can anyone suggest an example release, for which one could purchase both a vinyl and a direct-download FLAC that... the vinyl is 100% pressed from exactly the digital download, same source so i can buy both, put my finger on the turntable, and try my theories out? i guess i'd also need a turntable |
||||||||
|
|
|||||||||
| |||||||||
|
|
i guess it's also important to say while i have all manners of words for those who blindly hump crusty old analog formats, i firmly accept turntables as a legitimate instrument. |

...and it was somewhere between ansel adams prescribing breathing exercises and physical exercise routines to hold the camera more steady, and DJ AM that failed thread emerged. somewhere in my bullshit thread, the word "bionic" -- i'd just seen a DJ AM docu on TV and one of the guys on there was like: "he was, you know, as good as anyone else really... then he just disappeared for a while, and when he came back... he'd freaking gone bionic" |

anyways, it's here, i can do this, i'm not posting more details because it's funnier to watch someone else try it and fail than it is to write up instructions for someone to steal |

VinylFS the first unix filesystem specifically for vinyl data records |

a filesystem for vinyl data records, i am... what's the ginger word? chuffed? because this is the most awful thing i've come up with, like... all week that this is going beyond transmitting one data file. this is being able to mount a FLAC rip of a vinyl like you would a disk image. so it could contain multiple files, directories, etc will this ever happen? sadly, probably not. but if it is at all possible, i want to be there in the thick of it |

if you know all that then you know your stupid idea won't work. for the last time i never said anything about wav. i said "why would you compress the audio with flac before pressing?" you're the guy that used 128kbps mp3s until yesterday lol. stop pretending |

is there any existing work on the shannon limit, if both parties posess shared information? essentially, the idea being "context." and if we've agreed that the data sent corresponds to words in today's newspaper than 1 bit could actually mean more than one bit? i can't find anything on it |
||||||||
|
|
|||||||||
| |||||||||
|
|
probably a baliwick issue like, "you're still transmitting the same number of bits, shannon DGAF what you do wit 'em" |
||||||||
|
|

|
|
but. but. the context of shared language across humanity allows you to pick the appropriate words from today's paper -- even if you have to get creative -- and thus compress... ouch. my hed |

if you know all that then you know your stupid idea won't work. very convenient of you to be so sure, yet provide absolutely no details as to why you can translate 1 bit per side easy. is it a noise floor or maxed-out white noise? 2 bits? just split the playtime up and in the end, it's about "how far can you push this" and i don't think 50mb per side as a worst case is far off at all. with the theoretical capacity being much larger, but we've thrown most of it into sync/CRC etc you're the guy that used 128kbps mp3s until yesterday lol. stop pretending what i do not know is what the fuck you're talking about? i use 128kbps mp3s? huh? i haven't exported one of those in... actually, yes, at least a decade conclusions: mermaidman's trolling is off before he's had his morning cocaine. |

The 116 images (one used for calibration) are encoded in analogue form and composed of 512 vertical lines. The remainder of the record is audio, designed to be played at 16+2⁄3 revolutions per minute. Jimmy Iovine, who was still early in his career as a music producer, served as sound engineer for the project at the recommendation of John Lennon, who was contacted to contribute but was unable to take part. serato is 15 or 20 years old. here it is at 45 years ago |

really, this comes down to gathering the right bits from a few different fields. from the voyager golden record, i get: The 116 images (one used for calibration) ...and, why, yes. that's self-obvious, in retrospect. you have a dedicated calibration stage at the start of the recording to compensate for both speed and frequency response |

oh, it's not about that if sending out data in the format of an LP was good enough to put onto both the voyager probes and send further than any human-made thingy has ever been... then i'm on solid ground |

so for VinylFS i'm thinking you want to have a second volume in the ultrasound range so someone with crap consumer gear can open the first in the audible range... but people with better ATD can get at the second batch of files |

i have found CERTIFIED PROOF that i'm actually quite reasonable. because look at this insanity: The Kansas City Standard is a way of storing data and computer software on cassette tapes. Back in 1975 a bunch of guys (among others Bill Gates - long before being famous) met in Kansas City to try to define a common standard for data storage on tape. The result was a 300 bps FSK modulation scheme. For fun I will make a circuit that will take the audio from a cassette tape (or more likely a audio file from a cellphone), decode the audio into a digital serial bit stream and then convert this serial data into a parallel data byte onto a 7-segment display. Just to make it a bit more challenging I will not use any microcontroller or even any integrated circuits @ ...and i know people that do this sort of thing, like BUILD AN ENTIRE COMPUTER FROM DISCRETE COMPONENTS ~ that is, a computer, no chips it is some form of mental illness, you'd think -- but it's therapy for OCD people, and then many people just find it kind of meditative like cross-stitch really, however ~ what do you wind up with? the useless crap in his demo vid: it just sits on a shelf, i imagine, and occasionally he shows it off. then someone asks, "What's KCS?" and this is not even something you can show off because it's too conceptually dense instead my thing is more: "most vinyl is pressed from computer files, the difference is largely psychological, so i've pressed the ACTUAL computer file to the vinyl record to cut out the middleman" and then they can ask "so what's the point of vinyl then?" and i can say "EXACTLY" like, i have a point to make, normal people will get it, and this makes it art instead of a sad hobby 8-bit construction set |

