Hi Micheal, One of way for this should be by checking the header of the file with its OggS magic number. You may take a look at this page to see if it could help ! http://en.wikipedia.org/wiki/Ogg But I'am confused that the mime type should be enough what type of data its coming ! Are there are any more things you need to concern ? Thanks, Regards, Eric, On Wed, Jan 27, 2010 at 11:23 AM, Michael A.
