Can System Noise be saved to HDDs, SDs, etc. in digital audio files?

[Ralf11]

If so, how many dB below the signal is likely?

 

Or... will it be extracted at all?

[Ralf11]

Barry D disagrees with [SandyK's assertions]. He says that a properly ripped CD sounds identical to what he provided for production.

Here are his exact words:

On the other hand, when properly ripped to hard drive in a raw PCM format (such as .aif or .wav), the results *are* to my ears, indistinguishable from the master used to make the disc from which the files were ripped--even with that pit structure revealed by the AFMs.  I haven't found any exceptions to this yet in over 30 years of comparisons.

Sandman, your surname is indeed all over this site - and elsewhere

 

if you really want it to be a secret it is too late; but maybe you can be redacted

I suppose for clarification, rather than will it be extracted, did you mean can it be extracted?  I vaguely remember info about how noise can effect the cleanliness of the actual stored data on a hard drive.  Of course none of that effects the actual data values, and when that data is used elsewhere it bears no relation or hidden evidence of the environment in which the hard drive operated.  

 

So a very iffy qualified yes, with an addendum that when the data is moved the noise is not there in data nor can it be retrieved elsewhere nor can it accumulate further downstream.   It isn't in the data, it might be in the method the data is stored, and could only be retrieved by some method unrelated to the data itself.  So there would effectively be infinite db between data and this system noise.  

 

I meant is it likely to be extracted during normal use.

 

Of course if it is impossible then it won't happen during normal use.  (except in the upside-down world of audiophoolia, where if it is impossible, then it will happen a lot)

[Ralf11]

I think a thread on "likely mechanism(s) responsible for audible differences at the point of D-to-A conversion" would be very worthwhile, and encourage someone to start it.

 

I appreciate that some people want to believe certain things, half.  I do not belong to that religion and am interested in finding out what effects noise can have on SQ in a digital system.  There are procedures for finding out how reality works, and even if they require a lot of effort in this area, some mechanisms by which noise can affect SQ can be characterized, narrowing the list of possibilities for the consumer.

[Ralf11]

I am still waiting for a description of the methodology, Sandy

[Ralf11]

also specify what system is needed to hear these tiny changes in SQ

This is an Audiophile forum , NOT a sub branch of Hydrogen Audio, .although several of you appear to be trying to make it one.

It would be a shame if just for once that you said something directly on the subject instead of referring non technical members  to a textbook that they would need to purchase, perhaps to refer to just once, then put it back on a shelf or in a cupboard never to be used again.

 

Yes, that's right - we should never have any technical discussions here.

 

Audiophools might learn something and begin to think for themselves.

 

and HERE is a textbook for you:

 You really are full of it. I don't do DBTs because they would carry no weight with anyone.  

 

 

You don't do DBTs because you do not know what they are, much less how to do one.

 

Your own statements a couple posts above that on contradict it.

 

The real question is why this notion you have is so important to you.

 

 

I like to use the term 'notion', jabbr likes 'thought' - either way it is not a result, theory, or finding.
