8. All members that put forth a statement concerning subjective sound quality, must -- to the best of their ability -- provide objective support for their claims. Acceptable means of support are double blind listening tests (ABX or ABC/HR) demonstrating that the member can discern a difference perceptually, together with a test sample to allow others to reproduce their findings. Graphs, non-blind listening tests, waveform difference comparisons, and so on, are not acceptable means of providing support.


I've read some of the linked discussion on TOS8 as well.

All of it covers objective vs subjective.

What IMHO needs clarification is the first phrase:

" All members that put forth a statement concerning subjective sound quality... "

Can a mod or admin clarify - in an official way - "put forth a statement" ?

For example, if I were to post "Joe Blow, the editor of AudiophileGuys magazine, says that the new Megabuck 9000 amplifier sounds better than any other amplifier", technically that would violate TOS8 - even though that Joe said that, is a fact that is easily substantiated by a reference to AudiophileGuys magazine web site. The statement is what someone said, not actually making a claim about audio.

Clearly, that is not the intent of TOS8. Rather it seems to me that the intent is with regards statements like "flac files always sound better than 320k MP3s" which would then need the substantiation required by TOS8.

Okay, then here is where the clarification is needed.

If I were to state in a post " In my setup, using ASIO output seems to sound better than WASAPI output. " - is that a violation of TOS8 ?

The discussion that TOS8 links to, suggests that TOS8 is designed to prevent statements of sound quality "fact" - as opposed to statements of personal observations. In other words, "ASIO always sounds better than WASAPI" is a TOS8 violation, while " In my setup, using ASIO output seems to sound better than WASAPI output " is just reporting an observation - and NOT an assertion of audio fact.

Am I correct, and is that how you would differentiate ?

Thanks.

My OpenOffice copy isn't able to open the provided document.

I don't really understand what you are saying. Are you talking about influences of HRTF and uh, I forgot the term for this, uhm, the influence of the room? tongue.gif

That seems to me to be completely irrelevant for showing a difference between two signals though. If both signals have been recorded under the exactly same circumstances, if there is any noteworthy difference in the waveform then that should mean that there is a notable difference caused by the different component or settings, no matter how much that signal gets distorted by physics. If physical effects would cause a difference of +5 dB at a certain frequency in one circumstance and -8 in the other, would not the very same differences be applied to the altered signal on top of the alteration, making the alteration still equally perceptable (if it is in the realm of perceptability at all of course, we could argue that no claims for this can earnestly be made below a certain point that is not relevant to the average listener, who is the one going to be influenced into purchasing the product after all) due to the preserved difference in both circumstances? This should be the case, otherwise even ABX testing in a specific circumstance could not provide the slightest hint of orientation for different circumstances either, and it'd probably mean that there are no general physical patterns to rely upon, which is evidently not the case.

Or is it the case that other factors are influenced that are not representable with a waveform? Wouldn't just providing the relevant measurements satisfy our needs then? If need be maybe all sorts of measurements that can possibly be made, even if that seems like a logistical nightmare to me where I'd rather conduct an ABX test. Of course, what I would prefer to do for my nerves' sake is not the matter here.
