Logic playback Sounds Different From Bounced .WAV .AIFF &.MP3's

okay, ill try the not normalizing. that is like probably the one thing i havent tried.

thanks you guys. and sorry about the lack of information. but how do i say all the stuff in the 17+ hours i have put into this mastering process. lol but last night after everything failed. there is one thing about this song that is different then every other song i make and that is that i started working on this song in 9. then i got x so it transferred over. im wondering if that has anything to do with the problem. because the only thing i could think was the problem after all of this is that it must be a glitch.

So day two now of working of this. I went back into the mix thoroughly and did many things many corrected what ever compression i saw i could try and squeeze. but in the end. no matter what i bounce it never sounds like what im listening too. please someone have some valuable insight on what i should do. i feel i have literally tried everything. and inside logic the song sounds great but once i bounce it it sounds like crap.

I am bouncing as a wav mostly. but ive tried aif just about as many times as .wav. Regular format 16 bit 441100 samples or something, intervaled, normalize on and off. itunes is what im listening it back from. the thing thats wrong is that in certian parts no matter what i seem to do areas of certian instruments volumes are being taking away and others maybe added. but either way in the logic file its not there. its a full sound and its good. i have mixtered and just regular mixed. ive have a file for each that is the way i like it for either.

Well i dont think i have any "itunes enhancements" and im not clipping. at all.

What i can tell you is this. i have a guitar loop, a second and a third guitar, a horn section, drums, bass, 3 tracks of lead vocals, & a acoustic guitar. all have been compressed and EQ'd. i have buses going to all the things that are grouped. i.e. drums, vocals, guitars, ect... i have those buses compressed and EQ'd. & 2 effect buses. i have mixed it over 100 different ways(or it seems, maybe literally)

I also, want to mention this is the only song i have ever had this problem. and just last night i came to the realization that this is the only song in which i started in nine and carried over and finished in ten. Now, i really hope to christ this isnt a glitch. This is one of the best song people have said i have ever made. i would like to be able to produce this maximizing its volume. the only time i have ever been able to produce this song half right. is with it quieter than most professional music.

So that any better?

Wow. okay. you have my really stumped here. I feel dumb saying this. but im not even sure what all exactly you mean by "multi-track." it sounds important though.

And ive heard of stems before but im not sure how to produce them really, other than selecting the tracks i want to stem by solo'ing and just bouncing that. which ill be honest ive thought about doing for this.

And i want to say ive done that and tried that. the "Bounce out the best mix you can possibly achieve with headroom and bring back into logic as a stereo wav to deal with volume." but everytime i go to add volume. thats where its messes up again. and it takes volume away for certian areas where when i listen to it in logic is full and good.

OK. well. first i want to say thanks again for helping me. Second i want to say that all that output stuff was practically deleted, as you can see it was turned off. none of the plugins were a affecting my mix.

And the rest of that didnt make any sense to me

Now, lemme say how i figured it out.

the problem had nothing to do witht the stems you were right. {(probably) (im not sure because, i did happen to do the stem route, and it worked fine, probably didnt have to, but i wanted to learn how to produce a song with stems anyway.)}

So i made the stems, bounce a good mix from that. the started mastering... now heres where i think i was going wrong, i was trying to add volume in all of the wrong ways. hers the big thing i learned (DYNAMIC PLUG-INS) the one inparticular(EXPANDER) its like the opposite of compression, or thats how i like to look at it. but thats what i needed. i need to expand the way file of the mix that i liked so much. full of volume and pep, and now it sounds good.

thanks for all your help guys. i wouldnt have been able to do it will out you guys probably.

Just tried the "normalizing off" it did seem to read a little better, whats the overload protect only? would that help? i would think so. but i also dont know what its for.
