How would someone go about building an audio conversion program using VB.NET 2005? Or more specifically, say I wanted to build a program that would allow the user to select a *.WMA file and convert it to a *.WAV file. From a design standpoint, thats a pretty easy setup; couple labels, a textbox and a button. But from the code aspect I'm sure there are codecs to deal with as well as some other things. Just looking for a nudge in the right direction. Any suggestions are appreciated. Thank you in advance.
