Packetcraft LC3

Optimized, high performance Bluetooth LC3 solution designed for low power embedded Bluetooth LE Audio products, with optional LC3plus support.

Bluetooth LE Audio introduces a new codec, called LC3, that dramatically improves audio quality, reduces power, and improves latency compared to Bluetooth Classic Audio.
