QNX has expanded its collaboration with Haleytek to enable a fully centralized software-defined audio (SDA) architecture for Volvo Cars’ upcoming EX60 electric SUV. The companies aim to support the OEM’s progress in its Superset tech stack strategy, which seeks to unify hardware and software into a scalable, future-ready platform.
The EX60 will debut with Volvo Cars’ upcoming SPA3 infotainment platform, featuring branded sound system options from multiple prominent audio providers. Unlike traditional approaches that rely on dedicated digital signal processors (DSPs) within amplifiers, SDA centralizes audio processing on a powerful system-on-chip (SoC), providing auto makers with greater flexibility, faster deployment and a foundation for continuous software innovation.
“Our Superset tech stack strategy is about building a foundation that is optimized for continuous improvement,” said Martin Kristensson, head of software defined vehicle at Volvo Cars. “Through collaboration with QNX and Haleytek, we’ve delivered a centralized audio architecture in the EX60 that enables flexibility and long-term innovation. This approach ensures we can evolve capabilities over time, providing customers with a premium experience that keeps getting better long after they drive off the lot.”
World’s first centralized SDA architecture
The centralized SDA architecture using QNX Sound was achieved through close collaboration between QNX and Haleytek, Volvo Cars’ software subsidiary, leveraging QNX Sound and the Oasis VirtIO Sound open standard.
QNX Sound is a digital audio platform for software-defined vehicles (SDVs) that decouples audio and acoustics software from hardware, unifying all vehicle audio functionalities, including voice treatment, media playback, alerts and noise control into one system.
“We are proud to collaborate with Volvo Cars and Haleytek on advancing software-defined audio in the EX60,” said Grant Courville, SVP of products and strategy at QNX. “This implementation demonstrates how QNX Sound enables auto makers to migrate more vehicle functions to software. By embracing a fully centralized SDV architecture in the EX60, Volvo Cars is reinforcing its Superset Tech Stack vision – creating a platform that supports continuous updates, scalability across models and a future-ready approach to in-vehicle experiences.”
“Delivering a centralized audio architecture in the EX60 reflects how software can unlock new possibilities,” added Erik Gustafsson, lead architect at Haleytek. “This approach gives Volvo Cars flexibility for future enhancements and demonstrates a model that can scale across programs. It’s a clear signal of where the industry is headed: toward platforms that simplify complexity and enable continuous innovation. It’s only a matter of time before other auto makers follow in the wake of Volvo’s leadership.”
