Description and Features
The LC3plus audio codec is a highly optimized and highly efficient audio codec introduced for Bluetooth LE Audio, DECT and VoIP that dramatically improves streaming audio quality, reduces power, improves bandwidth and delivers ultra-low latency down to 5ms. The LC3plus audio codec has also received the Hi-Res Audio Wireless certification logo issued by the Japan Audio Society (JAS) for its ability to reproduce 40KHz frequencies when running at 96KHz with 24bit samples.
Our LC3plus and LC3 audio codecs are fixed point production proven implementations supporting all mandatory and optional features, highly optimized for ARM, RISC-V, Cadence HI-FI & Qualcomm Kalimba DSPs and can be ported to other DSPs or CPUs on request.
