Intended to work with NXP’s SAF4000 multi-standard software-defined radio ICs, a system will also typically have an i.MX 8 series applications processor, said Dirac, adding: “Through this collaboration, automakers can now digitally upgrade the performance of entry-level sound systems, which are typically those supplied in cars utilising up to nine speakers.”

 

Opteo and Virtuo are the names of Dirac’s products, which include sound optimisation including measurement-based magnitude response correction, virtual bass and ‘virtual centre’ “to tackle common acoustic challenges like negative car cabin impact, unbalanced sound-stage and lack of immersion,” it said.

 

SAF4000 includes DSP and covers broadcast audio standards including AM, FM, DAB(+), DRM(+) and HD-Radio.

 

Dirac‘s products are designed into cars from Rolls Royce, Volvo, Polestar, BMW, NIO, and BYD. Find te company at CES in the West Hall of the Las Vegas Convention Center, booth 6677.
