Nice try but no cigar...

I check in periodically but am too busy listening to music or working and seem to keep seeing the same old arguments when I log in, there haven't been any good Jitter threads in ....ages...

  I have a question for you re checksums but I'll do it via PM , though not sure my students will like being told that TCP is not really reliable after all but it will make for a killer question for their final..

  yep, TCP when you absolutely 100% have to get every bit correct EVENTUALLY but it is generally considered too sloooooooooooooooow for "real-time" applications. I did a quick search and could not find any **canonical** (or reputable) source suggesting that Audio Over Ethernet implements...

  Not Ethernet though, Ethernet is not "reliable" in the strictest sense of the word. If you want guaranteed reliability with Ethernet you have to implement it elsewhere, duff frames just get thrown away, in fairness it is typically much more reliable than 802.11 but not without problems...

    People can be wholly honourable and honest (as they see the truth) and still be mistaken. This is not a new concept. People can believe they hear obvious differences even when no change in stimulus has taken place, again not a new thing. People can have their perceptions biased by all...

  The study I was referring to is from 1998   Theoretical and Audible Effects of Jitter on Digital Audio Quality Eric Benjamin and Benjamin Gannon Dolby Laboratories Inc. San Francisco, CA 94103-4813, USA   Published by the AES ...It was at the time the best attempt to define Jitter...

  Were you one of Benjamin and Gannon's subjects - cool !

  Interesting, how did you get such a wonderous jitter inducer and how much jitter was audible to you ? I've never owned even a cheap device where I suspected jitter to be an issue. But if you really want possibly audible jitter you need to spend a lot of money..McIntosh Jitter

  Dunn's papers are very informative and definitely worth reading, the only thing that his and Hawksford's (also highly readable) papers lack is that, they do not address audibility of jitter except as a mathematical model based on rather extreme sound pressure levels. To date we have little...

    Several already discounted papers appear in the meta--analysis inc papers from Meridian who are not agenda free, first 4 citations are papers written before High def even existed. Pras is dubious at best, since the successes were failures (more wrong than right by chance but significant...

Hydrogen Audio has a few threads about this including one where at least one "objectivist" has confirmed a verifiable ability to detect phase inversion, but as already mentioned you can do phase inversion in Audacity and test yourself

    The inversion seems okay in Audacity - the inverted and non-inverted files have the same FR spectra the problem seems to be with the act of adding the inverted and non-inverted files and then exporting the result which has the residual grunty - but since we have the 1000x FLAC/WAV result...

    I've had problems with Diffmaker in the past where two copies of the exact same file do not null correctly (ymmv) - I worked out that the alignment was not perfect .   With Audacity (for me on my system with my files) even two copies of the **same** 16/44.1 file with one inverted do not...

  I used Audacity to get the spectrum analyses - the output data was exported to text files and loaded and compared using Excel. I tried a few diff ffa - 4k and 16K and the differences were always 0   such as  

I did the whole WAV0 to WAV5 thing via FLAC0, FLAC1 FLAC2....   I checked the fr spectrum on WAV0 and WAV5  - identical to 6 decimal places - differences in each freq bucket 0.000000 - FLAC5 and WAV0 same result   For conversion I used an ancient FLAC frontend

    From article Quote:   I read this that listeners estimated the image height and this estimation was measured not that the speakers themselves were elevated and that the image height estimated by listeners was a proxy for sound quality I see no description that suggests that listeners...

    Having gone through Wav0 (original wav)  convert to Flac0 then reconvert Flac0 to WAV1 then reconvert Wav1 to FLAC1........... Wav5 and FLAC5 - if WAV0 and WAV5 are different in terms of the PCM content then ye olde DBT should work fine to see if listeners can hear a difference.   But as...

  And one which traditional DBT could easily verify or not - can you tell the difference between wav0 and wav5 reliably say 12/15 times - trivial and can be self-administered

    Actually it is pretty weak science. It is single blind which is normally considered a **terminal** error for any such tests and secondly there is no actual A/B comparison whatsoever just a sequence of signals so no requirement to be able to detect different/same. The proxy measurement is...

    Do you have any credible evidence for audible differences in cables , beyond those that are clearly faulty or deliberately designed to do nasty things to sound ?   I have trawled the AES and other places and have only found one peer reviewed paper suggesting an audible difference between...

  There have been few what you might call "scientific" studies testing whether short-term exposure (a few seconds) is better than long term (unlimited) and even less that I have seen would pass muster (imho) in peer reviewed journals or recognized conferences (I review papers as papers of my...

    Nope, you made an assertion, were does that assertion come from ?   You said we -KNOW (emphasis added)  you have to back this up, how do we know? what is the source of this certainty or is it just your opinion or folk wisdom?   Stop deflecting, it's okay to have an opinion (I think) as...
