In the Thread: What Passes for "Space" in Home Audio?
Post Subject: Do not argue, learn.Posted by Romy the Cat on: 4/18/2024
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.
