Thencheck the speech-codec sample whichreports performance in MHz per channel.Run it with appropriate files and modeson a processor of your choice andjust devidethe CPU frequency by thereported performance number in MHzto get roughnumber of realtime channels. For example, on a server with CPU 3.2 GHz andreported 24 MHzfor encode and8 MHzfor decode you may get supportedabout100 duplex channels(3200/(24+8))=100.<BR /><BR />Vyacheslav<BR />IPP speech coding Thu, 01 Jul 2010 08:22:30 GMT https://community.intel.com/t5/Intel-Integrated-Performance/GSM-UMTS-Codec-performances/m-p/788672#M2212 Vyacheslav_Baranniko 2010-07-01T08:22:30Z
