Universal Mobile Telecommunications System (UMTS); LTE; Codec for Enhanced Voice Services (EVS); ANSI C code (fixed-point) (V13.3.0; 3GPP TS 26.442 version 13.3.0 Release 13; Includes Diskette)
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 (3GPP TS 26.445)@ Voice Activity Detection (VAD) (3GPP TS 26.451)@ Comfort Noise Generation (CNG) (3GPP TS 26.449)@ Discontinuous Transmission (DTX) (3GPP TS 26.450)@ Packet Loss Concealment (PLC) of Lost Packets (3GPP TS 26.447)@ Jitter Buffer Management (JBM) (3GPP TS 26.448)@ and AMR-WB Interoperable Function (3GPP TS 26.446). Requirements for any implementation of the EVS codec to be standard compliant are specified in 3GPP TS 26.444 (Test sequences).
