Greetings,
I'm trying to find either a free .NET library or a command-line executable that lets me convert M4A files to either MP3s or WMA files. Please help :).
Found it!

There may be other solutions, but this is gold for what I was looking for.
P.S. I've written a .NET DLL which handles this behind-the-scenes. It's pretty terrible code, but it gets the job done.
