LC3 and LC3plus: The new audio transmission standards for wireless communication

The new Low Complexity Communication Codec (LC3) and its sibling Low Complexity Communication Codec Plus (LC3plus) were developed to solve essential shortcomings present in today’s short-range wireless commu-nication platforms such as Bluetooth and Digital Enhanced Cordless Telecommunications (DECT). The codec operation modes range from medium bit rates for optimal voice transmission to high bit rates for high-resolution music streaming services. Furthermore, the codecs operate at low latency, low computational complexity, and a low memory footprint.
