Overview

This LC3 codec was designed as a low complexity communications codec within the Bluetooth LE Audio specification, to deliver high-quality speech and audio streaming, even at low data rates, overcoming essential shortcomings in today’s wireless communication platforms.
A reduction of the required bit rate by roughly 50 percent compared to the legacy SBC codec facilitates low-energy audio services – making it possible either to extend products’ battery life or to create smaller devices.
LC3 Codec Development Status
Participated in the virtual LC3 IOP of HA Working Group in June’20.
Inter-oped Fixed point implementation for ARM Cortex-Ax and –Mx processors.
One of the few companies to pass all the encoder and decoder test cases for both 10ms and 7.5ms configuration.
Objective Difference Grade (ODG) calculated using Passed Perceptual Evaluation of Audio Quality (PEAQ advanced) algorithm and passed for all reference audio tracks from the European Broadcasting Union Sound Quality Assessment Material (EBU SQAM CD).

Paving the way for the next generation audio codec for the True Wireless Stereo (TWS) applications - PART 1 : TWS challenges explained

The audio market for wireless Bluetooth headsets is growing rapidly. Audio devices using Bluetooth (BT) connectivity are more ubiquitous than ever. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. The latest trend in wireless headsets and speakers is True Wireless Stereo systems (TWS), consisting of two independent units that are each charged in their own charging case.
