Описание
The present document specifies the digital test sequences for the GSM adaptive multi-rate (AMR) speech codec. These sequences test for a bit exact implementation of the adaptive multi-rate speech transcoder (GSM 06.90 [4]), Voice Activity Detection (GSM 06.94 [8]), comfort noise (GSM 06.92 [6]), and the discontinous transmission (GSM 06.93 [7]).
