Is the sound on atom bomb videos real?

Like many of you I enjoy watching atom bomb videos on YouTube.  However one thing strikes me as unreal: the sound.  Usually the sound of the explosion is shown at the same time of the blast.  However, the recordings are made from miles away, which lead me to believe that they are edited.  I wonder: are these sound recordings even real or manufactured?  Can someone point me to a real video recording with a true sound of an atomic blast?

Yeah, that sucks. The sound is usually real, but the timing is adjusted for some inane reason. Before people started doing this on Youtube, one of the best things about seeing a nuclear blast in a movie or on tv was waiting for the sound, because it was stock footage and you always knew it was going to take a few seconds for the sound to arrive, thus illustrating the power of the bomb even further. This was back before the 1990s.
