Fraunhofer IIS and Airoha’s Multi-Channel Spatial Audio Showcase at MWC 2026

At the Mobile World Congress (MWC) 2026 in Barcelona, Fraunhofer IIS and Airoha Technology made headlines by presenting their latest innovation in audio technology—a multi-channel spatial audio solution tailored for next-generation wireless headsets. This collaboration features the integration of Fraunhofer’s state-of-the-art LC3plus codec alongside Cingo's advanced spatial audio rendering, working synergistically with Airoha's flagship Bluetooth system-on-chip (SoC), the AB1595.

Revolutionizing Wireless Audio Experience

The core of this collaboration lies in the ability to deliver a seamless, high-definition multi-channel audio experience designed for modern mobile devices and extended reality (XR) applications. As mobile technology continues to evolve, so too do the expectations for audio quality. By employing Airoha's High Data-rate Technology (HDT), the AB1595 is equipped to maintain high audio resolution at efficient bit rates while minimizing latency, paving the way for scalable multi-channel headset designs that transcend the limitations of traditional stereo audio.

Cingo's Binaural Rendering and 3D Audio Experience

Central to the user experience is Fraunhofer's Cingo binaural rendering technology. Cingo transforms multi-channel audio content into an incredibly immersive 3D sound experience directly on the headset itself. This innovation is pivotal for applications in streaming, interactive gaming, and immersive communication, ensuring a lifelike auditory experience that adapts to the surrounding environment. Cingo stands out by providing excellent sound fidelity while keeping energy consumption low—an essential factor for mobile and wearables.

Enhanced Tracking with CyweeMotion

The integration of CyweeMotion sensor technology introduces dynamic spatial audio with head-tracking capabilities, enabling extraordinary user engagement in immersive media experiences. By utilizing single and synchronized dual-ear inertial measurement unit (IMU) sensor modes, CyweeMotion guarantees precise and responsive head-tracking performance across different design formats, whether they are true wireless stereo (TWS) or other wearable forms.

Empowering Developers and OEMs

Moreover, the AB1595 offers a developer-friendly DSP platform, allowing third-party algorithms—including those from Fraunhofer—to run smoothly and efficiently. This aspect reinforces Airoha’s commitment to empowering original equipment manufacturers (OEMs) in creating unique value propositions in an increasingly competitive market.

Yuchuan Yang, Senior VP at Airoha Technology, expressed, "We are focused on providing a robust framework that encourages our partners to expand wireless audio's frontiers. The AB1595 platform is designed for smooth assimilation of sophisticated algorithms, including our collaboration with Fraunhofer, to create bespoke multi-channel audio experiences for the next generation of connected devices."

Reliable Performance in Challenging Environments

One of the critical challenges of wireless audio is ensuring reliable performance in environments with dense radio frequency (RF) activity, such as urban areas or bustling tech exhibitions. To address this, the partnership incorporates Fraunhofer’s LC3plus Advanced Packet Loss Concealment (PLC) technology. This enhancement preserves audio streaming integrity and continuity, optimized for modern mobile networks, ensuring a high-throughput audio experience even under challenging conditions.

Experience MWC 2026 Demonstration

Attendees at MWC Barcelona 2026 had the opportunity to experience this cutting-edge audio technology first-hand at Booth #CS64. The demonstration includes:

• - High-fidelity multi-channel wireless transmission powered by the LC3plus codec.
• - Immersive Cingo spatial audio rendering with head-tracking functionality.
• - Real-time examples showcasing resilience to packet loss and low-latency performance.
• - Integration with the Airoha AB1595 SoC SDK, demonstrating the potential for developers and manufacturers to build on this platform.

With these developments, Fraunhofer IIS and Airoha are not only setting a new standard in wireless audio but also offering a glimpse into the future of immersive audio experiences. As they continue to innovate, the industry eagerly awaits the next chapter in audio technology.
