This dual-mode platform with Bluetooth 5.4 functionality integrates the best of LE Audio and classic Bluetooth to support smooth feature adoption of LE Audio for real-world scenarios.  The Qualcomm S5 Gen 2 Sound Platform chips enable support for LE Audio and the Auracast™ broadcast audio capability, Unicast Voice, Unicast Music and Gaming. For earbuds, there is support for Auracast™ Broadcast audio. Auracast™ will also enable locations to broadcast Bluetooth audio to enhance the visitor experience, for example tuning into a shared TV in an airport, bar, or gymnasium.

With Snapdragon Sound, the Qualcomm S5 Gen 2 Sound Platform supports lossless audio with enhanced robustness and quality at up to 48KHz sample rate. The gaming mode offers lower end to end latency at 48ms for smartphone users, including a voice back-channel for in-game chat. Designed to bring the best experience possible for hands free calling, these platforms also support 32kHz super wideband voice calls for crystal clear calls, with Qualcomm® aptX Voice technology, and up to 3-microphone Qualcomm® cVc™ Echo Cancelling and Noise Suppression (ECNS).

This solution is designed to optimize round trip latency between smartphone and earbuds to a more natural and immersive spatial audio experience. On the phone, the spatialization and stereo rotation is supported by Snapdragon 8 Gen 2, and on the earbud side the QCC5181 delivers earbud to earbud cross head rotation alignment, low power consumption for the earbuds for longer periods of wear, optimised latency for a lag free experience and our own proprietary head orientation algorithm. 

The Qualcomm S5 Gen 2 Sound Platform supports 3rd generation Qualcomm® Hybrid Adaptive Active Noise Cancellation (ANC), which improves the listener experience by providing increased precision and noise cancelling depth, solving commonly faced issues such as wind noise or howling, with fast and reliable detection.  The SoC provides a natural full band Transparency mode (sampled at 64KHz), with effective occlusion mitigation delivering an instinctive and reliable talking experience. This great experience during conversations is enhanced by the SoC’s automatic speech detection. The Qualcomm S5 Gen 2 Sound Platform also supports adaptive Transparency modes, offering smooth transitions between immersive noise cancelling and natural sounding pass-through when a listener needs to hear the world around them. It also brings adaptive noise cancelling to earbuds, with its low power, wireless tuning.
