ETSI ETSI TR 126 952 V14.0.0 (2017-04)73GPP TR 26.952 version 14.0.0 Release 141 Scope The present document provides information on the Enhanced Voice Services (EVS) codec Selection, Verification and Characterization Phases which were run using the fix
33、ed-point code (3GPP TS 26.442). Experimental test results from the subjective quality testing are reported to illustrate the behaviour of the EVS codec. Additional information is provided on implementation complexity of the EVS codec and objective test results. Also the verification results for the
34、floating-point version of the EVS codec (3GPP TS 26.443) are presented. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, v
