Hi All - I've read any number of times that a good place for live recording mics is up in the air; "the higher the better" was indicated on more than one occasion. What characterizes the difference in sound between typical ear-level and higher up? What makes it better? I understand that this is probably a generalization and isn't always true, but it seems to be recommended most of the time. This also implies that the best sound (at least from a recording standpoint) is not where the audience is sitting, at least in most rooms.
