这里是其中一段:MASSIVE Master 的发言
If the tracks are tracked where the gear wants to be (somewhere around 0dBVU / -18dBFS) it's almost difficult to get a mix to peak that high without trying.
I don't mix an awful lot anymore - But most of the time, they just "naturally" have peaks that rarely exceed -8 or -9dBFS.
Don't worry about "hot" - You've got more headroom than at any time since recording was just an idea. Use some of it.
Sidenote: 90% of the time, mixes that come in with "hot" levels, overly compressed for the sake of sheer volume at ANY stage (at the track level, at the group level, on the main buss, etc.) are the ones that don't have the potential to be "in-your-face" loud in the end. On the contrary - Mixes that come in peaking at -12dBFS, with barely any compression that didn't actually *serve the mix* -- Mixes that were well cared for, with generous amounts of headroom at every stage in the game - THOSE are the ones that have the most potential for sheer volume in the end. They're the ones that can handle it, they're the ones that have room for it. They're the ones that can "take the abuse" when the client says "make it freakin' loud."
But again, that's only about 90% of the time...
SO - Rule of thumb - If you're even the slightest bit concerned about your levels, they're probably much too hot.

the real issue that often gets over looked somewhat by many clients is actually how you get to the final value, not really what it is as such.
ive had mixes with peaks of -3dbfs and greater that have had very little compression, certainly none on the 2buss and as a result have been both dynamic, excellent sounding and using all of the 24bits.
others have come in where they have left me -6dbfs after reading some internet discussions but they have still limited or heavily compressed the audio to get there. as such its had "headroom" to them but actually had none at all. its been no different than it just being smashed to 0dbfs then turned down -6dbfs.
all you get from this is a quieter hypercompressed flat topped audio.
turning it down after this doesnt restore any of the space into the file.
as a general rule of thumb, anything that you apply purely for volume gain should be left off. 2 buss compression is great to use if it helps you get the sound you want on your tracks, its not great to use if all you are really using it for is to gain the audio up as far as it can go for example.
i know john (massive) goes on about this alot, for good reason, as do others but i'll say it again in relation to this anyways.
many people it seems need to think about and actually learn how to work properly in the digital realm. its actually alot different from the analog world.
you should use 24bits and record in with levels your interface is actually happy working with, anything from -18dbfs to -12dbfs peak values with faders set to unity. not only does this get a clean signal but it leaves tons of headroom on each track while still keeping massive quality benefits over 16bit recorded to 0dbfs.
once you start mixing you will find this massive amount of headroom really allows you space to both physically mix in without being cramped against the fixed 0dbfs celing and allows your mix space to breathe. you are able to leave tracks more dynamic than you would be able to do generally (if thats what you want).
you should find that not only is mixing easier but that your finished result has much more quality, seperation and depth than if you had pushed it all hard against the top from the start.
if you do this you will also find that its actually pretty hard to get anywhere near to 0dbfs without really turning up the master fader or using something to get quite a bit of gain. your mix will probably sit about -6dbfs peak but you will have not once had to worry about watching levels. you would then just send this, as is, to the ME who would eat up the remaining headroom and get it where you wanted it to be. mixes done this way are almost always able to go louder and sound better than those done hot from the start
its really desperately simple and yet so many people out there seem to not have come to terms with this but instead continue to record everything hot, push it continually hard against 0dbfs from the start, find mixing then much more difficult and suffer from all the common complaints
