Oh, seems like I forgot some more examples outside the reamping situation.
2. How do you know how "hot" the signal coming out of the Profiler is? If you think of a very soft signal, e.g. some very mellow playing without any strong transients, does that actually need a forced -6dB pad to please the -12dB RMS police? Hardly.
That is the point where the 0 dbfs is a moving target.
A dynamic signal that has not gone through a limiter (e.g. at mastering) yet, is always prone to be pretty soft, or hit the full scale boundaries the next second.
When we investigated the complaint issues of "too much digital level", I found out that the SPDIF level gets internally boosted by 6 dB, which does not do any good. I got rid of this internal 6 dB boost as a consequence.
Seen from the Profilers perspective, we have brought back the signal to our 0 dbsf definition.
