Tracing Predistortion in Quadraphonic CD-4 and UD-4?

The thread on my JAES paper on tracing distortion got a bit hijacked by some semantic discussions ( https://www.lathetrolls.com/viewtopic.php?f=1&t=10062 ), so I am opening a new one. The JAES editor just sent me a "Comment on... "type of paper where the author pointed out an oversight on my part (D...

Re: Book "Electronics of Rock and Roll"

Received several private inquiries regarding the cost of the book. Prices can always be discussed, and we can all find various examples in favor of our views, but please note that the book is in large format (11x8.5 inches, the US letter format, close to A4 used elsewhere) and has 325 pages. It is a...

Re: New JAES paper on tracing distortions

this seems to be obsessing with what lacquers are called...this paper might have some interest back in the 70's ,but I don't think now... The problem here was that several well-established forum members felt the term "acetate" was so wrong that a correction should be published in JAES (which is not...

Re: New JAES paper on tracing distortions

Regarding the nomenclature, at least in the old times, ran into the "NAB Audio Recording and Reproducing Standards for Disk Recording and Reproducing" from 1964, available at https://www.richardhess.com/tape/history/NAB/NAB_Disc_Standard_1964_formatted_text_and_graphics.pdf . It includes a glossary ...

Re: New JAES paper on tracing distortions

For what it is worth, ran into this passage on https://www.rarerecords.net/record-info/acetates-and-test-pressings/ : "While acetate pressings are usually referred to by record sellers and collectors as 'acetates,' the term used to describe them within the industry is 'lacquers.' That term makes mor...

Re: New JAES paper on tracing distortions

Thanks for all the clarifications. I cannot change the terminology in the JAES paper, but I did it already in the latest version of the book ( https://www.amazon.com/Electronics-Rock-Roll-Electrnics-Enabled/dp/B0CR832NVZ ). As I mentioned already, the paper used "acetate" mainly because that was the...

Re: Book "Electronics of Rock and Roll"

A version with the black and white interior is also available now, see https://www.amazon.com/Electronics-Rock-Roll-Electrnics-Enabled/dp/B0CR832NVZ . I had to make it because Amazon could not sell the original one in Australia. Something related to color interior and glossy vs. matt finish that is ...

Re: New JAES paper on tracing distortions

On second thought, I would actually encourage you to submit a “Comment” paper to JAES. I am still not sure that this problem is important enough -- some readers might think we are splitting hairs -- but it could help bring some attention to the paper and show that people still read and care about th...

Re: New JAES paper on tracing distortions

you should change that word in your interesting paper to 'lacquer' Thanks for your comment, boogievan. I understood that AussieOsborn’s rationale was that the “lacquer” should be used because there is no acetate in it, and I documented that the term “acetate disk” was used in the JAES as an alterna...

Re: New JAES paper on tracing distortions

We all seem to agree with "Wikipedia" that lacquer disks have not been made of acetate since the late 1950s, but as far as I can remember, the term "acetate disk" continued to be used regularly in the industry despite not being correct chemically. From the mid-70s to maybe late 80s, while I was in c...

Re: JAES paper or distortions due to lateral tracking error

Sounds useful! Hope AES's research yields fruit and brings this old issue to light! It already created some further research. Peet Hickman published "Analysis of Löfgren's Tonearm Optimization" in the Jan. 2023 issue of JAES, see https://www.aes.org/e-lib/browse.cfm?elib=22031 . Unfortunately, this...

Re: New JAES paper on tracing distortions

It just occurred to me that this might be the first paper in the “Journal of Audio Engineering Society” to reference a document from the “Secret Society of Lathe Trolls” website (reference [57]). A search in the AES library (https://www.aes.org/e-lib/) seems to confirm that this is the case.

Re: New JAES paper on tracing distortions

I look forward to reading that in full. Bear in mind that there is no acetate in a lacquer disc. We generally refer to the cutting stylus as "cutting stylus" rather than a "chisel" and a lacquer disc as a "lacquer disc" rather than "an acetate disc". Again, there is no acetate in anyting we use and...
