What equipment is used for movie audio? I am looking to do sound for a documentary where we have to walk around. A computer seems like a horrible idea. Actually, anything that needs to be plugged in seems like it could be a problem. I was watching things like Metallica's Some Kind of Monster and CourtTV shows. They seem to use boom mics that go into some pouch wore around the waist of the guy holding the mic. I don't really know.
