Home audio is evolving rapidly, and the consumer demand for immersive, cinema like sound at home is on the rise. As soundbars have become the central audio hub, adoption is still hampered by setup complexity and rigid speaker layouts. Together with StreamUnlimited , NXP addresses these constraints with a reference implementation that enables effortless setup and customized placement.
Home audio systems continue to evolve to deliver cinema-level immersion without the complexity of a traditional multicomponent setup. Soundbars—increasingly seen as the central speaker in whole home audio solutions—can now deliver the performance once reserved for professional setups and dedicated theater speakers. Connected to local sources and streaming services that feature immersive formats (Dolby Atmos®, DTS:X®, 360 Reality Audio™, MPEGH Audio™), advanced post-processing and higher channel have become the standard.
Remote speaker positioning remains one of the most challenging aspects of home audio system setup, with most designs built for fixed and ideally placed speakers. Flexible renderers, such as Dolby Atmos® FlexConnect™, allow wireless speakers to be positioned anywhere as the system adapts immersive rendering to arbitrary layouts and audience position. However, to fully unlock this flexibility, systems must know exactly where each speaker is located in the room. This is where UWB spatial ranging and sensing can be transformative. Combining UWB spatial ranging and sensing, adaptive immersive rendering and modular embedded audio platforms enable the next generation of home audio with effortless setup and complete placement freedom.
Immersive audio is no longer just about sound quality – it’s about intelligence, adaptability and removing setup friction. By working closely with NXP, we’ve built a platform that integrates precise UWB ranging, reliable wireless distribution and a production-ready software stack. For audio OEMs, this means a scalable, low-risk path to flexible remote speaker layouts and faster development of next-gen immersive products.

Working together, NXP and StreamUnlimited have created a reference implementation that enables highly scalable, easy to integrate, user friendly home audio systems featuring true placement flexibility. Centered around a soundbar platform based on the StreamUnlimited Stream1955 module and NXP Trimension® SR250 ultra-wideband (UWB) integrated circuit (IC), the reference system connects to wireless speakers (equipped with Trimension SR150 UWB Solution) which can be placed freely within the room, eliminating predefined layout constraints.
What makes UWB so compelling for immersive audio is the combination of precise ranging and radar-based sensing. This spatial awareness allows systems to continuously adapt to real world environments and user behaviour. Paired with technologies like Dolby Atmos FlexConnect, UWB helps create a uniquely responsive listening experience that differentiates next generation home audio products.

NXP’s industrial and IoT UWB portfolio brings precise, reliable spatial awareness to modern smart home and audio solutions. The Trimension SR250 combines secure UWB ranging with built-in sensing, allowing devices to detect presence, movement and exact location in a room. The Trimension SR150 focuses on accurate ranging and positioning, measuring distances within a few centimeters and determining direction, making it ideal for devices that need simple but highly reliable location tracking. Together, they enable flexible speaker placement and smarter, more responsive home experiences.
In home audio systems UWB radar technology enables the best placement of speakers by accurately tracking the listener’s position to create the perfect acoustic sweet spot.
The joint StreamUnlimited–NXP reference implementation highlights how UWB spatial ranging and sensing, adaptive immersive rendering and modular embedded platforms work together to enhance accessibility for immersive audio solutions. With automatic, centimeter-accurate speaker mapping and flexible wireless placement, this approach significantly streamlines the setup process and paves the way for scalable, next-generation home audio products.
