so, 44.1/16 is not sufficient.
Well, if I understand the German right, they did illustrate that listeners could distuinguish a CD quality recording from an 'original' (how did they play back _that_ ?).The thing is that the results seem to depend too much on the used DAC rather than on the format itself, e.g. the 48khz DAC being chosen over the 96khz ones.
They had one very important test-setup for testing the main question, they asked: 96 vs. 48 kHz.as this would be dependent on DAcs, too, they took a 96 kHz recording, and used some downsampling to 48 kHz, and then playback through 96 kHz, again, to test this 48 kHz-signals gainst the 96 kHz-originals , both playable through same 96-DAC.
"in one test-setup, this was carried out similarily to 48 kHz, I had mentioned it above. They were aware of the fact, that every DAC may sound a different way..."
[...]what is flawed in this study ?[...]
...I doubt seriously that a 16-bit converter would produce perfectly bit-accurate output down to the LSB.
Numlock,now I am even asking myself, if you have read the study ?
they have never tested for 24 bit to 24->16 truncated, or 16 bit.hey, they tested 96 vs. 48 kHz @ 24 bit,those single 44.1/16 test showed the bottom line...
hmm, no, they have not tested every time another DAC.That was on purpose.If they would have done the opposite:only one DAC from one company, then we would cry (and we were right then): silly, test based only on one DAC, product.They compared each DAC vs. the original.and the testers should tell, which sounds better, DAC or original.and that leaded to intersting varying results.
It showed, that DACs behaved quite different !But it showed for the one 48 kHz DAC, that this was a perfect DAC, its output was indistinguishable from source/orignal. And the other 48 kHz DACs showed excellent performance, too.For the new 96 kHz DACs the results were different.
...it tells quite clearly, that 96 kHz is not necessary, 48 kHz are enough...
NumLOCK:Do you remember what I wrote you in the PM last week? 20bit/48kHz is sufficient enough for any high(est) end audio...
