I recently finished a project and am now in the stages of mixing down all the tracks. I'm currently mixing in Reaper. I have a basic (and limited unfortunately) knowledge of mixing and know nothing of mastering which is why I'll be seeking professional services for that phase. I do know that most MEs like to have the mix peaking no higher than -3dbs.
My question is, if I get to a point where I'm really happy with my mix and the master is in the red, say +2 or +3 dbs, can I just drop every track in the mix say -4 db (or until I hit -3dbs on the master)? I should also note that none of the stems I'm mixing are clipping. Logically this makes sense to me, but like I said, I have a basic knowledge of mixing.
