-18db in Nebula? Is this a Magic number?

Postby superhero81 » Fri Sep 20, 2013 6:39 am

OK, so I have been reading more and more on Nebula everyday. Can someone please explain to me the deal with making sure Nebula is hitting around -18db?

How do I Monitor this? Within Nebula? Where at am I looking for -18db?

Also, I adjust the level using a trim/gain tool or my DAW's trim/gain on each track correct?

I also read you should normalize each track to -3db?

Anyway, please elaborate and explain this principal to me.
Thanks

It's different for different libraries, but that is the most widely accepted standard.

I am finishing my free preview video for 'Nebula Explained' right now called 'Secrets of Nebula Gain Staging'... all your questions will be answered there, in great detail!

We are happy here with -20.

Depends the rule. In CDA no rule, just check you monitoring CDAs. On broadcast ask before send. In Europe we are changing from EBU r-86 to r-128. You should check K-meter v2 for music.

Hi Superhero,

Gain staging is nothing new to the audio world of course. Most analog emulating plugins and/or convolution types also need to adopt the gain staging practice for proper handling of the signal. -18 dbFS is a widely accepted, varying to some degree as others have said, depending on the gear/developer. In the end though, while keeping the reference in mind as your guide, you should always still adjust according to your ears and using a good peak meter as your ultimate guide. Real world signals are complex and depending on harmonic information, dynamics, transients, and the like you can't heavily rely on RMS metering for example. Peaks dictate where your signals are; they lead. So if you are looking at a preset that needs -18 for example, in some specific case, it may turn out that -20 is better for it as your ears tell you and clip lights and the peak meter.

Sometimes a diagram helps relate the concept.

I have a better diagram [somewhere on a drive, but this one is OK].

Shows the relationship of Analogue/ Digital levels.

Hope this helps.
