This TS contains an electronic copy of the ANSI C code for the GSM Enhanced Full Rate codec. The ANSI C code is necessary for a bit exact implementation of the Enhanced Full Rate speech transcoder (TS 06.60), Voice Activity Detection (TS 06.82), comfort noise (TS 06.62), Discontinuous Transmission (TS 06.81) and example solutions for substituting and muting of lost frames (TS 06.61).
