scope:
This annex1 specifies the digital test sequences for the adaptive multi-rate wideband (AMR-WB) speech codec specified in Rec. ITU-T G.722.2, its Annexes A and B, and its Appendix I. These sequences test for a bit-exact implementation of the adaptive multi-rate wideband speech transcoder, voice activity detection, comfort noise, and source controlled rate operation.
1 This annex includes an electronic attachment containing test sequences for the verification of the implementation of ITU-T G.722.2 AMR-WB codec.
