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

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, […]

Bluetooth Auracast broadcast audio is the new name for Bluetooth LE audio sharing

Multi-stream and broadcast audio features part of the Bluetooth LE Audio standard have been given a brand name by the Bluetooth Special Interest Group (SIG). Meet Bluetooth Auracast broadcast audio, or simply Auracast for shorts. As a reminder, Bluetooth Audio LE broadcast enables an audio transmitter, be it a smartphone, laptop, television, or public address system to broadcast audio to an unlimited number of nearby Bluetooth audio receivers that could be speakers, earbuds, or even hearing devices. Auracast broadcast audio will let users invite others to listen to the same music without disturbing others around them, for example, a group of friends could listen to the music in the subway or on a bus through Auracast-enabled earbuds. Auracast will also be useful in public places, where for instance, users could listen to the audio from muted televisions at airports, gymnasiums, or train stations, and public announcements (e.g. gate changes, boarding […]
