Animaniac, don't take this the wrong way.
From reading your post's, I think this is a case of "you don't know what you don't know" right now", and until you start to know these things, you are going to have a hard time understanding what I am talking about.
Case in point.
The practice in Mastering is to provide a overall more consistent level of the audio. This can be accomplished in many ways. Mostly though, it entails running the audio through an EQ first, then to a wide band compressor.
Try this.
Take a vocal track and run it to a compressor only.
Now, run it to an EQ then to a compressor. Pay attention to EQing out certain overly hot frequencies.
You will find that on the second way of doing it, the overall level of the track is much hotter, and that the compressor provided much less gain reduction to keep the track sounding level.
Compression causes distortion. The more you compress, the more chance that you will hear the distortion. If you are compressing because the track suffers from some overly hot frequencies, you will have much better luck, and much less distortion potential by dealing with the overly hot frequencies USING EQ rather then compression. This is why I am not a big fan of multiband compressors. Used in extreme moderation, they work well. But it would be impossible to minimize the gain reduction on a mulitband compressor unless the mix was already very level in the first place.
Most of the energy in a mix is in the low end. With that in mind, if you are trying to acheive hotter levels, but the low end is constantly triggering compression, then you have a much greater potential of HEARING the results of compression (distortion, and generally a lack of detail in the low end because the distortion caused by compression usually causes a sort of "splashing" of the sound). Compression tends to "bloat" the sound a bit. If your bass frequencies are primarily what is triggering compression, then the low end will start to bloat out. In some cases, this is desireable, but usually on a very transient signal like a kick drum, or a slapping bass line. On a whole mix though, just about every instrument has low end information contributin to the overall sound. If those frequecies are causing the compressor to trigger, then you get an overall "splashing" of the the low end, and very bad sound in most cases.
The idea of eq'ing first is to ease back the low frequencies that are causeing the compressor to trigger. In this way, the compressor compresses far less, resulting in less "splashing" on the overall sound.
The bottom line is this. If you are getting good results with a multiband compressor applied across the whole mix, well, cool, have at it.
It is my belief though that much better results can be acheived using a bit of EQ before compression, and in this case, a normal wide band compressor will do the job just fine.
My practices in mastering are very consistent with what other mastering engineers predominately use. Like I said earlier, most do not use multiband compression because it is usually an unnecessary device during mastering. I am not saying that it doesn't have a place in mastering, or that in some situations it is not the best solution, just as a rule of thumb, it is not what is used.
As far as digital vs. analog goes, I am going to put together an mp3 with both formats on it. I will let you decide which is which. You will be suprised to hear that many people guess it wrong. I have heard far too many analog recordings that have a very harsh and brittle quality to them, and some of these were done using mostly class A gear and 2" machines. Let's face it, most of us cannot afford good analog. We can afford mid priced digital though, which is a far cry better in almost every case then mid priced analog.
As far as being a "pro', and acting like one. Being "pro" means I make money, which is something that has yet to result from me posting on this BBS! I DO NOT get paid to clarify the technical differences between TRacks and Wavelab with Waves plug in's.
If you found my "tube mic stand" joke offensive, well, sorry (not really but I am on record for saying it now...
). While you found that little joke offensive, it really illustrates the point about many software manufactures claims about their product, and the many unsuspecting people that buy it. TRacks is pushed as being a high quality solution to "analog emulation" mastering products, when in fact, it is just a low bit resolution DSP package that has a certain "sound" to it. It IS "emulation", and far from the real thing. If you have ever played around with any of the "real" units TRacks "emulates", you would KNOW that it is a far cry from these products. In addition, TRacks does NOTHING that you cannot achieve with higher quality mastering solutions, NOTHING!!! The difference is that the higher quality solutions can do so much more, and generally have the RIGHT kinds of tools for mastering for a majority of cases as opposed to a "sound" like TRacks which has limited applications in the real world. People buying TRacks as their ONLY mastering solution and using it on everything will soon grow tired of it's one dimensional way of making stuff sound. So, the joke really pertains to the idea of "tubes" are the only way to go in audio, and how silly that is. A tube mic stand is a clever joke that covers this concept rather well because ALL mic stand are generally made out of tube material (tube piping that is). Just like there is "warm sounding digital", and "brittle sounding analog", and harsh sounding tube gear, and warm sounding solid state gear. It is the quality of the gear that counts, not so much the technology behind it. But it is easy to make people think that a certain "niche" is the "magical" solution for everything. And that is exactly what the hype around TRacks is. So, sorry that you didn't get the joke.
