Software-defined vehicles are transforming automotive audio by demanding scalable and reusable architectures across increasingly complex platforms. Building a solid foundation requires mastering low-latency signal paths, early audio, multicore partitioning, thread management, and safety compliance, alongside preset management, OTA updates, HLOS control, and diagnostics. A modular "Subcanvas" approach completes the framework by organizing features, protecting IP, enabling PC-based simulation and earlier real-world integration, simplifying collaboration, and creating new opportunities for IP evaluation and modern sourcing decisions
