Swedish digital audio specialist Dirac has announced a collaboration with US-based semiconductor maker Analog Devices Incorporated (ADI) to deliver a new generation of entry-level in-car audio systems.

The automotive industry is increasingly prioritizing audio performance as a key differentiator in vehicle sales.

Using Dirac’s digital solution coupled to its SHARC processor line, it’s thought that ADI’s automotive customers will be able to achieve an optimised acoustic, immersive sound experience more cost-efficiently to its entry-level sound systems, typically supplied in cars, utilising up to 9 speakers.

Dirac and ADI have worked indirectly together for years, separately supplying component solutions to leading automotive manufacturers and suppliers. Through this direct collaboration the companies say they’ll be able to more effectively scale their bundled solutions to reach more customers worldwide.

Dirac’s all-new solution for entry-level systems was launched in March 2021,

Dirac’s digital solution, which will now be bundled with ADI processors, is built upon an all-in-one intelligent audio platform comprised of a measurement system, tuning tools, sound optimisation algorithms, and hardware interface platform.

The intelligent audio platform features a semi-automatic tuning system based on scientific measurements that optimizes performance and delivers signature sound in a way that is highly efficient, consistent, and predictable.

The Dirac platform also includes patented digital sound optimization and spatialization technologies that vary depending on the level of speaker system. For entry systems, the available technologies are measurement-based magnitude response correction, patented virtual bass, and virtual center, to tackle common acoustic challenges like negative car cabin impact, unbalanced soundstage, and lack of immersion. For higher range systems, Dirac offers solutions like sound stage widening and active comfort zone.

The recently released ADSP-2156x family of automotive SHARC processors is available in a range of clock speeds from 400 MHz to 1 GHz. Featuring up to 1.6 MB of on-chip SRAM, enhanced FIR/IIR hardware accelerators, and digital audio interface, the ADSP-2156x processors are specifically designed for real-time audio processing applications.
