By leveraging key technologies, Dirac Opteo and Dirac Virtuo, now compatible with NXP’s SAF4000 radio and audio solutions and i.MX 8 series applications processors, can help manufacturers to deliver optimized acoustic performance and immersive sound experiences – all without any expensive hardware upgrades. The two solutions are built upon an all-in-one intelligent audio platform consisting of a measurement system, tuning tools, sound optimization algorithms, and a hardware interface platform that – together – enables manufacturers to achieve perfected sound faster, more easily, and consistently across vehicle models.
The integration, originally revealed at CES 2023, enables automotive audio designers and engineering services to more effectively scale their bundled solution to reach more automakers worldwide.
"Premium in-car audio is increasingly in demand – no longer just in high-end luxury vehicles but in all vehicles, across all makes, models, and classes," states Lars Carlsson, Dirac’s Vice President and Head of Business Development Automotive Audio. "Dirac Opteo and Dirac Virtuo meet this demand with solutions that leverage our 20+ years of experience in the high-end market that is now tailored for entry-level sound systems. Continued collaboration with NXP, a world leader in secure connectivity solutions for embedded applications, helps us deliver on our mission to bring our renowned audio innovations from the few to the many by equipping entry-level systems with optimized audio experiences."
Dirac Opteo and Dirac Virtuo include patented digital sound optimization and spatialization technologies, including measurement-based magnitude response correction, virtual bass, and virtual center – to tackle common acoustic challenges like negative car cabin impact, unbalanced soundstage, and lack of immersion.
The intelligent audio platform features the industry’s first 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.
"Our automotive customers are increasingly seeking ways to differentiate their vehicles through premium, high-quality audio as in-car infotainment becomes a major priority for both drivers and passengers alike. At the same time, design simplification and BoM cost saving are of highest priority," states Lars Boysen, Senior Director Product Marketing at NXP. "Our expanded collaboration with Dirac to offer Dirac Opteo and Dirac Virtuo on our SAF4000 high-performance radio & audio IC allows us to reach more automakers with a joint solution that equips any car, regardless of its class or speaker system, with a hugely impressive audio experience."
The SAF4000 utilizes a state-of-the-art audio DSP processing core together with a fully integrated software defined wideband radio solution capable of covering all global broadcast audio standards, including AM/FM, DAB(+), DRM(+) and HD-Radio. The SAF4000 simplifies the development of high-performance infotainment platforms as it replaces today’s multi-chip solution with a single ultra-compact RFCMOS device combining radio and audio IC as one high-performance system solution.
Dirac is headquartered in Uppsala, Sweden, with R&D facilities in Copenhagen, Denmark and Bangalore, India, and representation in Greater China, Germany, Japan, Korea, and USA. Dirac’s automotive audio solutions are currently used by leading automotive brands Rolls Royce, Volvo, Polestar, BMW, NIO, and BYD, amongst many others.
