Basic technical question about digital source signals
https://www.stereophile.com/images/712an.AN41fig03.jpg Not broken, a design decision to go NOS without a filter. https://www.stereophile.com/content/holoaudio-may-level-3-da-processor-measurements Or in this case, the option to run NOS or not without a filter. |
itsjustme When you over or up sample a signal the goal is not to magically create missing information from a vacuum. Its simply to move the noise ("steps") to a higher frequency so that they are more easily filtered out. Get i hgih enough and your ear will do it on its own. ------------------------------------------------------------------- Given the number of people who prefer nonoversampled DACs something seems wrong/incomplete with this theory |
You are equating accuracy with preference. That never ends well in the audiophile world. People will make up all kinds of justifications why their preference is "more accurate". But the key phrase here is "make up". Given the number of people who prefer nonoversampled DACs something seems wrong/incomplete with this theory |
Given the number of people who prefer nonoversampled DACs something seems wrong/incomplete with this theoryWell, first, i’m providing a technical answer. You need not like it, but it is true. Next, people have many opinions. Many are odd. Many will disagree. Look at politics. Third - done right i clearly DO like it, ad anyone who listens to bitstream or DSD is listening to hugely over sampled streams by definition. Fourth - we have no idea what was done in the anti-alias filter; that occurred in the studio. oversmapling was almost certainly employed, statistically, but we don't know. And aliasing is NEVER a good thing. It creates (maybe) tones that never existed in the first place. I cannot personally imagine how allowing hgih frequency junk through, or having brick-wall,phase incoherent filters can possibly be preferable, but hey. G |
