Getting Audio File Length in C#

Expand Post »
Hi All

I am looking to be able to get the length of any audio file in seconds. Formats are WAV, MP3 and DSS. Is there anything like this...
C# Syntax (Toggle Plain Text)
  1.  
  2. int seconds = myFile.AudioLength();

Any help would be appreciated

Re: Getting Audio File Length in C#

Hey hi !

I'm trying to do the same thing to try to see the lenght of an audio file. Did you ever knew how to do it. All I know is how to get the bytes size of the file but don't know how to get the time thanks.

Re: Getting Audio File Length in C#
well, I don't remember the exact details, but maybe you can use windows properties for this?
I know there is a way to access the properties of a file under windows. If you were to access the time detail form the soundfile... that might work. Not sure if it would help for .dss files since I'm not sure windows will know what to do with those.

Hope this helps at least a little.

Re: Getting Audio File Length in C#
I saw on this calculation on the web, but I don't have a .dss file to test it with...

C# Syntax (Toggle Plain Text)
  1.         public static long GetDSSDuration(string fileName)
  2.         {
  3.             FileInfo fi = new FileInfo(fileName);
  4.             long size = fi.Length;
  5.  
  6.             long length = (long)(((size * 1.1869) - ((size / 1054) * 210)) / 1054);
  7.  
  8.             if (length > 1000)
  9.             {
  10.                 length = (long)(length * (0.61 + ((length / 100) * 0.0005)));
  11.             }
  12.             else
  13.             {
  14.                 length = (long)(length * (0.61 + ((length / 100) * 0.0015)));
  15.             }
  16.  
  17.             return length;
  18.         }

Re: Getting Audio File Length in C#
Assuming that the formula outputs time in seconds, all you would have to do is put "length = length / 60;" just before "return length" and that should work fine. (his/her solution is far better then mine since it actually calculates the value for the audiofile, I don't think windows recognizes .dss files, so it won't have any detailed info on it either)

Re: Getting Audio File Length in C#
How many seconds duration is the dss file(s) that is off by 10 - 30 seconds? Also, do you have many dss files of varying durations? If you do, and the calculation varies proportionately to an increase in duration, you could adjust the calculation to accommodate a better approximation.

EDIT: Also, be sure you are not truncating/rounding the time when calculating minutes in the divide by 60 division...
