Rapporteur:  Mr. Varga, Imre

The present document provides information on the Enhanced Voice Services (EVS) codec Selection, Verification and Characterization Phases which were run using the fixed-point code (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 floating-point version of the EVS codec (TS 26.443) are presented.
