History and Accreditation of ABX Testing/Invention?

History and Accreditation of ABX Testing/Invention For a while I have been curious as to origins of ABX testing. Reading forum posts, it would indicate Arny invented the scheme. You can see that from the post in the parallel thread and many quotes in AVS Forum: However the ASA was publishing a great many papers based on the JASA version of ABX long before the AES even mentioned the AES version of ABX. People who read journals and don't just drop their names know such things. They also know the nature of the differences between the two. One of the items in the committee review of Clark's AES ABX paper included clarifying these things because enough people in the AES knew about the ASA version of ABX whcih came much earlier. So did we. BTW the letters ABX in the AES were originally a play on my initials. Here are the examples from AVS Forum: For me, its about working to the highest possible standard. In the case of ABX, I invented the standard. And:[...] Arny Krueger has a degree in electrical engineering, has worked as a development and maintenance engineer in a number of areas of electronics, primarily IT and audio. He is the inventor of the ABX Comparator and did the first ABX test that was ever done. There are many instances like that. When I ask Arny exactly what invention means, I don’t get a clear answer. It may be just me so I thought I create this thread and see if we can get clarity on it once and for all. In the quote above, Arny talks about AES. The introduction to ABX testing was by a paper called 1982 paper: High-Resolution Subjective Testing Using a Double-Blind Comparator. Its sole author is David Clark. The only mention of Arny comes in this form: No read of this gives credence to Arny being an inventor of ABX test for audio. Their contributions seems to be building and popularizing the scheme for audio equipment testing which is great. But in no way could one call that effort an invention. If I build another alarm clock I would not call it an invention. The “prior art” is quite clear so by formal legal (patent) definition the invention is not one either. I am at a loss as to what AES version of ABX means. Or for that matter the “JAES” version that Arny mentions. Neither entity owns the work of the authors presenting papers and such. Arny, would you be so kind as to clarify your position in all of this? Do we have it right that ABX testing is 60+ years old and you had no role in inventing it? Thanks in advance.
