Wired for Intelligence: SWI3S—The New Interface Standard for Ambient AI
As voice becomes the natural interface for AI systems, especially in wearables and edge devices, the limitations of legacy audio protocols like PDM are increasingly exposed. These older standards lack the scalability, synchronization, and embedded control required for intelligent, multi-microphone architectures.
Enter SoundWire-I3S (SWI3S)—the next-generation interface standard designed to meet the demands of ambient AI. With support for up to 12 peripherals on a single 2-wire bus, dynamic scheduling, and integrated control signaling, SWI3S enables compact, power-efficient microphone arrays that are purpose-built for voice-first interaction.
This talk will explore how SWI3S is already unlocking new possibilities in smart glasses, where products like Meta Ray-Ban and Oakley frames integrate 5+ microphones per unit. These wearables represent a shift toward seamless, conversational AI—where synchronized audio capture and reduced wiring complexity are no longer optional, but foundational.
By aligning MEMS innovation with the rise of ambient intelligence, SWI3S is not just a technical upgrade—it’s the new interface standard for AI communication.

Infineon Technologies AG
Dr. Gunar Lorenz is heading the technical marketing and application engineering for consumer sensors at Infineon Technologies. Gunar joined Infineon in 2016 as system project manager responsible for Infineon’s first open market MEMS microphone. Prior joining to Infineon he worked as director of system-level simulation at Coventor, where he and his group invented and developed Coventor’s MEMS/IC co-simulation design environment MEMS+. The original ideas for MEMS+ are embodied in his PhD carried out at Robert Bosch R&D Center in 1999. Gunar graduated in mechanical engineering at the TU Braunschweig in Germany and received his PHD in electrical engineering from the TU Bremen in 1999.
