and the one most interesting right now:
ASUS Xonar 7.1
The first two have a 'sample rate' of 96khz,
while the Xonar has a 'sample rate' of 192 khz (which is the rate that the more expensive cards next step up (about double) have.
Does the 'sample rate' matter any? I cant find any info on this.
Anything anyone knows about any of these cards that fall into the category of 'Its great, except I cant believe they didnt include.....with it, so I cant use it'
Well, in theory the higher rate means better quality sound if the source is also that rate. For instance, blue ray audio is usually (always?) 192khz.
You'd have to ask an audiofile if it actually makes a difference to your ears, as I cannot hear the difference at all. Though I can't tell the difference between my friends 3 grand sound system and my "came with my tv" stereo.. Probably not teh one to ask. lol
The quality of reproduction is dectated so many factors (not only sampling rate)
1)linear/non linear ADC
3) Quantization Error
4) Aperture Error
5) Sampling Rate
On So on...
Since the discussion is limited to Sampling rate. Below is the Nysqust Sampling Theorem which to summarize means
"to create an accurate reproduction of a signal (S) with highest freq component (f) the minimum sampling freq should be 2(f) but limited to sign(S)<(f).
"The higher sampling frequency will result to better signal reproduction"
