What do you mean no audio was captured? There are dozens of films with audio. And the planes were CGI? You mean in this film or in ALL of them as part of your big conspiracy? Despite the many thousands of witnesses in NY who saw them? And that building is obviously in front of the towers. If it was behind them it would have to be nearly as tall as the towers themselves. Seriously catatonicclam, are you joking or are you really that stupid?
