1 Scope p. 5

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), Voice Activity Detection (TS 26.094), comfort noise (TS 26.092), source controlled rate operation (TS 26.093) and example solutions for substituting and muting of lost frames (TS 26.091).
