to deliver spatial audio to consumers, independent of playback devices or media players.

CEVA and VisiSonics, a developer of patented 3D spatial audio technologies, announced that the companies have collaborated closely together to develop a comprehensive 3D spatial audio solution for embedded devices, including true wireless audio (TWS) earbuds, headphones and other hearables. The collaboration combines VisiSonics' RealSpace 3D audio software optimized for CEVA’s low power audio and sensor hub DSPs together with CEVA’s MotionEngine head tracking algorithms running on its BNO080 9-axis System in Package (SiP).

In the wake of the acquisition of the Hillcrest Laboratories (Hillcrest Labs) business from InterDigital in mid-2019, CEVA now introduced the Hillcrest Labs MotionEngine Hear, a sensor and processor agnostic embedded software solution for hearable devices. The new solution allows SoC vendors, OEMs and ODMs to take advantage of a configurable sensor fusion platform to add intuitive user interface, gesture control, activity tracking and spatial audio capabilities to hearable devices.
