I may have cooked the few brain cells, containing my scarce knowledge about the respective matter, during my first whole day out in the sun today, so bear with me…
Isn’t real world, band limited digital 0dB, white noise a random signal having equal intensity at different frequencies, giving it a constant power spectral density, and when measured, the maximum level at each frequency will be 0dB?
Beauty would be seeing clipping occurrences quite constantly, compared to using a sweep.
Just seemingly endlessly played respective test signals from Qobuz, as well as ones generated by REW, while using my roon-dynamic-range-metering-bridge and Roon’s clipping indicator.
Got really confused for a while, as I still had crossfade and volume leveling on, interfering strangely sporadically with testing.
But there must be some truth to your comment, because I could set digital gain higher before clipping occurred with white noise, as compared to with a sweep.
Can’t really wrap my sizzling brain around it, currently…
Got any more pointers for me to better understand, AJ?
I finally returned to my tried and working (for my setup) method of setting maximum gain with pink noise, since its spectral intensity distribution emulates real music much better.
