A new codec for Enhanced Voice Services, the successor of the current mobile HD voice codec AMR-WB, was standardized by 3GPP in September of 2014.

This paper provides an in-depth insight into 3GPP’s rigorous and transparent processes that made it possible for the mobile industry, with its many competing players, to successfully develop and standardize a codec in an open, fair and constructive process. We also provide an overview of the EVS codec technology, the standard specifications, and the performance of the codec that will propel evolved HD voice to an unprecedented quality level.
