The integration will be part of Volvo’s new SPA3 infotainment platform. Unlike legacy systems that rely on dedicated digital signal processors (DSPs) housed within physical amplifiers, the Software-Defined Audio (SDA) approach centralizes processing on a single system-on-chip (SoC). This shift allows Volvo to decouple audio and acoustics software from the vehicle's hardware, providing a more flexible foundation for high-end branded sound systems.
A Shift Toward Centralized Processing
According to BlackBerry, this centralized architecture significantly reduces complexity while accelerating the deployment of new features. By utilizing QNX Sound, the EX60 becomes the first production vehicle to leverage a fully centralized SDA environment. This allows the automaker to update audio profiles and acoustic settings via software updates without requiring hardware modifications.
HaleyTek, a joint venture between Volvo Cars and ECARX, worked alongside BlackBerry to ensure the platform supports multiple prominent audio providers. This modularity ensures that future Volvo owners can access diverse branded sound-system options through the unified SPA3 interface.
