Look, it is just like the hardware world - it depends always on this or that particular hardware/Nebula preset and how it was sampled. There is only one simple rule - do not go over 0dBFS.babiuk wrote:I am even more confused...
I think an audio with -18 rms and -10 peaks will get more benefits through a neb preset than an audio with -10 rms and -18 peak levels
So you support guys are saying we don't have to worry about rms level coming into nebula just be careful about peak levels?
The -18dBFS peak is just a guide. You would expect to get more of the subtle Nebula distortion above it. If you want to push it hard - do it - just watch out for the clip indicator.
But also bear in mind that if the preset is from, say, a super-clean, high-headroom modern S*L preamp, you may not hear a change at all at different input levels (as it would be mostly phase distortion that Nebula has captured, not harmonic distortion - the device wouldn't have almost any harmonic distortion at levels from -18 to 0dBFS peak). So it is always preset specific, just like in the hardware world - you must learn every single preset and the best way is - use your ears and don't clip
