Overview

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

Three Design Aspects you shouldn't miss while building an NB-IoT Protocol Stack

It is very important that the design aspects of the NB-IoT device protocol stack ensure low module cost and low energy consumption. This is required to match the industry expected module costs. This paper outlines some of the NB-IoT Protocol stack specification flexibilities and generic design aspects that are to be considered to meet the above requirements, especially with reference to LTE.
