That all depends. Mostly on phase (not explaining this here, google is the key). Either they will partially cancel each other, or they will add up. The first case will be pretty obvious, as you will seem to lose something. The second case is harder to spot for novices. You'll simply notice that your meters seem to peak much faster in the red, without actually providing you with more volume. That's one of the main reasons a lot of people talk about "cleaning up your instruments with the EQ". You might not hear some frequencies very well, but they still are there and can be taken in account in the overall mix (lots of small additions from residual "crap" of several instruments will still add up to an annoying amount). Then better clean them out.

I understand there are 3 stages... the first (creation) is obvious, the second (mixing) is physical automation of parameters like panning, volume fades, and FX before you convert to wav format or whatever. THE THIRD stage (MASTERING) is done how? In wav format? |
As obvious as the answer will seem : there is no magical formula. It all depends on how you constructed/recorded the sounds, and how you want it to sound in the end.
I've seen tracks where the drum instruments and bassline were compressed individually, then mixed into a group, which was compressed again. And finally the whole mix had another compression applied again. If your mix needs that, it can work. On the other hand I've heard tracks where the only thing that was done was volume balancing and nothing else, and it sounded great also. Experimentation and practice are the key words here.
I recommend that you take a day off, just using a compressor. I don't think you record with mics yet, so you can skip that stage. But use an individual instrument (like a kick or bassline for example). Use a compressor on it and spend your time fooling around. And listen. That's the most important part : listening what it does. Like I said in a previous post already, you have no idea how many people can't use a compressor (they read in a magazine that a good compression for drums might be treshold -20 dB, ratio 5:1 with an attack of 10 ms and a release of 5 ms, and they use that setting. Wrong. The first parameter to get right is the threshold. That setting is dependant on the level you recorded/used your sounds. The ratio will define how hard you will compress, and the attack/release time will define the shape of the sound, which will be unique for each sample). Figure out what each control does, and more importantly how it changes your sound if you tweak this or that parameter. Once you are familiar with that, do the same, but with the compressor inserted on a complete mix (for practice, it doesn't really matter if it's your own, or a commercial mix). Notice that it will react differently (on a complete mix, the compressor will be triggered by the loudest sound, but compress everything). Figure it out also.
-edit- another thing. The usual way to compress something is before the EQ. Experiment with the opposite too, the EQ before the compressor. Completely different reaction. Figure that out to. Once you know how stuff reacts, it's much easier for you to decide what you need to make things like you want.
About the three stages, and mostly for eq/compression :
The actual creative process, or the recording process if you're using accoustic stuff too : that's the part where you create the sounds. You'll either define this by tweaking the synth/sampler parameters. When you record with mics, the placement of the mics is the most important aspect (and the recording room accoustics of course). But it's happening a lot that a little corrective/steering EQ is already applied there (so you record a signal that is already eq'ed). The compressor in this stage is usually used to tame rogue levels, not to massively alter the sound.
The mixing stage : that's where you'll slap everything together. This includes balancing the levels, panning, effects, and the movement/automation of all this stuff too. Actually this stage has to be seen as a creative process also. It's here you'll define the movement in the song, depth, the macrodynamics, (will you mix the choruses louder than the verses? etc...). The technical side of mixing will be to create the impression that you are listening to a coherent package. You started with individual sounds, your aim is to make the listener believe that everything was "recorded" as is (like the band played the complete tune in one time, and you just pressed record). If one sound sounds completely out of space, you've done a bad job.
The mastering stage : this is the most technical stage of them all. It's not here you will define the depth and movement of the song. At most, you'll try to achieve the things you weren't able to do in the mixing stage.
One thing to clear up, what most people refer to as mastering should really be called premastering. Mastering is the stage where the actual pressing/engraving is done (like making the glass masters at the cd pressing plant). The actual job of the premastering engineer originally was to prepare a mix to be fit on a certain medium (for example, vinyl has some constraints, like limited dynamics, care should be taken of bass levels and phase, and high frequency levels). Nowadays, the mastering engineer is usually the guy you go to to make your mix sound "sellable". You don't want your cd/vinyl to sound less loud or muddier than the competitor.
This stage is indeed done on the finished mix. In the pro circles, putting a compressor/eq on the master output while mixing is NOT considered part of mastering (still mixing). A mastering engineer will receive the finished mix (some standard formats exist for that, for your purpose let's just say the wav you exported). Remember that I told you compressors (and eq's too) react differently if you use them on individual stuff, or if you use them on complete mixes? That's why a good mixing engineer (always referring to the way accousting productions are made) isn't necessarily a good mastering engineer, and vice versa. But both know how to operate their gear properly.
That's why it's good to master your own stuff when it's for promotional/fun stuff. But if you are serious about it (you are signed or something like that), and you can afford it, get it done by people that are trained and have experience in the field.
You know, my dream is to become a mastering engineer once. But I must face the fact, either I would have to be an absolute genius, or I won't be doing it before long.
Most mastering engineers are already quite old. They've been recording/mixing engineers for years. They know how sound reacts. But more importantly, they know what to do to make something sound good. A mastering engineer must know a lot of music actually. If a client says to you, I'd want my stuff to sound like a '60s record, you first have to know what that sound is defined of, before you can even start making it sound like that.
A litte about normalisation vs compression : the main difference is that's it's completely different . Normalisation is nothing but a gain change (first the signal is analysed to find the loudest peak, then a gain is applied on the COMPLETE signal so that that loudest peak will get the value you wanted. It's nothing but gain, so no compression at all). If loudness increase is what you want, compressors/limiters are more suited yes. Again, it depends on your aim. Normalizing is a process that was added to simplify your job. Don't automatically normalize all your samples. If you would raise your fader a little more, it will be the same result...
