The VERY INTERESTING idea is that the introduction of noise as a dithering element for the analog signal (for our brain to decode) can be helpful in increasing the retrieval of information vital to conveying the Sound. Perhaps different types of noise would be helpful for different types of information: a regular repeating noise to improve rhythm, a repeating amplitude noise to improve dynamics, etc. Well, I am just thinking out loud now. But the idea that we can introduce specific types of noise or signal into a system to enhance capacity for information retrieval is very interesting. We only need to figure out what kind of noise to accomplish the tasks to do the experiment. Adrian

In fig.12, the low-frequency sidebands indicated with a gray "5" lie at the ±75Hz subcode frame frequency; the ones indicated with purple numeric markers lie at ±17.6Hz and its harmonics. These sidebands appear to be associated with the 4716 transport. When I used the 4716 to drive other processors, these sidebands appeared in their analog output spectra; if I drove the 4715 with my usual PS Audio Lambda transport, they disappeared from the 47 Lab's output spectrum (though the data-related sidebands were as strong as before).
