This TS contains an electronic copy of the ANSI C code for the GSM half rate codec. The ANSI C code is necessary for a bit exact implementation of the half rate speech transcoder (TS 06.20), Voice Activity Detector (TS 06.42), comfort noise (TS 06.22), Discontinuous Transmission (TS 06.41) and example solutions for substituting and muting of lost frames (TS 06.21).
