Logic 5.5 (PC) Clipping on Main Output BUT!

Hello. Ok so ive been running into some problems and i am trying to figure out why.
When i add some sounds and drum tracks or what not. I make sure none of the levels go over 0db. I never keep any track at 0db anyway. usually much lower. But when i look at the Output1-2. I see that it is clipping. Hitting probably 2.3db maybe more. So i try to review my audio tracks to see if anything is clipping individually, but nothing.. What can be the problem. Is it any sound that is on the same freq or something. Can that even create clipping. Why am i not able to see which sound is making the track clip like that..
If there is anyone who can help me with my problem please please please let me know..
It seems as if i keep lowering the volumes and nothing. my track ends up sounding very low when i bounce it. There are no Levels at 0db except for the Main Output 1-2 That i use..
Any input or information is much much apprecaited..
Thank you So much.. |

| Turn down main output? |

| Turn off all compression/limiting. Sometimes bad compressor settings can cause transient spikes that makes the track clip. |

Some simple maths:
Mixing is adding channel amplitudes.
Uncorrelated signals add in power domain. That is, the signal power of the mix is the sum of both input signal powers. Speaking of Levels that results in a plus of about 3dB in mixlevel if both signals have the same power.
Correlated signals add in amplitude domain. For the mix level this means a plus of 6dB for two channels of equal amplitude.
Mixing several channel at about 0dB will raise your mix-level depending on signal structure between 3dB and 6dB each time you double the number of channels.
As you do not know about the actual signal structure you should calculate with a 6dB gain as peaks will occur at that level. |

...and this might be an option, as most systems work on floats with 0dB set to +-1.0 you won't loose signal quality for the final mixdown. But remember that your signal path is expected to be in the 1.0 range so effects on the sum channel migth still distort. |

GEEEEEZZ!!!!. I am sorry Doctors, But i understand what you mean SOME WHAT!.. But not exactly
So what are you exactly trying to say. Should i just try to lower the Output 1-2 Level. Or the Master Level. I will try turning off the compressors. But i already Bounced Some of the Tracks from Midi to Audio witht Compressor on already. So what does that mean.. |

So if my main output is clipping at about +6dB, but all individual channels are not clipping at all, would it be better to turn down my main output fader or all the faders of individual tracks? (I can adjust the volume of all faders by the same amount simultaneously in Logic).
I can usually achieve no clipping on the main outputs when my kick and bass played together are peaking at about -6dB, but then some of my other channels end up in the -15dB, even -20dB zone; and I think when faders are that low it has an effect on my send effects. What do you think? |

this is whats happening to me. I end up lowering all my faders down really really low So that it wont clip and sound ok. But then it sounds to low when i bounce it. So its not sounding the way it should.. If i try to mixdown or even bounce the final mix it sounds Way lowere than any other track. It sounds like it needs a little juice. I try normalizing. and Still doesnt sound proper. So what can be the problem. Am i the only one having the problems. or is it a common thing.?
Thanks for the help in advance |

| Well, once you run your track through a good limiter it will regain the loudness. It is normally recommended to keep your peaks at around -3dB before you submit your track for mastering. But what I'm concerned about is whether I will achieve better results by lowering the master fader to prevent clipping or the volume of each individual track. Anybody? |

| Probably the Individual tracks and then you can always boost the master up after your done mixdown. So you want to try to acheive the best sound you can on your individual tracks. That way it sounds balanced before main master. |

Individual tracks should be bounced at 0dB or (-3dB to be safe) to get the most out of your bits. Boosting a bounced track with low volume will boost digital noise.
When mixing keep an eye on the sum. Don't worry about the individual channels trust your ears. If some parts are too weak compress/limit them a little to remove peaks that might clip your sum.
Boosting the master is good as long as you are in logic (no bouncing) but remember the expected input range for inserts (sends can be adjusted individually) changing the level will change the impact of dynamic effects and maybe some others. |

What I usually do is set the kick and the bass to peak around -8dB and then add the rest of the instruments. This seems to work, but some of the instruments end up pretty low in terms of volume judging by the meters; they do sound balanced compared to the rest of the mix to my ears though. So is it normal for some of the instruments to be that low?
Thanks! |
