Thanks a bunch for this article, it has proven extremely helpful! The only part which I struggled with (since I’m a .net newbie) was the actual code to build the generic list for “MP3FileList”. After enough experimentation I got it to work by using logic such as:

Dim MP3FileList As New System.Collections.Generic.List(Of String)()

MP3FileList.Add( server.mappath(“/audio/file1.mp3″) )
MP3FileList.Add( server.mappath(“/audio/file2.mp3″) )

etc

Thanks again!

@theonlykenobi thanks for the comment. Unfortunately I cannot provide the full source for the page without crossing the line my employer for whom I wrote it. I have basically provided all the guts of the process here and there is very little else to do. Given the letters shown on the captcha image (presumably held in session), create a list of the letter/number mp3 files you need to join together and pass it into the concatenator. Output the returned memory stream to the response as shown.

OMG! Awesome article, just stumbled accross it.

Is this the full source of the audio implementation? If not is there any chance of providing it?

Again awesome….
