hey everbody

i made a new video. it's about how stereo sound works on vinyl records.

please provide me with positive reinforcement for holding back on chastising the youngins for continuing to call records "vinyls"

also please never ever do that you heathens

anyway, here's the linky-dink (i'm giving you, like, 10 minutes early access!)

How do vinyl records hold stereo sound?

YouTube
@TechConnectify Why does it say "unlisted?"
@rubbs because of that 10 minutes of early access I'm giving you (which turned out to be around four)
@TechConnectify Ah, that's good enough for me! Thanks. Also, I immensely enjoy your videos. I'm a software engineer by training, so I appreciate and understand your engineering approach, but in a brand new context! So thanks!
@TechConnectify @rubbs Mastadon early access! Its like patreon early access but you get what pay for. 😆
@TechConnectify I've stopped caring. The vernacular has changed.

@hunterking I'm becoming less prescriptivist as I age but this one MAKES NO FUCKING SENSE because "vinyl" is a /material/ and not all records are vinyl!

Besides just that, it's like calling a pair of jeans "a denim" or your computer a "personal"

I'm OK with saying "I have that on vinyl" but the thing itself is not a vinyl. It is a record, and I will unendingly grumble about this at least in my head.

@TechConnectify ok I do think you're fighting the better fight.

The "plural of vinyl is vinyl" attitude feels misguided to me. "Listen to this vinyl I found at a garage sale" still sounds stupid, and most people I know that collected records before the revival just called them records.

@hunterking

@TechConnectify

The funny thing to me is that this is a silly example of a point I mostly agree with you about.

There are two kinds of nouns in English. It seems there's a few different things you could call them, but I call them "mass" and "count". "Vinyl" the material is a mass noun, and doesn't become plural when you have more of it. "Record" is a count noun, and does become plural.

"This" applies to both, though. Check it out: "This water is clean." "This cat is fluffy."

@TechConnectify @hunterking a few other examples are "a steel" (the tool for honing a kitchen knife) "a rubber" (perhaps slightly dated). Might be interesting to find out if a linguist knows whether there's any regularity to when speakers produce shortenings like this -- often the answer is surprising!

@punster @TechConnectify @hunterking "rubber" could refer to either an "eraser" (US english term) or a condom (i forget if rubber is also used in US english, IIRC it is in UK english for a condom)

i am very bad at phrasing things

though people don't call a knife a "steel" unless they got a great deal (ha)

@spv @TechConnectify @hunterking it's the honing rod, not the knife itself, that people call "a steel". That leads to this kind of funny example of a "ceramic steel": https://www.chefsarmoury.com/products/chefs-armoury-10-black-ceramic-steel

There's also an iron, the clothing tool, which generally isn't even made of iron any more!

@punster @TechConnectify @hunterking i didn't think about an iron! good point
@TechConnectify @hunterking reminder that you americans call it gas when it's a liquid. one to talk, eh? ;P
@Riedler @TechConnectify @hunterking
I agree, but I think it is a diminutive for gasoline

@Riedler @TechConnectify @hunterking

#pedantry it's the vapor that burns and provides the motion.

Also it's a shortening of "gasoline" afaik.

@TechConnectify @hunterking Back in the early 90s, I was in a record shop (a place where you bought music but didn't actually have any records) and asked for a particular album.

The clerk laughed and laughed at the word "album" because they only had cds, not "albums", not understanding that an album is a collection of items and not its physical form.

@mikej @TechConnectify I've definitely seen "record albums" thrown around by older people advertising garage sales.

It's kind of fun how this stuff happens, like how VCRs have somehow become "VHS players"

@hunterking @TechConnectify In addition to record albums, there are "photo albums".

When referring to music, "album" feels the most form agnostic. Vinyl, CD, mp3, tape, as long as it is an associated collection of "tracks" (another potentially troublesome word.)

@TechConnectify as some one getting into records for the first time since childhood, I’ll be calling them “vinyls”, “records”, and “vinyl records” with wild variability.

@RC The last two are perfectly acceptable! And you may refer to your collection as "vinyl" without my daggers of judgment.

But if you choose to call an individual record a "vinyl" I must insist that all of your clothing items now be called, simply, "a cotton," "a denim," "a polyester blend," etc.

@TechConnectify @RC referring to articles of clothing by their materials sounds kinda awesome

@TechConnectify I get the irritation. I cannot stand people calling a single analog number randomizer made of plastic, wood, bone, or similar material “a dice”. It’s a die and I feel personally attacked as a game designer that “a dice” is becoming more accepted.

But, language evolves…. I’ll still be calling a die a die in any ruleset I write though.

@RC I would like the... record... to state that I am similarly irritated with die/dice. I knew that from a very early age and am not sure how that got lost.
@TechConnectify That seems to be in line with your particular brand of pedantry (which I love, btw).

