Fraunhofer IIS and Airoha Demonstrate LC3plus-Based Multichannel Spatial Audio on AB1595 Bluetooth SoC at MWC 2026

Airoha, by contrast, frames the same system through a silicon and scheduling lens. The AB1595’s heterogeneous compute layout suggests a conscious separation between control, audio DSP, and hardware acceleration, allowing spatial rendering, sensor fusion, and transport to coexist without fighting for cycles. This is where the dual HiFi5 DSPs and AiroHAP block matter more than headline specs: they enable deterministic latency paths, something audiophiles tend to notice immediately as “tight” or “loose” imaging in wireless setups. Support for forthcoming high-throughput Bluetooth profiles also hints at a strategy aimed at future-proofing premium headsets rather than chasing current smartphone limitations.

The spatial layer itself sits at the intersection of both philosophies. Cingo’s binaural renderer is designed to be computationally frugal, which aligns neatly with Airoha’s low-power goals, but the real differentiator is how head-tracking is treated as part of the audio pipeline rather than an accessory feature. CyweeMotion’s synchronized IMU handling suggests an awareness that even micro-jitter between ears can collapse a soundstage. Taken together, the platform feels less like a flashy MWC prototype and more like a reference blueprint for manufacturers who want multichannel wireless audio to sound composed, not congested, when pushed beyond stereo comfort zones.
