I think this whole Axe-FX and impulse thing is pretty dangerous TBH. People will compromise simply because they can, and when we look back in 10 or 20 years' time, the metal recordings these days will sound dated, if they don't already. You will invariably hear Superior 2, Slate, Axe-FX or impulses on the records simply because people were willing to compromise. The great thing about this industry is that if you strip it back to the basics and just capture a good performance, by a good performer, in a good environment, using good gear, your music doesn't ever have to be dated. As soon as you get into the 80s mentality of going overboard simply for the sake of it, you put a sonic stamp on your work that dates it to a particular period.
I feel that his will be the era of too loud, too dry, too sampled, too digital. Those traits are readily apparent in a lot of recordings today. As more and more studios adopt home/project studio format and large, vibrant, diffuse rooms with large-format multi-track analogue consoles become a thing of the past, we are going to see an increasing reliance on digital emulation, approximation and general imitations of 'the real thing'. Until digital technology gets to a point where the differences are so minute that nobody can tell, this is going to be a very dangerous period for audio. At least that's the way I see it.
This 'Slate generation', as I call it, is especially dangerous because it has the potential to breed a whole new wave of engineers who have absolutely no idea how to treat percussive instruments or capture them correctly. The Slate packs are so amazingly well constructed that most of us can't hope to even approximate the quality of those sounds on a session-by-session basis. How many of us have access to well-calibrated and maintained 2" machines, world-class outboard, and amazingly huge rooms to sample ambience in? As more lower-tier engineers duke it out by out-sampling, outcompressing and out-punching each other, there will be a foregone conclusion that you will HAVE to use 3rd party samples to be competitive. Everything will be about specializing and the margins for engineering will get smaller and smaller. This guy will edit your drums, this guy will tailor your drum samples, this guy will reamp your guitars, but at the end of the day what are you going to do yourself? I see this creating a generation of engineers with everything bottle-fed to them, and if you devalue the art and trade of engineering so much, how will the monetary rewards reflect that devaluation? It's a very dangerous time, IMO.
