26.4453GPPCodec for Enhanced Voice Services (EVS)Detailed algorithmic descriptionRelease 15TS

The description of the encoder is as follows. First, common pre-processing is described, and then the different elements of the encoder are described one by one. The discontinuous transmission (DTX) operation and the AMR-WB interoperable option are then given in separate subclauses, again referencing the same processing as in the default option.
