26.0733GPPANSI-C code for the Adaptive Multi Rate (AMR) speech codecRelease 17TS

The present document contains an electronic copy of the ANSI‑C code for the Adaptive Multi-Rate codec. The ANSI‑C code is necessary for a bit exact implementation of the Adaptive Multi Rate speech transcoder (TS 26.090 [2]), Voice Activity Detection (TS 26.094 [6]), comfort noise (TS 26.092 [4]), source controlled rate operation (TS 26.093 [5]) and example solutions for substituting and muting of lost frames (TS 26.091 [3]).
