I would not worry too much about RMS prior to mastering - just worry about getting a good mix and controlling the peak.
I try to keep -pre-master peak at -3dB or lower. This is to "leave room" for mastering. Sometimes I will stick a hard limiter at that level to make sure I don't go over, but that's only if there are a couple little peaks here and there that are close - other than that, I just back off in the mix.
Everyone is different , but I pay very little attention to PEAK levels during recording, and about 100 times more to RMS levels whilst recording.
It would take me a zillion pages of typing to explain why but basically.....
I mix at a reference level coming out of my monitors....as I mix song to song, the same volume generally hits my ears from my monitors, this reduces the effect that volume has on percieved levels....search "Fletcher Munson"...this gives me incredible "repeatability" on my mixing.
I use a system to manage levels during tracking....search "0VU =18dB" or "K20 system Bob Katz"
Basically, I track instruments leaving a boat load of "headroom" in the digial realm. I track using the "analog" part of the chain is operating at optimum levels (I dont overload the mic, I try and put the mic in the right place,I use the preamps in their optimum position"
This allows me to get a detailed and clear sound.
I track to the K20 principle, this gives me a 20db "Crest Factor" which means I can just get on with the job of tracking, and at them end of the take, check the PEAK meter to make sure I dont have any overs, which I never do , setting stuff up like this...takes the guess work out.
When I have finished a mix, I also mix at K20, My mixes have good consistency, and go to the mastering engineer with maybe 5 or 6dB of headroom, sometimes a little more, if its say a ballad, and maybe a touch less, if the song is a bit more full on. The mastering engineer loves me...he has room to work ...8).
I spent a good year , working through all this stuff, after already being a very experience "home recordist" (say 20 years at that point) when I went to make my second self released album.....I made the point of saying to myself, I want to learn why my recordings dont sound as professional as what I hear on CD....and I worked insanely hard to get as good as I could...
Now you can listen to the song in my signature, to decide for yourself If I achieved my goal, to my mind I have, and it was worth the thousands of hours, of reading, re reading, practicing, pestering, and more and more reading.....try and look past the song, if you dont like that style of music, and listen to the engineering and such.
My RMS level when mixing is at -20db....that matters zero...really, again listen to the song in my signature, and see if you think it suffers acoustically...it has been mastered, of course, and its mastered by a professional, for good reason, I sell the CD, and I want the best for my music, after working on this album day and night for a year, I have no objectivity I couldnt master myself out of a wet paper bag....8)....
Spend your time, learning how to track and mix, and getting the best out of your voice, instrument, song arrangement, room, gear...everything ....dont worry about mastering...at this point...in fact unless you are presenting more than one tune to someone, its not really mastering in the true sense....
dont mean to come over as preachy....I just sometimes wish , I could take some of the stuff I have gone through and just place it in others hearts/heads so they wouldnt have to go thru it.....
hope it helps someone...
cheers
