Now that my play is over, it is with blinding speed that I comment on the ENOB exchange seen in this thread several pages back. Now, I may need to reread it, but the emphasis seemed to be on more bits equals more dynamic range. Fair enough, but there is much more involved.
Analog audio has increasing distortion with increasing level; digital audio has increasing quantization error (which translates as well to distortion)with decreasing level. The former, I argue is intuitive – the latter counter intuitive.
Just for the sake of a starting point, let us posit an analog signal to noise ratio of 72 db. It is a commonly accepted fact of analog radio voice communication that weak signals well down into the noise can be clearly understood. It is also clearly possible to hear subtleties and spatial cues into the noise on good analog recordings. In a 16 bit system, ther remain 4 bits worth of quantization. At this level, one has 4 bits of resolution which is a 1 part in 16 error, or 6.25%.
The way the Yggy works, we have 20 bit time and frequency domain samples inserted between the originals, which leaves 8 bits worth of quantization, with a 1 part in 256 error, or just under .4%. A lot better. This is exactly why Redbook 16/44.1 does not and will never scratch my itch.
I have been referring to the DSP in the Yggy as the megaburrito filter. In a recent conversation, Jason pointed out to me that it is really a megacomboburrito filter, since it uniquely optimizes time and frequency domains. This is what causes Yggy users, on a variety of systems to report hearing subtleties previously not experienced.
