Im learning what all this means but I had a quick question concerning my mix. OK, I have a mix I'm pretty happy with. I know I'm supposed to leave some headroom. I'm using reaper and on the leval meters, the main one is peak and I'm pretty sure the two on the outside of it is rms (they go up and down in a slower, more steady way). Now, as far as peak, nothing is going passes - 6 to - 12 db. However, on some parts the rms is touching red (-6 I think). I can tell it's when the bass and kick hit. Is this bad? Where should overall loudness be for a final mix, before mastering?
