Tudomanyos indok van ra csak igazan, csak folyamat irjatok itt a baromsagaitokat. Ha a fuledben nem is hallod a kulonbseget, matematikailag mindenkepp letezik.
De biztos neki is a gyikemberek vittek el a hallasat:

I think selling 24/44.1 files as high resolution is a bit of scam for many kinds of music.
I just compared the 16/44.1 version of Lana Del Rey's Born to Die album to the 24/44.1 version sold on HDTracks. They sound identical to my ears and Jriver says the dynamic range of the first six songs is the same (6, 5, 5, 6, 4, 4). This suggests zero benefit from the extra 8 bits of headroom, for this album at least.
BTW, I have a vinyl rip of this album (24/96) that kicks both 44.1 versions to the curb.

Sampling Rate Discrimination: 44.1 kHz vs. 88.2 kHz
It is currently common practice for sound engineers to record digital music using high-resolution formats, and then down sample the files to 44.1kHz for commercial release. This study aims at investigating whether listeners can perceive differences between musical files recorded at 44.1kHz and 88.2kHz with the same analog chain and type of AD-converter. Sixteen expert listeners were asked to compare 3 versions (44.1kHz, 88.2kHz and the 88.2kHz version down-sampled to 44.1kHz) of 5 musical excerpts in a blind ABX task. Overall, participants were able to discriminate between files recorded at 88.2kHz and their 44.1kHz down-sampled version. Furthermore, for the orchestral excerpt, they were able to discriminate between files recorded at 88.2kHz and files recorded at 44.1kHz.

Megjegyzem az illeto pont az ellenkezojet tapasztalta mint en: en a 16 vs 24 bit kozti kulonbseget hallottam, igaz dinamikusan tobbet valtozik a magas hang az altalam hallgatott zeneben, o meg a 96 es 44.1 kozott hallotta, a 16 es 24 bit kozt nem
Egyszer amugy egy csapat ujsagiro is korbejarta a temat, es mind hallottak kulonbseget egy rendes studioban (valaki magasnal, valaki melynel, valaki meg megallpitotta hogy maga a tul jo minosegu master tul tiszta es ezert neki rosszabb), de nem talalom a cikket :(
