So I've been reading up a little bit and I've run into a bit of confusion. I recently read about this "straight line rule" while tracking. I'm sure you all know what that entails. I think I understand this technique, however, what I don't understand is that everyone around here seems to be saying that the way to go is to track everything as hot as you can without clipping so that you have all that room to work with later on. The stuff I've been reading is saying that recording using the straight-line rule is "good engineering practice." What am I missing?
