If some people do not want to better understand the sound frequency spectra that the science shows has a positive influence on human beings, and whether or not specific populations around the world are influenced any differently, and to utilise good science conducted by unbiased multidisciplinary teams of qualified experts to determine "How much?" of the frequency spectrum is truly important, is their own decision.
However, that will mean that they will likey remain in a state of ignorance as to this particular issue. Moreover, if they should go off and repeat the myth that all human hearing is limited 20Hz to 20kHz, and then jump to the inappropriate conclusion that "ONLY 20-to-20 is important" for digital sound capture and reproduction purposes, they shall do so without valid evidence. Further, the attidude that "We already know it all" is the kind of attitude that holds back scientific inquiry which normally leads to needed technological advances.
People have been complaining about the sound of digital for years. This continuing digital state of "not quite right sound" (to put it mildly) raised some serious questions, many of which remain unanswered. When you have people making comments such as "Listening to digital is like sticking an ice pick in my ears," despite 25 years of "efforting" by the chip makers, then it's clearly time for digital proponents to do some rigorous re-thinking, if not, some rigorous soul-searching.
Having a complete, comprehensive, freely-accessible, scientific database that has been compiled by unbiased multidisciplinary teams of qualified experts and has been properly "peer reviewed," as has been suggested above, will clearly aid those who want to improve digital sound quality.
Some people here seem to have an irrational fear against even making more accurate scientific inquiries, let alone, an irrational fear against the coming digital technological advances. Perhaps part of their irrational fear and lashing out at the messenger is based upon the knowledge that "All digital gear is obsolete on the day it was designed" and that they will sooner, rather than later, be forced to junk what digital gear they have and buy new gear, I dunno
"Why" do I prefer the sound of analogue over digital? That's a good question. I suspect, I cannot now prove, that analogue technology captures the emotions and translates them to the listener better. As a direct result, people like me, and many musicians prefer the sound and the expereince of analogue.
As for analogue technology's so-called "limitations" being thrown up again, I see that as a smokescreen, an attempt to deflect attention away from honestly acknowledging the many deficiencies in digital, including, but not limited to, math errors, inadequate communication speed, total system thoughput problems, and the poor CD and MP3 formats. The attempt to throw up such a smokescreen rests upon a logical fallacy and is being used by some to try to hold back both scientific progress and digital's coming technological advancement.
I suspect, but cannot prove yet, that removing the artifical and arbitrary 20-to-20 frequency barriers from digital, thoroughly examining the data of the "important" frequencies for human populations to experience pleasure compiled by unbiased multidisciplinary teams of qualified experts, will result in the clear need to increase digital sound's sample rates. The decision to do so will thus rest upon a solid foundation of peer-reviewed science.
I also suspect that the bit-depth in digital sound will need to be increased far beyond the mere representation of the sound wave, there will be some waste in the form of additional unused bits, but this "bit waste" will be more than offset by corresponding boosts in overall system performance. As it is, inadequate bit-depth is something of a barrier to system throughput, it reminds me of the old 640K memory barrier, where the intermediate process of memory bank-switching could not be eliminated and slowed the system down having a negative impact on system performance. In any event, whether I'm right or wrong about getting more overall system throughput by bit-depth expansion, bit-depth expansion in digital sound will still need to be addressed. Any bottlenecks that can be removed, should be.
In the meantime, people can hire wonderful analogue facilities all over the world. This is a great idea because even the digital advocates admit they like the sound of analogue and one also can satisfy the needs of those who still prefer the sound of analogue, such as, many musicians.
Happy musicians means better performances, therefore, hiring an analogue facility makes a lot of good sense.
Cheers.
