No, unless your converters are garbage, S/N isn’t an issue. Whatever you’re recording likely has less than 30dB of usable dynamic range. We’re not in 1984 anymore, where 30dB plus 18 dB of headroom would put you close to the noise floor. As far as your background noise, it makes no difference when you compress, the noise will raise. There is no benefit to compressing on the way in.

To do that, you will need to know what FS calibration standard they use. It sounds like they have no idea what they’re doing. Common calibrations would be -6, -9, -10, -18,-20 and -22.

Don’t record so hot. Should be about -18db average. Why would you be recording so hot in the first place?

When Melodyne 4 comes out this fall, its Direct Note Access will be able to do this. At the moment, there is no way to do it.

If you record in multitrack, you will be recording direct to disk.

No, because it can’t bd done. As a video guy, you can compare it to trying to remove the dark from something filmed at night with no lights and trying to make it look like a sunny day.

As I said, no magic involved and it isn’t recognizing the voice. It is recognizing correlated audio. There is enough of the background noise that is both correlated and uncorrelated that your ears are tricking you into thinking that it has been untouched. The fact is, you’re removing a large amount of the background noise with any of the vocal removal tools. And the “a capella” preset is doing the exact opposite. It’s leaving only the correlated audio. Everything you hear when you use that preset is exactly what’s being removed when you use a vocal removal tool.
What you’re trying to do does not work with your analogy. A much more correct analogy is that of trying to “unbake” a cake. Take a baked cake and get the eggs out of it. I dare you to try. A good scientist could remove and isolate large portions of egg product, but they certainly wouldn’t resemble eggs anymore.
The Center Channel Extractor works better than most tools because it combines traditional polarity tricks with FFT processing. You can read about the basics of phase relationship here: https://en.wikipedia.org/wiki/Phase_cancellation

Audition doesn’t recognize the voice. It finds and remove correlation between the two stereo channels. To properly isolate the vocals, there must be identical correlation in both channels on the vocals and zero correlation between the noise in each channel. As. you can imagine, that scenario isn’t very common.

Use the Center Channel Extractor. Using the standard channel mixer, it can’t be done.

Are you using a professional interface and mic? Compressing will highlight flaws in low-end or consumer gear.
