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.
