NEW: Volume Leveling uses the additional Headroom provided by Internal Volume
lisbethfox:
Well heres the thing, I generally turn EVERYTHING to 0 (aka no volume reduction) for films because my system is calibrated to 85db with 20db of always available headroom. Hence even when I go to internal volume, as long as the films mix is properly spec'd and done it should be always set to 0 in my room. I use this for mixing 5.1 content occasionally so no sort of attenuation is important to deliver a cinema mix.
lisbethfox:
I also have a pretty serious collection of actual cinema mixes (much better than the horrible ones released on DVD and Blu Ray in some cases) so like, they're all just designed to play at 0dbs of attenuation as long as your system is set up to mixing spec.

You'll lose a lot of the advantages of internal volume if you have your reference level set to 100%. Personally, I have my system calibrated to output reference level at about 75%.
Additionally, if you have a look at the R128 analysis on most films, you'll see that they're often a dB or two off of the calibration standard. Many of them need boost to actually be at the cinema calibration target, etc. If your reference level is 100% you can't use software volume to adjust for those films that were mastered on the quiet side.
Regardless, if your plan is to have software volume maxed at all times internal volume doesn't necessarily offer much advantage (one of the main advantages is the ability to utilize the headroom for creating a level volume between differently mastered media, and doing DSP). If you transition to pure software volume, I'd recommend recalibrating so your reference level is lower than 100% so you have room to grow if you need to.

Ok interesting.
You seem to know what you're talking about. I'm a rookie at this gain structure stuff, I don't have much industry experience, just access to some fun content and the occasional indie job.
I have often run into recordings without that extra headroom and craving to turn it up louder (some classical SACD's are quiet). I guess my next question for you is, JRiver does all this stuff at 64bits? It says processing internally, 64bits. If so that pretty much removes any chance of the gain changes affecting quality? (at least from what I understand)

I think I saw this, do you have a link?
