Find Play length of DSS Audio File...

Hi !

I know this is a very very old post, but it's well referenced in google. So I publish my solution.

Just make some reverse engineering on the DSS and DS2 file format for extract the information like this :

public static TimeSpan GetDssDuration(string fileName)
 {
     const int durationOffset = 62;
     const int durationLength = 6;
     const int headerLength = durationOffset + durationLength;

     using (var fileStream = File.OpenRead(fileName))
     {
         var fileHeader = new byte[headerLength + 1];
         fileStream.Read(fileHeader, 0, headerLength);

         var hoursData = new byte[2];
         var minutesData = new byte[2];
         var secondsData = new byte[2];

         Array.Copy(fileHeader, durationOffset, hoursData, 0, 2);
         Array.Copy(fileHeader, durationOffset + 2, minutesData, 0, 2);
         Array.Copy(fileHeader, durationOffset + 4, secondsData, 0, 2);

         return new TimeSpan(int.Parse(Encoding.ASCII.GetString(hoursData)), int.Parse(Encoding.ASCII.GetString(minutesData)), int.Parse(Encoding.ASCII.GetString(secondsData)));
     }
}

I hope this will help someone.
