26.1733GPPANSI-C code for the Adaptive Multi-Rate - Wideband (AMR-WB) speech codecRelease 17TS

The present document contains an electronic copy of the ANSI‑C code for the Adaptive Multi-Rate Wideband codec. The ANSI‑C code is necessary for a bit exact implementation of the Adaptive Multi Rate Wideband speech transcoder (3GPP TS 26.190 [2]), Voice Activity Detection (3GPP TS 26.194 [6]), comfort noise (3GPP TS 26.192 [4]), source controlled rate operation (3GPP TS 26.193 [5]) and example solutions for substituting and muting of lost frames (3GPP TS 26.191 [3]).
