    what all audio formats you support? – ajay_whiz Apr 19 '11 at 10:14

You could use the NAudio library as suggested in this answer to a similar SO question.

We can do it easily by given below code 

private string GetDuration(string FileFullPath) 
{ 
string duration = ""; 
string fName = FileFullPath.Substring(FileFullPath.LastIndexOf("\\") + 1); 
string filePath = FileFullPath.Substring(0, FileFullPath.LastIndexOf("\\")); 
Shell32.Shell shell = new Shell32.ShellClass(); 
Shell32.Folder folder = shell.NameSpace(filePath); 
Shell32.FolderItem folderItem = folder.ParseName(fName); 
if (folderItem != null) 
{ 
duration = folder.GetDetailsOf(folderItem, 21); 
} 
folderItem = null; 
folder = null; 
shell = null; 
return duration; 
}

You may look at taglib#

TimeSpan span= GetWavFileDuration(filePath + "\" + fileName);
string spanSeconds = span.TotalSeconds.ToString(); string[] spanSecondsArray=spanSeconds.Split('.'); spanSeconds = spanSecondsArray[0].ToString();

public static TimeSpan GetWavFileDuration(string fileName) { WaveFileReader wf = new WaveFileReader(fileName);
return wf.TotalTime; }

You can use this library for getting the Audio file duration

I would have expected that you can calculate this from the bit rate and the file length: (file.lenghtInBits / kbsp ) / 60 = minutes.

rather assumes that you can get the bit rate from the file header though.

You will need to reference Windows Media Player. Go to Com Add-ins to add the wmp.dll to your project. 

string Duration = null;
WMPLib.WindowsMediaPlayer w = new WMPLib.WindowsMediaPlayer();
WMPLib.IWMPMedia mediaFile = w.newMedia(Filename);
if (mediaFile != null) {
   Duration = mediaFile.durationString;
}
w.close();

  • it will work on your client but always returns a duration of 0 for .avi and .wav files on windows server. – Hossein Mar 02 '12 at 11:57
