A lot of us take the art and science of mixing and mastering music very seriously. Most of us focus on one thing: the quality of the outcome. Who cares how you do it as long as the end result rocks, right?
People like drama. People like to be different and unique. People also experience confirmation biases, placebo effects, and flat out just have passionate preferences. It's these folks that are carrying on an eternal debate within the studio engineering community. Let me explain the debate and then I'll be the voice of reason and wisdom (which will go unheard, because some people don't argue to find an answer, they argue for the sake of arguing).
That's the question that sparks the controversy every time. If you're reading this you might already be aware of both sides of the argument, but if not let me summarize it real quick:
ITB: Cheaper, Faster, Same Results
Outboard: Infinitely Better Results
The basic question is whether or not we should accept mixing with digital plugins inside of a computer or if we need to be routing analog signals all around the studio through tons of machinery to get better results.
Here's what people claim. No amount of double blind scientific experiments will get people to change their mind. No amount of exposing their own psychological flaws will change them. They know these things to be true. These folks exist in every industry and are basically suckers for marketing. Who are they?
None of this is an exaggeration.
However, it's an overkill in terms of this conversation, but I mentioned it because this same type of thinking exists in a lot of the out-of-the-box mixers.
But is it the truth?
No, here's the real deal that nobody is saying out loud. They are hiding their true intentions and motivations for saying a lot of these things...
There's one reason people who prefer mixing with external studio hardware claim for their ferocious opinion on the matter: "It sounds better."
There's for real reasons for them saying this, and they are:
That's the real deal.
Now check this out. I think the entire argument is stupid and will explain why in a second. I'm in agreement with the guys who prefer In-The-Box mixing. With that being said, I prefer outboard mixing! I have a lust for more gear. I love tinkering, collecting, testing, and just playing around with it all. It's not a big deal. I think it looks awesome and I love it when folks walk into my studio and get their mind blown from all the hardware with crazy knobs and blinking lights. It makes me feel special, talented, etc.
Anything and everything being done in the analogue realm in terms of compression, equalization, reverb, delays, etc... all of those effects have been perfectly emulated in the digital realm. But there's several huge advantages to mixing with plugins inside of a digital audio workstation.
When you keep passing an analog signal through a ton of cables and instruments, its picking up electrical interference. It's an electrical signal that can be altered by other electrical signals. Sure, our cables shield from a lot of it, but the longer that signal exists out of the box the more susceptible it is to these problems. When you get your signal into the computer and keep it there, you're now messing with binary code that can't be destructively altered in any similar way. (Of course, unless you save over your file or don't take backups and the file becomes corrupted, but that's besides the point.)
"Yeah but you don't get that analog warmth!" Except you can. When plugin developers saw this part of the argument rising, they realized that a lot of it was legit. You can listen to old records and hear the pleasant saturation of tapes and transistors and vacuum tubes. This is just harmonic distortion. The developers wrote algorithms to not only supply you with the same saturation, but with variable controls so you can choose exactly how much and where. That's far better than having one setting that you can't control, minus an impedance switch here and there.
Back in the day, studio engineers had to have assistants who would run around with sheets of paper with knobs drawn on them and mark down the position of each knob, fader, etc. It was absurd if you didn't finish the mix in one sitting. And if you committed it to tape and the client wanted a change, well guess what? If you wanted to make dynamic changes to volume throughout a song, you had to ride the fader with your hand and nail that performance live too.
Nowadays, everything is digital. You can save your settings. You can draw in automation lines for your "fader rides" digitally with perfect recall every single time. You can copy, paste, undo, redo, save projects, reload them the next day in 3 seconds... Considering the perfect software emulation of hardware, why would you not take advantage of this feature? Especially when clients are going to ask for very minute and detailed changes several times over.
There's some hardware you can't go without. You can't record sounds without a microphone, and you can't boost that mic-level signal to line-level cleanly without an awesome preamp. Beyond that... why pay $4,000 for a single channel 8-band equalizer when you can pay $100 for a 16-band or parametric equalizer that can be slapped on as many channels as you'd like at one time? Consider that it's the same company selling you the software version of their hardware EQ... It's pretty much the exact same thing.
Here's what I think is the main benefit to mixing outside of software. Besides the marketing and visual aspect, and the fun of routing signals and summing together externally, and everything else we mentioned above...
The main benefit is psychological. You have to dial in your settings, tweak it, get it right, and commit to it. You don't get to play the game of doubt and return to the mix 30 times over the next week until it's not recognizable any more. You learn to trust your ears, use them while they are fresh, make the final call, and accept it. That's if you're ballsy and ready to walk the razor's edge.
Otherwise, you can mix stems of just drums, just guitars, just vocals. Even then though, you're going to waste a lot of time double guessing yourself. The psychological benefit builds confidence and helps you increase the amount of work you're pumping out, which means more money for you in the end.
Here's what I think the solution should be. There are three options:
It's not a binary situation. You can have the best of both worlds, which is what I prefer. I honestly can't afford 16 channels of everything from compressors, EQ's, effects processors, converters, patchbays, cables, preamps, and a summing box. I use what I have though in a way that keeps my workflow fast and efficient but gets my rocks off because I get to play around with these awesome pieces of gear.
The best advice for any newbie is to record absolutely dry signals. But if you're not a complete newb then you can commit some effects to the take before it ever hits the DAW. I always include a little compression and EQ on the way in. A lot of times I'll go all the way with those two effects. If I don't go all of the way then I can route back out later and finish the job and commit the mix to a stem, such as all of the drums. In the end once I know my stereo field is perfectly panned and balanced in the frequency spectrum, I'll bounce these stems through the various pieces of outboard gear to emulate what I set up in the plugins (or go for it live).
In this way I've had my fun, I didn't waste a lot of time, and I have my stems I can send back in and sum digitally into one final file. This way, if someone says "can you turn the vocals up in the mix a little bit" I can do that in a matter of minutes. If I'm smart I've already done it and delivered variations for them to decide from.
So my point is... this black-and-white style of thinking usually has an agenda behind it that benefits those arguing the sillier position. There is typically some merit to what they say, but it allows them to slide in ulterior motives (such as raising the financial barrier to entry for other mixing engineers).
Never fall for black-and-white thinking. Polar extremes are never good, when you can have the best of both worlds! And if you can only afford default stock plugins, then start mixing while having spent zero extra dollars! It's all good enough.
It's guaranteed that you can put a completely in-the-box mix next to the exact same mix routed through hardware and not even the most professional mixer could tell you the difference if it's done right. That sentence right there will cause an entirely separate argument...
Why can't we all just get along!?!?