@TechConnectify @RC

In french I still get irritated by the words
"key" -> "Clef"
and "wrench" -> "Clé"
Both are pronounced "clay"
But people were miss-spelling "clef" so much that it became accepted that a key is "clé" and a wrench is also "clé"
So the word change out of ignorance... Is that progress?

@TechConnectify i only listen to music on shellacs
@TechConnectify great. I saw the word “vinyls”, and the first thing that popped into my head was that song by the Divinyls, and now it’s stuck in there. You know the one.

@TechConnectify I'm going to break out my collection of polycarbonates to listen to some high-fi music.

Just kidding. I'm 37 and I've never bought a music CD.

@TechConnectify do you prefer 'vinyl record phonograph platter'?

@TechConnectify
I'd vaguely known that the stereo whatsits were stored as the difference between the left and right channels, but I wasn't aware that 'decoding' was as simple as having two pickups at opposing 45 degrees to the record groove.

Analogue circuitry shenanigans? Nope - basically mechanical!

Clever, innit.

@coprolite9000 @TechConnectify Part of the cleverness by using a 45° offset, is the sideways movement will have opposing phase at the pickup. As the stylus moves side to side, one side moves in while the other moves out. To make this mono, you invert one side before you play back the L/R signals. But up and down motion results in both sides moving in or out simultaneously. Because you already have to invert one side, that “stereo difference” gets applied inversely to each channel.
@coprolite9000 @TechConnectify additionally, lower frequency sounds tend to be centered in the mix to increase impact, and therefore the stereo difference channel will not contain these lower frequencies (cancelled out). This reduces the likelihood of the stylus to skip out of the groove. (There’s other things happening here as well, like the RIAA EQ curve)
@TechConnectify I'd love a video about quadraphonic records some day.

@TechConnectify hello, young person here: I consider vinyl to be like an uncountable plural of records. Trees:forest::records:vinyl. Also “I have it on vinyl” similar to “I have it on disc”. And I mean, technically, CDs are records too. (And vinyl records are discs!) Words tend to get fuzzy around music because people are too busy jamming to correct each other, and I respect that lol, wish I had such a good time

Thanks for video btw

@TechConnectify
Looking forward to this. I been wondering for a long time how that worked

@TechConnectify perhaps us in non-english speaking countries can be excused. For example in Finnish there is no specific word for "record" - we just call them discs.

CD's are also discs so we started calling records vinyls when CD's became a thing. Sorry.

@TechConnectify I don't think you used the word(s) wiggly/wiggles/wiggling enough

@TechConnectify There were technically three choices, given the raw material PVC. "Polys" sounds a bit too strange for an audio format.

And i'm not sure if "borrowing some of your Chlorides" had ever a chance of catching on outside the chemistry student community.

@TechConnectify hooray for mid-side encoding!
@TechConnectify you should do one about the audio tracks on cinema film. The fact that they can fit analog, dolby digital, dts and sdds on one film print is fucking amazing.

@TechConnectify Good video. joint encoding is not a technique that has left us for lower bitrates

https://en.wikipedia.org/wiki/Joint_encoding

Joint encoding - Wikipedia

@garethklose Do you happen to know if any AAC encoders allow disabling joint stereo (or the “instensity” variant) in the encoder settings, as most MP3 encoders do?
@whophd no idea. Was that a thing?
@garethklose in the lame encoder and other MP3 implementations, absolutely. I had someone ask me about AAC recently and I couldn’t find the documentation though. They said joint encoding always impacted AAC and I said “not necessarily” and they said “well you can’t disable it” and I was 🤔🤔😓

@TechConnectify whenever I upload a new record to YouTube I include the tag vinyl because that’s what they call it these days and I want to make sure it gets picked up by the algorithm.

Anyways, shameless plug:

@TechConnectify williams pinball shirt!! what's your favorite williams pin?
@TechConnectify I need to do a longer one about how stereo FM broadcasts work! That one is truly head-asplode worthy to nerds who haven’t thought about it
@kirkman @TechConnectify I once had a vintage vacuum tube demultiplexer that sounded amazing. Miss that thing.
@stormdig @TechConnectify How about this vintage Inovonics 530 off-air modulation monitor? It doesn’t handle HD Radio broadcasts very well, but it’s still cool to look at.
@kirkman @TechConnectify love that style. Reminds me of a 1980's Technics receiver I used to have.
@TechConnectify I've got this weird "Stereo Test Record" that contains audio test patterns, like a 800 Hz tone on the left channel combined with a 3000 Hz tone on the right, and you can clearly see the different frequencies on the left and right sides of the groove under a microscope: https://groverlab.org/hnbfpr/2019-08-06-stereo-records.html

@TechConnectify oh hey, you're on mastodon. I've been loving your videos for a few years now. I'm still beside myself that a fellow northern midwesterner uses a heat pump successfully.
