The present document contains an electronic copy of the ANSI C code for the Enhanced Voice Services (EVS) Codec. The ANSI C code is necessary for a bit exact implementation of the EVS Codec (TS 26.445), Voice Activity Detection (VAD) (TS 26.451), Comfort Noise Generation (CNG) (TS 26.449), Discontinuous Transmission (DTX) (TS 26.450), Packet Loss Concealment (PLC) of Lost Packets (TS 26.447), Jitter Buffer Management (JBM) (TS 26.448), and AMR-WB Interoperable Function (TS 26.446). Requirements for any implementation of the EVS codec to be standard compliant are specified in TS 26.444 (Test sequences).
