Thanks Scott and George, that's what I wanted.I posted a set of multi-tones on the Linear Audio site, IIRC 48K is there corrected for unwindowed 64K FFT's for those using common tools. Windowing will only thicken the bins obscuring the low end, but multi-tones ONLY work at the target sample rate.
New revelation! Never thought hexadecimal was used in Revelation. 😀Almost biblical, the number of the beast is 666, or today 0110 0110 0110.
Richard, you have been living with your goopified DAC-3 for a week or more, now the honeymoon is over what are your longer term listening impressions ?.

It's always a great joy to see a real teacher at work. Your posts stretch and correct, very much like a good dance or combat instructor. You're (with a few select others) worth the (considerable) noise of the thread, and to the point that it's really valuable, for me anyways.Just to confuse some people you can tell them that in AM the carrier does not vary in amplitude (but sidebands appear) whereas in FM the carrier amplitude (but not its frequency) depends on the modulation
Much thanks, as always,
Chris
Huh? (My turn 🙂), Yes a mutual resolution limit between simultaneous aspects of time/frequency, position/momentum they are all analogous. What is contradicted, for a signal the time and frequency domain can not be simultaneously known to arbitrary resolution?
Ah, basically you wanted to point out that "concurrently" was the wrong descriptor as the known time resolution (somewhere between ~2 - 10 us) isn't "concurrently" enough, and that it further principially can´t be "concurrently" due to the uncertainty principle, right?
And of course it has to be combined with a "cheap shot", mhm? 😉
Sure that you don't use the demand for exactitude quite selectively?
it's painful to read the gross misunderstandings of basic signal processing and information theory that have been posted here this week.
Go ahead, it surely would help to address some of these along with some explanations and raise the understanding; I bet that it would be a reilef among the now common "lack of knowledge" shouting....
Shouting? I hope you're not trolling. Let me guess, when you refer to lack of knowledge you are meaning as regards psychoacoustics?I bet that it would be a reilef among the now common "lack of knowledge" shouting....
With "Lack of knowledge shouting" I tried to convey my (subjective) impression that posts not containing a "your lack of knowledge is......" line are really rare nowadays.
That may be so, but there is usually a reason for most things. It also depends what lack of knowledge you are referring to (because I believe you have something specific in mind)
The question was asked of RNM, not you.If he could compare it again to unadultrified the "just for fun" test may have some value 🙂

Even better if he could try recording the sound in the room, see if the difference is audible in a recording... Then we could all share the difference, that would be fascinating 🙂
Science's a bitch, really, isn't it?
No, it really isn't....
That may be so, but there is usually a reason for most things.<snip>
I think the reasons are, lack of good will, lack of manners and blindness to one's own lack of knowledge; you know:
He, who is without lack of knowledge, cast the first stone. 🙂
From the current online version of Encyclopaedia Britannica:
Sound - Noise | Britannica.com
"The ear actually functions as a type of Fourier analysis device, with the mechanism of the inner ear converting mechanical waves into electrical impulses that describe the intensity of the sound as a function of frequency."
And:
"The ear is responsive to the periodicity of a wave, so that it will hear the frequency of a complex wave as that of the fundamental whether or not the fundamental is actually present as a component in the wave, although the wave will have a different timbre than it would were the fundamental actually present."

That is without doubt true, there is evidence. It could also be lack of knowledge (it's not a crime) it depends what you are talking about😉I think the reasons are, lack of good will, lack of manners and blindness to one's own lack of knowledge; you know:

Hi,
I have been soooo busy moving that I have not been able to do much more listening. However, I will leave it on playing something in background mode until I can get back to serious (?) listening again.

This is a public forum, I am allowed to comment, did you miss the value of my comment (I'm guessing so for reasons you probably know)? Just in case, since a difference is often perceived as an improvement, it would be more useful to do the comparison again IMHO.The question was asked of RNM, not you.
Please refrain from sending me private messages in an attempt to censor me, I shall not respond to them, you have already said what you wanted to say here, which is fine, no need to repeat yourself 🙄

Ok, enjoy the background listening which ime is actually the best indicator, most of my listening is at low to mid/warm level, same as most households. I look forward to your report on this kind of listening, your spouse's opinion is appreciated too. I am sure you packing and moving is lotsa fun, good luck in the new place OS.Hi,

That's why I've written in a recent posts that the current model indiciates/includes such kind of transforms (some might remember the "spectral decomposition" mentioned in my post to the topic "connections of high frequency hearing loss and perception of bass attack").
This spectral decomposition takes place (must take place) due to the fact that processes on a cellular basis need time and the typical time frame is around ms, so one can not expect neurons firing every 60 us (for example), therefore some spectral decomposition must be present to encode the faster information in a channel of lower bandwidth.
At that point the so-called tonotopical mapping, that mmerrill99 mentioned, comes into play.
But, and I think that's the reason (or one of the reasons besides the egos 🙂 ) for the ongoing misunderstandings (or fights), in a general sense we are talking about models for our hearing sense.
And basically there exist two different kinds of models, so-called "bottom up" and "top down".
"Bottom-up" means in this case using the actual physiological mechanism for modelling purposes while "top-down" means using the functional response for modelling purposes without caring about the physiological details.
If people try to discuss about "hearing" but don't agree about the models (or level that is modelled) chances are high that it won't work well. Imo the discussions in this thread about "hearing" reflect this problem quite clearly.
If one is talking about "audiotory perception" it is about high level processes where conscious and automated processes of the brain/mind combination are involved, while talking about the cochlea (or more general the physological apparatus) is a low level area and there is a lot in between.......

What you have drawn from is this:-
'Let Him Who Is Without Sin Cast the First Stone'
As I understand, it is a quote from somewhere within the Bible ........ OK, but instead of saying what you really mean, you obfuscate it.
Please try harder.
