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.
