Hi, I have a question regarding TOS8.
I am wondering if TOS8 applies to *ANY* claim at all about audio. I am well aware of the need for ABX tests in codec quality testing, etc.
What I am completely uncertain about is the use of ABX tests and how it falls under TOS8 in regards to completely unrelated things to sound quality.

Eg. if a piece of audio had its pitch increased by 6 semitones. Is a ABX test needed to PROVE that such processing even happened?
Another example would be a phaser based effect with a minimum of 2 stages and a LFO frequency of at least 0.1Hz. Would it be a TOS8 violation to say that the sound has been processed, at all?

Thanks.

ABX tests are just one example of complying with TOS8: "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."

So your example has nothing to do with TOS8, as no disputable claim is being made. If still someone were to somehow argue that the pitch was not increased, there would be other objective methods of verifying that rather than an ABX test. For example, by making a spectrograph - which tends to be not acceptable is for audio quality discussions, but works just fine for this case.

Generally speaking, discussions here containing claims or things which are disputable should be open to scientific discussion and be falsifiable. A claim that cannot be verified or proven wrong is not helpful. Claims are easy to make ("Opinions are like as..."), but getting data isn't. Yet data is needed to understand and improve things.

Simplified, discussions here should preferably not be about "I think", "I believe", "I'm sure" or "I claim", but rather, "I have some data which seems to indicate...".
