Logitech is integrating the Fraunhofer LC3plus audio codec into its latest wireless gaming headsets to enable ultra-low latency audio, improved robustness, and consistent performance in real-time applications.
Logitech, a leading manufacturer of software-enabled hardware solutions, has selected LC3plus for two of their latest wireless gaming headsets (G522 LIGHTSPEED and Astro A20 X LIGHTSPEED). Both models integrate LIGHTSPEED wireless technology, emphasizing performance, responsiveness, and immersive gaming audio.
Why Low Latency Matters in Gaming Audio
The integration of Fraunhofer’s LC3plus into Logitech’s latest gaming headsets illustrates a broader trend: wireless audio systems are increasingly being optimized for interaction rather than passive consumption.
Latency is no longer just a technical metric – it is a core design parameter in modern wireless audio systems.
LC3plus is currently the only open-standard audio codec designed to combine ultra-low latency and high-quality audio with flexible implementation. Its openness provides manufacturers with flexibility in implementation while supporting interoperability across different system architectures.
Enabling Ultra-Low Latency Performance
LC3plus supports frame durations down to 1.25 ms, enabling end-to-end latency figures in the range of approximately 7 ms, depending on system implementation. LC3plus also supports multichannel audio configurations, which are increasingly used to enable spatial awareness in games.
Packet Loss Concealment Under Tight Latency Constraints
Gaming setups often operate in challenging RF environments, with multiple wireless devices sharing spectrum. In these conditions, packet loss and retransmissions can significantly affect perceived audio quality.
LC3plus addresses this with Advanced Packet Loss Concealment (PLC) mechanisms that aim to mask transmission errors without introducing additional delay.
“Gaming is one of the application areas where the technical strengths of LC3plus shines,” says Manfred Lutzky, Head of Audio for Communications department at Fraunhofer IIS. “Support for very small frame sizes allows system designers to reach ultra-low end-to-end delays. Combined with advanced packet loss concealment, this makes the codec well suited for demanding, latency‑sensitive wireless audio products.”
