All those Creative products marked with "100 dB SNR" and "24 bit 96 kHz" suit for computer acoustic systems, including even the most expensive Creative MegaWorks 510D computer speakers at $400.Klik.
Before going any further, however, we'd like to make a couple of small things clear. In fact, ever since Creative Labs first rolled out the Audigy, they have been making claims about their communications card, which is questionable, to say the least. First of all, they claim that it is capable of 24-bit sound sampling at 96 kHz. The 24-bit logo appears all over the place - on the box, on the installation CD, even on the product itself. Yet it has been confirmed, even by Creative Labs' own technicians, that neither the Audigy nor the Extigy are capable of recording or playing 24-bit sound at 96 kHz. There is actually entry-level support that the card automatically downmixes to 16 bits / 48 kHz to process the sound. So why is the 24-bit logo featured on packaging for products such as the Extigy or the Audigy cards? Then there is the fact that this same logo indicates a signal-to-noise ratio of 100 dB, where our tests have shown that neither the Audigy nor the Extigy are capable of levels above 90 dB -- and even this is less than optimal, for both analog and digital.
Also note that 106 dB A and 103 dB A is A-weighted noise power with no signal. Creative in its Extigy FAQ gives a wrong definition of SNR: "less noise at any given signal level". With signal this parameter falls to -95 dB for the front channel and -90 dB for others (THD+N).Nekako so izgleda vzeli povprečje... signal in brez signala, čeprav se strinjam, da je to zavajanje kupcev, saj je to signal/šum in ne brez signala.
It seems that the recording is implemented in the 8bit/22kHz mode and then calculated into 24bit/96kHz.in tole:
At last, we have the 24bit/96kHz mode which is currently working incorrectly., toda funkcija 24bit/96kHz ostaja, čeprav trenutno še ne dela najbolje.
Yet it has been confirmed, even by Creative Labs' own technicians, that neither the Audigy nor the Extigy are capable of recording or playing 24-bit sound at 96 kHz.
