Universal Mobile Telecommunications System (UMTS); LTE; Codec for Enhanced Voice Services (EVS); ANSI C code (floating-point) (3GPP TS 26.443 version 14.1.0 Release 14)

Scope

The present document contains an electronic copy of the ANSI C floating-point code for the Enhanced Voice Services
(EVS) Codec. This ANSI C code is the unique alternative reference specification besides the ANSI-C fixed-point code
for the EVS Codec (3GPP TS 26.442) for a standard compliant 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).
