So confident was I that I could hear a difference between bit-identical replay, that I paid for your train ticket to demonstrate it to you. And I just happened to have got lucky?

fas42 Posted April 23, 2019 Share Posted April 23, 2019 Bit identical files will sound identical if the mechanism, and procedure for playing them is absolutely identical. Change that process in what seems a trivial aspect could be enough to have an impact - e.g. comparing A to B, there should be an equal weighting to playing A, then B; versus, playing B, then A. Time variant factors are a big part of hearing differences once setups are working to a certain level, and can be a nightmare to sort out, properly. There are obvious elements like how warmed up the speaker suspensions are, but just about every area of a rig can be sensitive to changes over time; unfortunately, right at the edge where sometimes it's hard to say what has changed - but, it is audible. sandyk 1 Link to comment

The files that I provided for the DBTs MUST have had some differences, or no differences would have been verified. DUH ! Clearly, the checksums are presently incapable of revealing the differences, just as they did with Mani's examples. You need to be able to capture in analogue form the actual digital streams to carefully examine them for differences, whether in the shape of the waveform or extraneous noise present with the data.

This has nothing to do with checksums. Once again, WAKE UP ! According to presently accepted theory, if they are identical when compared bit by bit to each other, then the checksums WILL be identical too. You need to do as I just suggested in my previous post. Forget the BINARY DATA checks and closely examine the actual digital stream waveforms.

That's all there is to say until substantial new information is obtained. Unfortunately, hauling my lab gear to your place isn't practical. Too bad. You took part and allowed the single test to proceed. It is no use now to cry that the methodology was invalid, especially when it was conducted by an objectivist. Frankly, I am now inclined to believe that under some controlled condition there could be some difference that may be audible for many of the things that supposedly outside human hearing threshold. And i emphasize again, “ controlled condition”. ST My Ambiophonics System with Virtual Concert Hall Ambience Link to comment
Ralf11 Posted April 24, 2019 Share Posted April 24, 2019 I am glad that both of the manxx people did this test. It is certainly a step in the right direction. And that is true even if manxx #1 got lucky, or if some bias was present besides SQ or if the files really did sound different. But if the files do have a different sound then that is an extraordinary result, and further investigation is needed. numlog 1 Link to comment
