En bizony nagyon keves kulonbseget hallok. Akkor most vagy en hallucinalok, vagy te hallucinalsz, vagy mindketten jol hallunk, csak mashogy. Lehet, hogy nekem ezert jon be az analog hang, masnak meg nem?
A DNR/SNR keveresben igazad van, most ujraolvasva szerintem az altalam idezett cikk az SNR-rol irt, nem a DNR-rol. Folyt. kov.
Ennel erthetobb megfogalmazast nem talaltam:
"All other things being equal, when your turn down the bit depth of a file, all you’ll get is an increasing amount of low-level noise, kind of like tape hiss. (Except that with any reasonable digital audio file, that virtual “tape hiss” will be far lower than it ever was on tape.)
That’s it. The whole enchilada. Keep everything else the same but turn down the bit depth? You’ll get a slightly higher noise floor. Nothing more. And, in all but extreme cases, that noise floor is still going to be – objectively speaking – “better” than analog.
On Bits, Bytes and Gameboys
This sounds counter-intuitive to some people. A common question at this point is: “But what about all that terrible low-resolution 8-bit sound on video games back in the day? That sounded like a lot more than just tape hiss.”
That’s a fair question to ask. Just like with troubleshooting a signal path, the key to untangling the answer is to isolate our variables.
Do you know what else was going on with 8-bit audio back in the day? Here’s a partial list: Lack of dither, aliasing, ultra-low sampling rates, harmonic distortion from poor analog circuits, low-quality dither, low-quality DA converters and filters, early digital synthesis, poor quality computer speakers… "
...
"But despite all that comes to mind when we think of the term “8 Bits,” the reality is that if you took all of today’s advances in digital technology and simply turned down the bit depth to 8, all you’d get is a waaaaaaay better version of tape cassette.
There’d be no frequency problems, no extra distortion, none of the “wow” and “flutter” of tape, nor the aliasing and other weird artifacts of early digital. You’d just have a higher-than-ideal noise floor. But with at least 48 dB of dynamic range, even the noise floor of modern 8-bit audio would still be better than cassette. (And early 78 RPM records, too.)"

Szoval osszesssegeben arra tudok gondolni, hogy akik nem hallanak nagy kulonbseget a fenti 8 bit es 16 bit hangmintak kozott, azoknak jol mukodik a beepitett zajszurojuk, vagyis az agyuk hajlamosabb kiszurni a feher zajt. Hiszen a hallasnak csak egy resze, hogy a fuledben levo szerkezetek mit fognak fel, legalabb olyan fontos az, hogy az agyad mikent dolgozza fel a jeleket.
