Ok so we revived this old horse. Here are some things to keep in mind.
Time alignment and phase alignment are not (I repeat
NOT the same thing. You can adjust the initial attack but you'll wind up with weird phasing sounds in the tail end where the natural reverb of the room comes into play. This is NOT a viable method as you really create a delay between the two tracks but only in the tail end.
As for the drum technique comments, you apparently don't do too much "for money" recording or you'd find that you can't actually tell a drummer to go home and practice. You'll wind up with a band that doesn't ever book time again. At least that's true in my part of town. Sample replacement also smooths out the tonal differences between snare hits. Sample replacement is the same thing as Autotune these days. You need to be prepared to use it if you're looking to make music that comes anywhere close to top-40 radio.
It's honorable to want to make records on tape with minimal edits and capturing that "Magical Take" but bands just don't want to pay for the studio time that is required to do that. I LOVE The Doors and their first album was recorded over a weekend. It sounds great but there's too much imperfection (Humanization, Life, Soul, whatever you want to call it) for it to be truly commercially viable today in the form that was captured then. I caught some real flack on Moan Zone after saying something along these lines about the Beatles. I love the Beatles but we just aren't making records like that anymore, at least not for commercial release.
If you want to take the honorable road and try to capture that "Magical Sound" in the room with the band, you're probably lying to yourselves. Do you have compression? Do you use it? How about Reverb? Do you close mic the drums? Of course you do. My point is that those of you who are touting the high road of "Get it right on tape" are very right in many regards. Unfortunately, the tides have changed to a point where everyone wants Pink Floyd perfection on a budget that was equivalent to Pink Floyd's drug/alcohol/cigarette use for one day (I included Syd though).
The reason we use sample replacement, vocal track comping, compression, auto-tune and deep editing is because we're trying to fix problems because the band can't afford to sit there and record it 100 more times. If they were better, they wouldn't have to worry about it but last I checked, they're the ones paying and they decided they want to make a record. And after years of hearing radio hits like this, your ear as become accustomed to the sounds of these things.
I'm on the fence. If I have the luxury of getting it 100% perfect on a single take, I'll take it and be thrilled but my experience has taught me that this is really the minority of all recording sessions.
