The suggestions about hearing tests, earlier in the thread, seems to me, a rather simplistic one & fails to recognize the real core of auditory perception - I would be much more interested in one simple question - "have you noticed any more difficulty following speech in a noisy background/environment?"
I know I have experienced this deterioration .

An exception to my decision to not post anymore here.
Great confusions about compression.
First a compressor can be used to increase the instant dynamic. If you tune the attack time long enough, the attack of the instrument notes will be unchanged, while the global level will be reduced: dynamic increased.
And we have to distinguish compression that can be applied to a single instrument, in order to "sculpt" his sound (exemple Mark Knofler's guitars), from global compression of the mix used in order to make-it sounding louder in the radio or allowing low levels listenings/keeping-it intelligible in a noisy environment, to the detriment of the physical pleasure of the "hifi" listeners.
Compression is not all "bad" or "good". it depend on the good tastes of the producers/musicians/sound-engineers/mastering.
Even if this kind of nuance can be a little complicated for naysayers or objectivists that lives in an ideal world of the absolute purity of the holly numbers who squat this thread with their religion ;-).
Music is created by musicians and technicians, that use their feelings and knowledge in a very subjective way, that you will appreciate (or not) with your very subjective point of view.

Good to hear from you T. I almost gave up myself to further contribute to this thread, (after 12 years) because I too don't appreciate being sniped at by people either. However, I DO appreciate your relevant experience in audio design, don't give up completely. '-)
Miklos, are you actually modulating 12 tones?
Maybe you mentioned it, in earlier post that I way
I ask now. Which 12 did you select and why?
and from the looks of it, well now I'm replying and
I can't see the FFTs.
Cheers,

Thanks, J.C.Good to hear from you T. I almost gave up myself to further contribute to this thread, (after 12 years) because I too don't appreciate being sniped at by people either. However, I DO appreciate your relevant experience in audio design, don't give up completely. '-)
I do have a lot of respect for all your work and contribution to the audio and musical history, as well as admiration for your never ending real passion for Audio. And I'm proud to have had the opportunity to exchange with you a little here.
I take this opportunity to also thank jneutron for his kind words and all that i learned from him and will continue learning by reading his messages. You represent everything I hoped to find here: an impressive expertise at the border of my meager knowledge, great clarity, simplicity, intelligence, great kindness, a real treasure.

"I'd assume are quite audible" - why?. From what I can gather RNMarsh is suggesting that the stock answer to such plots is that the fundamental signal will mask the audibility of the close-in frequency sidebands >-70dB below the main signal
I too would be interested in how music signal would have been differentiated (& with what characteristics) with the same jitter applied.Maybe Miklos has tried this although his test is from last year?
I'm not qualified to make a test like that, to many variables.

That would mean that you're down on one ear, loosing your stereo hearing.🙁

I guess you didn't try it then!

Could be.
Could also be my sensitivity to Temporal Fine Structure (TFS) in speech is diminished either binaurally or not. The intelligibility of speech in noise is diminished when TFS sensitivity is diminished.
TFS sensitivity also has a significance in music listening - predominantly in timbre, pitch perception although I don't notice any diminished music appreciation

You need to read up on the J-test as well, there's absolutely scads of energy in the sidebands across the spectrum. Here's a $30-40 USD board under similar testing (although if I understand Miklos's test correct, he made a test CD?) Edit to add: the plot of 3 that I quoted before is of 1 kHz sinusoid. Minus the huge amount of garbage that isn't harmonically related.

Would it make you happier if I said, "if jitter's going to be noticed, the plots given are the most probable?" In any case, the point was that Richard's barb was opposite of what he wanted. Why don't you take up your argument with him?

Yes, naturally I listened to music to, but if I couldn't hear to much on the 1kHz where would I go from there. The big surprise for me was that I practically had to destroy the signal before I could detect anything.
I’ve been this way all my life! I can hear stuff in recordings most can’t."have you noticed any more difficulty following speech in a noisy background/environment?"

So having a hunt around other piano music to see if their are examples of high reported DR and found another to add to my collection of highly dynamic music. Album details - Dynamic Range Database . Feldman isn't everyone's cup of tea but I like it.
Regarding following speech in a noisy environment. If I am in a crowded space I enjoy tuning into different conversations around. I seem to be pretty good at it. No idea if this is any measure of my hearing or brainDSP ability of just that I'm nosy 🙂

My water Lily are all vinyl. I'll go hunting for something downloadable that I might actually want to listen to more than once. Just to ensure I am being fair here, there should be no difference in DR between the redbook and HD versions of this as it is stated that no processing occurs downstream of the tape recorder? I'd rather buy two redbook titles to get a spread rather than one HD as we are only looking at DR/crest factor in this.
All you had to do is go to his web site and pick a CD version. sheesh.

Yes, that is what I suggested would be the stock answer. However, I, myself and me could accept that it IS audible.
That argument also comes from the often repeated -- its Ok to have some 2H because you don't notice it. Well, sorry, but I do notice it and so do many critical listeners. One way to describe its affect is it adds a thickening quality to the sound.

Just wondering your reasoning for your statement about audibility but I see you are reluctant to explain it/
Not to worry
I see from your answer that you assume listening to a 1KHz tone is as revealing (or more revealing) than listening to music.Yes, naturally I listened to music to, but if I couldn't hear to much on the 1kHz where would I go from there. The big surprise for me was that I practically had to destroy the signal before I could detect anything.
I just wondered if you had listened to music & what you perceived?
