ETSI ETSI TR 126 976 V13.0.0 (2016-01)73GPP TR 26.976 version 13.0.0 Release 131 Scope The present document provides information of the AMR Wideband (AMR-WB) Characterisation, Verification and Selection Phases. Experimental test results from the speech quality related test

33、ing are reported to illustrate the behaviour of the AMR-WB codec. Additional information is provided, e.g., on implementation complexity of the AMR-WB codec. Also the verification results for the floating-point version of the AMR-WB codec (3GPP TS 26.204) are presented. 2 References The following do
