Look, I don't need an argument, I need answers and or suggestions.  I did
not realize until the last few days that there were so many aac libs out
there and that they can be quite different in quality. 
Again, anybody on this list that can recommend good reading material
regarding this. I've been in web dev for 9 years so I'm not ascared.
