Only if you promise to be one of the everyone.
Why? Set up the test. Show the people here that they can't tell the difference between high res and CD as you like to claim.
Did Amir Change Your Mind About Anything?
It’s easy to make snide remarks like “yes- I do the opposite of what he says.” And in some respects I agree, but if you do that, this is just going to be taken down. So I’m asking a serious question. Has ASR actually changed your opinion on anything? For me, I would say 2 things. I am a conservatory-trained musician and I do trust my ears. But ASR has reminded me to double check my opinions on a piece of gear to make sure I’m not imagining improvements. Not to get into double blind testing, but just to keep in mind that the brain can be fooled and make doubly sure that I’m hearing what I think I’m hearing. The second is power conditioning. I went from an expensive box back to my wiremold and I really don’t think I can hear a difference. I think that now that I understand the engineering behind AC use in an audio component, I am not convinced that power conditioning affects the component output. I think.
So please resist the urge to pile on. I think this could be a worthwhile discussion if that’s possible anymore. I hope it is.
What the audiologist does is exactly that: whether a signal can be detected under the conditions of the test. They even play noise and then a tone to see if you can hear one over the other. Seems like you have neither taken an audiologist test, nor an ABX. As to multiple trials, that is exactly what I showed. Each row represents a randomization of the samples and you are asked the question again:
Above, the test was repeated 19 times and I got 17 right making the probability that I was guessing less than 0.0%. As to multiple listeners, that is if we want to establish detection thresholds for a population. In the case of a personal challenge, if you pass a test like above, it is a significant factor that calls for standing up and paying attention. This is orthogonal to what an ABX test is. So no, there is no confusion here. @kevn said he passed the test of high-res vs CD but provided no evidence whatsoever. And the test that he said he did run, is not about high-res vs CD. For my part, I took whatever challenges were common at the time and ran the in a proper program to see if I could tell the difference. Have you taken an ABX test and if so, can you post the outcome of any? |
Meaning what exactly? When someone here says DAC A sounds great and DAC B sounds like crap, how is that not a claim made under his test conditions? Heck, you don't even know his test conditions. At least with ABX tests, we have a protocol and way of documenting the results as I have been showing. If you are saying someone can create a test where you can't tell the difference even if an audible difference exists, that is a truism. This is why we have specification such as ITU BS1116 on what a proper test is. The issue is that audiophiles as a whole are terrible as a group in detecting small differences. This is why @soundfield is so confident that anyone saying or even showing the result of passing such tests must be lying or cheating. As I have explained, we have a responsibility to create a proper test and give listeners every chance to pass a test, not work hard to make sure they don't. Before you say ABX tests make it hard, well, I am showing you that I can pass them. So that is not a valid excuse if you are really hearing what you are claiming. Really, audiophiles routinely claim that making a tweak to their system makes a night and day difference. So much so that the wife in the kitchen hears it as well. If so, it should be walk in the part to pass the same in ABX test. If you can't with identical stimulus do that, then you need to learn why your sighted test was faulty. Don't go looking for problems in such a blind test. |
This is a bunch of nebulous claims. I don’t know what you have seen. What was hard about it. Or how it generated worst results than sighted. Such claims have been examined. For example audiophiles claim they need long term testing vs short. Clark led such a study for his local audiophile group by creating a black box that generated X amount of distortion. Audiophiles took these home but could not hear the distortion. Yet, another group with an ABX box and quick switching, not only detected that difference but eve a lower one! See my digest of that paper here. AES Paper Digest: Sensitivity and Reliability of ABX Blind Testing
See how I provide specifics to back what I say? Why do you think mere claims should be sufficient otherwise? |
I see where you got confused. Almost all of the ASR video content has the analyzer in the background. None of these tests were run during that video. Every test I have been showing predate my youtube channel by 5 or more years (see the dates in ABX tests and the ones for videos). In the video, I am just showing the results, not running them then. This should have been quite obvious. As such, your claim that I had an analyzer running at the same time of the ABX testing is totally false. |
