That is all, thank you and good night.
If you doubt me, go get some high bit-rate CDs and listen to them.
Your Universal Singular Perception Theory needs a little more work.
For it to be true, you would first need to explain the difference between perception of Flourescent Lighting and Filament based lighting devices.
All those headace and Eye strain sufferers must be wrong, then.
After all, Light is Light, right?
😉
According to the math, we still have another doubling of Bit Rate and Sampling Frequency to go before we really achieve parity with the best analog recording.
No. That is a terrible analogy.
Light is not equal to all light. This should be easy to know.
Different chemicals produce different patterns - different frequencies, different colors, and some are more susceptible to electrical circuit flaws.
Sound, however, is sound, to human ears.
It is a vibration frequency through a gaseous medium.
The only sound that a human will ever know exists, that is outside of the human ear's range, is the "sound" produced by low frequencies.
Basically, put it this way: the human ear, on average, hears between 20Hz and 20KHz (aka 20000Hz). Now, some humans will have better hearing above 20KHz, some a little better at the low end. And then there is differences through aging - hearing ability worsens, so you will lose some at the high end. The high end is more susceptible simply because it is so much more noticeable. They are harder to detect, so a less perfect ear will not notice.
The low end, however, requires less effort in the ear, thus the average, and even after accounting for age, tends to stick pretty roughly to 20Hz. Genetic differences might make this different for individuals but age won't do so much, unless actual damage was done through the years.
But as far as actual hearing/perception of sound... anything above what the human ear can perceive (through physics, meaning what no human can hear, so basically 23000Hz and above I believe.... some humans can only go to 19000Hz and I think some can go as high as 22000Hz or a little higher, might be wrong but let's go with that for the example)... the human body will NOT know there is any sound being emitted if it is at [let's say] 25000Hz. HOWEVER, a human will perceive 10Hz, even though it is below what the ear can hear. Low frequencies will be perceived due to the vibrations. They are so low that our bones and flesh will actually feel them due to the way the pressure of air vibrations move through our body. That is why low frequencies can be difficult to locate the source, and is why the placement of a subwoofer in a room has little consequence (there is consequence, but that's a whole different matter, mostly related to room design and not our ears).
In short, actual harmonic frequencies above our range of hearing have no impact on the way we hear any certain sound. We cannot feel them, hear them, or detect them in any way using our body. Any claim that their presence in music has an effect on the perception of the quality of the harmonics is complete bullshit. Any source claiming this needs to be completely disregarded.
