That was fascinating, I’m gonna have to watch this a few more times, but I’ve always wondered how our record worked. Thank you very much.

Would you please say something about the so-called "oils" or "released agents" that supposedly remain on a record's surface and groove and that some say we should get rid of by any means?

Very cool

This is an amazing interview with Bill. I love his album and listen to it at least twice a week. I've been a fan of his since the 1990s, and this is indeed a unique treasure. Thanks for the upload.

Very nice..thank you for some great information on the process...really cool 😎

I wonder how a mix with vinyl in mind could optimize the results, but then, what’s the best deliverable and how much low-end can we pump in those grooves right 😊

Awesome. So i leave it to the experts.

Yah up yours Scott! How rude. 😁

If the thin depth of the copper plating is a drawback to DMM, is there a reason not to use a solid copper disc instead of plating? And, on a slightly different topic, has anyone successfully cut a master with a laser rather than a physical stylus?

I was curious, has anybody ever just made a random record where they just random grooves and seeing what the music came out to be

thank you for this video I'm doing a speech on something similar this helped a ton.

Do you have specs to share re: dynamic range and frequency roll off? i realize there are tolerances and other factors that cause variety. But generally speaking, is it possible to state generally what the difference is regarding frequency response and dynamic range with the two different types of vinyl master? lacquer seems appealing based on qualified statements i've heard from people....but some more objective info would helpful.

4:44 - On the original pressing of Aenima by Tool, the track "Useful Idiot" (itself the sound of a noisy repeating locked groove) not only continues into the locked groove of Side 1, it also resumes in the lead-in of Side 2, before the next song begins.

Great stuff!! It is amazing how MS works. My question is. How are the tones and overtones represented and reproduced?

Who you going to believe? Some guy who's been doing it for decades and owns the studio? Or an expert with their own RUclips channel, who's got their info from watching other experts on RUclips, and has no experience in the real world. I know who I'm taking advice from.

👍🏼

I have the 1980-ish Rhino LP of Henny Youngman which has 4 separate programs on the B side, so it's like a 5-sided LP! 😀

This is THE discussion ive wanted to see. But i think you arent really telling the truth. Because ive never seen a record surface that is "smoother" and looks like it has shallow grooves that has been loud. I have a two different 6 minute 12" records here cut in the 80s. One was cut in germany, the other in the US. The cutting guy on both had all the wax space in the world he could want. The US one just looks rougher on the surface...the grooves are deeper. And surprise surprise its waaayyy louder than the German one that has more of a mirrory surface. Hell i can even compare apples and apples with the same song (eg Madonna pressing) so you cant blame the "program material" and its obvious. Of coruse, whether is 180g plastic or 120g makes absolutely no difference to anything level or groove depth related. In summary...shiny, weak looking grooves SUCK. And i dont know why cutting engineers keep doin it....especially these days. Records made in the 80s had such stronger/deeper grooves. What the hell....

id like to see a discussion about the magical 22 minute per side limit. How many db does the level drop per extra minute over 22 minutes. Also id like to know about groove depth and why some cutting engineers simply wont cut the groove as deep as others, how that affects playing time and level...

The audience that clicked on this video is smarter than you think. You dont need to "dumb it down" ...was easy to understand.

How deep are the vynyl disk grooves?

and additional to all of this is the RIAA curve! And given the amplification needed, and potential for issues on playback alignment, it's amazing that it all works at all.

I have understand the different pressing versions of the record but never seen the metal before, so for that was interesting, thanks

Glad to see someone in the studio give us theirs thoughts and a bit more, appreciated

Did the vinyl makers finally decide to drop the stereo with mono compatibility groove cutting and just focus on the best stereo cutting, when the interest in mono playback went to almost nothing? If not, then why not? After all, the mono record enthusiasts prefer records cut specifically for mono playback only.

I made it to the end, and it was well worth it! Thank you!!!

That's why 33rpm can't make the groove as wide as the 45rpm's dose and that limit the sound quality and dynamic(also why Vinyl Bass sound only limit on center /mono)

Hi guys very interesting.. great monty python story.. I had matching tie and handkerchief and my automatic turntable missed the extra groove and I was unaware of it until I had a manual turntable and out the stylus onto the other groove accidentally

I've heard this explained many times but this is, by far, the most thorough and enthusiastic description. loved it to the end, thank you.

This was great. Thank you🙂

Awesome

My late dad used to repair TVs, radios, and stereos for people. He has a kit full of replacement needle cartridges. I am the only person I have ever known to own cassettes made by Pfanstiehl. (I had to pull one out of the drawer next to me to make sure I spelled it right.)

I spent the entire summer of 1983 after graduating babysitting two neighbor girls. The money I saved up bought me a $200 Sharp QT-78 Dual Cassette Portable Recorder. This had a "Stereo Wide" button that made FM sound even more dynamic. You can hear a couple of the songs I recorded get a richer sound all of a sudden because I forgot to have that button down before the song started.

Great explanation - like the FM example - sum and difference

Engineer here. Love a deep dive from someone who knows their stuff.

This was unexpected and deeply appreciated. What amazes me is how a record player, with all the electronics does the same thing as a plstic cup with a pin stuck through the bottom. The analog to the analog? Or vice versa.

And if you reverse the polarity on one channel of a stereo cartridge you can play old edison dimond disc records because there audio is in the bottom of the groove up and down instead of sode to side . You didn't mention that.

Got to the end, thoroughly enjoyed it! 😊

If it's not on CD, it's not for me!

Wow! Thanks for this brilliant explanation! No doubt I'll revisit this video at a later date. What amazingly elegant technology!

A side effect is that the bass drum/guitar/etc need to be pretty much mono centre, else the stylus is likely to be flung out of the groove.

I had an opportunity to work with one of the greatest recording pioneers in the business, Emory Cook. His was the idea behind 2 grooves on one disc, and two tonearms. It was called Binaural Recording and he had a great legal battle with Columbia over the application of stereo onto disc. Obviously Cook's method was too complex, contrived and limited to become the stereo standard. However his excellence in stereo recordings on reel tape is still widely regarded as the best and most faithful in capturing not only sound effects, but bands, orchestras and other music venues. He was, and still is, the smartest man I have ever met and it was an absolute honor to work with him. Google him. 😀

Well, it would seem to me, from THIS explanation anyway, that this gentleman has never heard of or has no idea of how the 19khz FM pilot signal works.

Groovy!!!

Fascinating - Cheers 😎

👍

I would like to hear more about the pre-emphasis at half speed. Is it simply a matter of doubling the time constants?

My amateur rig, a British lathe from the 50s, has a 66 2/3 rpm spindle. Time saving before quality was obviously someone's motto...

Yup, early digital (Sony dash mostly) and eighties DMM recordings sound bright and pointy and lack anything below 70hz. I never got the hype. But now that I know it was also a cost cutting measure I am starting to see how this went 😁. Thanks for the explanation!!

Fascinating so then the bedside microphone technique actually has its history in final records and goes back far far more than I thought. I think this is the first explanation that I run acrossed that really clearly explains what's going on.
