hmmmm...
Interesting discussion....
and well considering I'm outta the loop for recording until I can get set back up this weekend, thought I MIGHT be able to add a bit to this.
No one person's voice is going to be exactly like the others, so any one technique or software or set up is going to be right, its a use what You can and pick what You like or think sounds the best.
I personally use a variety of the things mentioned. The biggest one being vocal technique.
As Nick can probably attest I HAVE to work a mic, even the AT4040 that I'm using now, otherwise I'll peak out and distort.
Now, the advice about hanging, angling and singing about an inch below the mic itself is good advice, I actually do that myself, however I will also sing off to the side, or inch back a bit.
For example, if I'm looking for something with a really intimate light feel, such as with "Its Not Water" from the MC CD, I set up within about 1 inch of the mic, singing across the mic, giving that much warmer bassier tone, like Paul mentioned.
However for the rock stuff where I KNOW I'm going to be just going balls to the wall, to make sure that the track gets as much hootspah needed, and the dynamics necessary, I'll literally step back from the mic and sing OVER it, meaning on the hard belting choruses, I'll tilt my head back, so I'm literally singing across the mic but at an upwards slant, and step back 6 inches, it allows my voice to sound and feel the harder edge, but not distort the tracks, and at the same time keeps the verses from being too "low" in volume opposed to the choruses.
Tone is as much in how You sing, where You sing, how much You sing, as in any of the software, and gadgets You can put in line. It is also as much in learning how to manipulate Your own voice to achieve those tones, trying different ways of voicing or pronouncing words can dictate how hard Your hitting the track as well.
As far as sounding the same day to day...ummm...well to be honest. Unless You are going to sing faithfully every single day, with the same warm up time without ever getting sick, or having allergies or what have You. It just doesn't happen. However, having faith in Your ability to come close, that's all You can do. I will often work on just one part, get that perfect, and then not touch anything else until I know that I have time to complete the particular part in that same session. That's not to say I haven't spent hours one day, and then ended up re recording everything because I liked or disliked the tone more the next day.
Its like anything else subjective, but I'm still a firm believer in technique being the biggest discipline and the biggest consistant factor involved with good vocal recording.
And then again, I'm jonesin at the moment so, who knows maybe I'm just blowing smoke, I just know what works for me.
