This is something that's been puzzling me for a while. We all strive to come up with systems that are capable of reproducing the low frequency effects so prevalent in movies these days. What I'm wondering is how those effects are generated/captured? It seems like it would be just as hard to create or capture those sounds as it is to reproduce them. I mean, no one was there with a wide range microphone and a superb recorder when the T-rex took that ominous step in Jurassic Park. Is it just synthesized?
