Qualcomm S3 Gen 2 Sound Platform supports LE Audio and Auracast broadcast audio

Qualcomm S3 Gen 2 Sound Platform

The Qualcomm S3 Gen 2 Sound Platform (QCC5181) is a Bluetooth 5.4 audio solution designed for dongles and adapters with ultra-low latency (<20 ms) and support for the latest LE Audio and Auracast broadcast audio standards. The platform was introduced last year, but the company says it has now launched a “newly enhanced solution” optimized for gaming that “combines Snapdragon Sound and LE Audio to deliver ultra-low latency of less than 20ms for lag-free wireless audio with voice back-channel for in-game chat”. The new solution also focuses on USB dongles and adapters since few hosts support Bluetooth 5.4 at this time. Qualcomm S3 Gen 2 (QCC5181) Sound Platform specifications: CPU – Dual-core 32-bit microcontroller clocked at up to 80 MHz DSP – Qualcomm Kalimba DSP @ 240 MHz with 384 kB program RAM, 1,024kB data RAM Storage – External QSPI flash  Connectivity Bluetooth 5.4 qualified Bluetooth Low Energy, Bluetooth Classic, […]
