I sincerely feel that all those conversations about space
and the rest of the Audio G-spot words are irrelevant until people who engage
in conversation are exposed to a properly implemented Auro 3d or any other objects-oriented
Space reconstruction algorithm. All that Dolby crap, or what I do with
reverberation injection, is not genuinely proper space reconstruction. Almost
is hypothetically promising, but unfortunately, it has a lot of compromises as
they are trying to replicate what Auro 3d is doing poorly. They cannot break the
Auro 3d patent and use angles instead of elevations, a methodologically
compromised concept. A correctly implemented Auro 3d is a very different
reality.
Now the question is, what doesn't mean “properly implemented
Auro 3d”? In my mind, unquestionably, the main right and left channels should
not be included in Auro 3d and should be sourced directly from our high-end
2-channel systems. The better quality we have Auro 3D surround channels, the
higher the degree of ratio between direct and time-delayed surround channels
the system can afford. My *feeling* is that if we use regular consumer Auro 3d
processors and receivers for a typical $1K to $5K, Then we should be able to
replicate a small listening avenue with stunning results, assuring that the sound
from main channels is not compromised. If we go for full replication of a large
concert hall, I think the quality of surround DACs, amplification, and speakers
should be higher. I do not know if the contemporary few thousand-dollar Auro-enabled
receivers can deliver this quality. Also, the modern, the most expensive Auro
3d enabled receivers would permit time alignment, but to do it manually with
nine channels would be kind of a pain in the ass.
Bill went in another direction, and he has his Auro 3d
processor, which has a full-time alignment functionality integrated with
crossover functionality. This is amazingly comfortable; if you change your
crossover slope or crossover point, it automatically calculates time alignment.
Insanely comfortable! Now, an open question is how the quality of his DACs
compared to the quality of our selected high-end discrete DACs and how his
digital filters compare to the quality of our discrete analog filters at the
line level. I do not believe in digital filtration; it is my conceptual belief
as I insist that topologically digital cannot change volumes without impact on
sound intelligibility. However, my position may or might not be correct in practical
applications.
One way or another, any conversation about space
reconstruction makes sense only after familiarizing with object-oriented space
reconstructions. If you plan to explore this opportunity for your system then
buy tickets to New Hampshire, visit Bill and learn about his results. You might
or might not like everything he does, but I assure you it will give you much to
discover about space construction. I am hugely surprised that all those audio
morons who write for audio publications celebrate each month a new amplifier,
new fuze box, or a new cable elevator but did not invest any efforts to learn
how proper space reconstructions can benefit the listening experience. They
might do it now, as I did not follow audio press for quite several years, but
at the time when I was an active reader, I did not see any looking in that
direction.
