Mixing Headroom Premaster

Just wondering where all you Hi End guys stand these days on how much room to leave for mastering on your final mixes...i feel like 32 bit recording has changed the way we might do it a little.

Thoughts...

I honestly don't think about it at all.

Like most people, when I'm mixing on my desk, I'm usually hovering around 0VU, which ends up with peaks between -6 and -3dbfs on print back.

When I'm ITB, levels range from -10 to -0.1. As long as I'm not lighting up any red lights in the DAW or somewhere on my DAC, I'm happy.

The only reason I even know those peak values is because I usually Audiosuite 2 or 3db of limiting on refs I send to clients, so I check my peak values before typing in settings on the limiter. Otherwise, I don't think I'd know (or, frankly, care to know) where those peaks are hitting.

also...isn't leaving room for mastering playback important...gaining 24 bit files down at mastering is not ideal...is it?

So I can apply it after the mix is printed quickly before sending out client refs. The limiting isn't present on the actual mix; it's simply added for the clients' listening pleasure.

If you're not clipping, you're fine. Turning down a 24 bit file is not a problem in any way.

Right...never done that...good idea as opposed to a plug on the master

I completely disagree. If a mastering engineer has to turn down a 24 bit file at all, there will be an instant affect to the depth of field that the ME will have to work to get back.

A 32 bit file is completely different ... I'm still learning what recording 32 bit files is al about...it is definitely something I like.

It's not a matter of agreeing or disagreeing. What I said wasn't my opinion.

Lives for gear
The noise floor of 24 bit is -144 dBFS. The noise floor of a chip is around -115 dBFS. The noise floor of the best analog chain knocks that down another 5-10 dB. The buzz of your guitar amp, when nothing is playing through it, knocks that down another 10-20 dB probably.

So that's the reason you can turn a 24 bit file down a little without any worry about it being an issue. All the other noises in your chain significantly outpace the noise floor of 24 bit.

Back on topic though...nobody's noticing a difference with 32 bit files...sonically I mean? How about delivering 32 files to mastering?
