Been cruising several sites and reading a lot discussion regarding keeping levels significantly below 0db to the tune of -15db peak verses something along the lines of -3db which is what I would have expected to be the norm. Is this relating to Input levels? Playback levels? Output bus level? The idea is that higher levels introduce any number of issues. Can any one elaborate? Related question, what about sound of in the box mixing vs outside the box? A lot of chatter claiming ITB mixing is sterile, small, and on and on. I'm having a tough time with this one but would be interested everyone's views.
