1) Personally I hate it. But sometimes it's a necessary evil.
2) Same as anything else - "It depends" - But usually stem tweaking (if I can help it) is done digitally and then routed out as one stereo output through the garden.
3) Eh, I almost always mixed to stems (this is back in the 80's -- It's been available a lot longer than digital...). That said, no doubt plenty of times these days it's used as a crutch on good days and an excuse for bad monitoring chains and engineers that can't just commit to something on bad days.
4) I still treat nearly every project as if its next stop was the lathe. I'm not a "vinyl nut" (although I certainly enjoy it occasionally and I probably have more 180-200g half-speed cuts than regular stuff) but the physical limitations of vinyl (and there is a certain amount of subjectivity in this), IMO, made for a better sounding recording. Not that
vinyl was the reason - (and there's the rub - was vinyl the catalyst?), but the simple physical properties prevented things like having the "anchor" of the low end off to the sides or having phase issues in the low frequencies or excessive sibilance and the like -- Things that are somewhat commonplace on a lot of recordings made by "less seasoned" engineers.
A recording had to "deserve" being put to vinyl. It didn't have to be amazing or anything, but some of the stuff that's out there these days, you'd just have a stylus skipping across the surface. And go figure, those are the ones that were "Ozoned" or otherwise seriously messed up somehow.
5) Yes/no. The loudness war is a pissing match between artists and labels. The listening public (A) never asked for it and (B) would probably be absolutely shocked if they knew what they were missing.
If I don't do what the client wants, I'm not going to have clients for long. Sure, I'd love to find some niche market where I'm doing nothing but Chesky-type recordings (where it's all about
sound quality & purity and NEVER about volume) but that isn't likely to happen. Till then, I (we) do what I can to "limit the damage" (for lack of a better term). Gear that handles absolutely obscene signal voltages without (sonically) falling apart, converters calibrated to bring those voltages back to something more reasonable for the purpose, etc., etc.
6) I won't only pick one. 95% of the time, I use Samplitude. The other 5%,
WaveLab is like a "Swiss Army" knife application. I
need both. If it makes a difference, every single project is processed and routed through Samplitude. But WaveLab needs to be there for -- things that might come up. I'm convinced that you could open a photograph as an audio file with WaveLab if you find the right settings (and they're setting that you can actually tweak in WL as you can't in any other program I know of).
The majority of the time when I'm working on my bike, I can use sockets, box-end or open-end wrenches. But when I'm working on the clutch plates, it's an 11/16", box-end, deep-well wrench without exception. There is no other "right" tool for that task.
I far prefer the workflow and DSP of the Samplitude/Sequoia family. But that's me -- I know plenty of people who prefer WaveLab also. In either case, there will always be a reason for me to have both.
