Hello Every Body
I am back, this time I am facing same problem. according to the formula given by DdoubleD i resolve DSS audio file duration problem, but this time some dss file is more compressed and duration of these file different according to size of file.
IS there is any technique in .net 2005 so that i can include any third party's player and find duration and other thing

I tried to include DLL of these player but not compatible with .net.
.DSS file is basically dictation by doctor(olympus recorder is use to record dictation and it save these file in .dss format)

I allready included WMP.dll for MP3. But .dss is creating problem.

Any idea or technique will be appreciable.

thanks