...but i'm there because, like ~ there is a very good read of an explain on how tape data works here before it gets into the actual code, which is assembly language ~ meanwhile, other end a 60m/2h 1.3GB. ~ and some gearhead saying you can get 1.5mb onto a tape but only if you jam tin foil into it [???] ~ DAT/ gets to 1.3GB because of better equipment on both ends. like VCRs [i could look up ADAT, now, but i'd rather shove nails up my anus than even think about ADAT] ~ that covers that arc, right? existing attempts at vinyl data are pretty much within all that. but KCS only goes up to like 2kHz we can do more ~ so, um... oh! STEGANOGRAPHY. this has to be solved, because someone would definitely, um, oh, like.. ~ based on Huffman table transformation ~ GNU radio there's so much more tho |

when i SDIY custom music gear, it usually comes from me reading over some schematic, and "i could glue this part of this schematic into that part of that schematic i read SIX MONTHS AGO; that would work great" [and the agony of my life is my brain is completely right, but IT'S A LOT OF WORK TO BUILD IT] VinylFS, right. i'm not claiming to be some genius at complex analysis. in fact, thus far, i've avoided having to really do any of it [GNU Radio does that]. i am claiming to be a genius at mining fourteen different fields like a magpie, with a dash of Feynman's "do you have a map of that cat?" [Feynman won the bet] |

~ ...and when they stopped being able to push DDS (DAT) tapes any further with capacity, they switched to , they can get 160 gig onto that ~ they were gunning for 300GB but then someone at HP cancelled the project [did u noe: this is fun to research ? shit like this cracks me up] |

In many contexts, a discrete time (DT) system is really part of a larger continuous time (CT) system. For example, a digital recording system takes an analog sound, digitizes it, possibly processes the digital signals, and plays back an analog sound for people to listen to. ...so: digital is technically a temporary bubble inside of analog, and everyone can stop arguing now |

if you know all that then you know your stupid idea won't work. why not? i mean, really... why not? the answer to the sync issue is: serato has a strong sine wave throughout, and this it enough for it to determine not only speed, but direction -- so more than we need. the timecode stamps are to let it know where it is on the record; we don't need that either. so all we need to solve the fucking wobbly turntable problem is about 1/5 of 20yo technology is this hard? fuck yes. but, can it be made to work? i still have not found any reason that screams "no." i'm open to there being something that slams the door on it i've yet to find, but for the moment, i lean towards ~MERMAID.MAN.IS.FULL.OF.SHIT~ CDMA is not too bad. QAM though, getting like: THE CALCULUS, IT BURNS. then these things are just generic tools, all of them, and they stack. CDMA QAM and a punchy sine wav for time sync. have AE heard of "Manchester Code" ? that's a "self-clocking signal" but a waste of bandwidth if throwing a dedicated chunk of the spectrum to a sine wave will do i've come up with some intermediate stunts that don't require shelling out for vinyl. stay tuned |

. clocking, ok? get your mind out of the vinyl cutter solves the wobbly problem and gets shafted by the dutch over patents ms.pinky explains sine waves and what nosegrease does to timecode |

in the shortest way possible -- e.g. written by someone not me -- "Records are stereo devices and can encode two channels of audio (left and right). The pilot tone is printed onto the record with the left and right channels 90-degrees out-of-phase. When the record plays forward, the right channel will be 90-degrees ahead of the left channel. When the record plays backwards, the right channel will be 90-degrees behind the left channel." |

|
|
my magpie senses tho The two carrier waves are of the same frequency and are out of phase with each other by 90°, a condition known as orthogonality or quadrature. -- |

i contact the ‘inventors’ of final scratch, a dutch company called N2IT. i’m interested to know if N2IT are intending to try and patent their system, as our projects are so similar. i refer them to the spacedeck project website and they confirm that they have filed a patent application. they did not seem willing to discuss much else. i also send messages to richie hawtin/plus 8 records, who appear to have some kind of business relationship/sponsorship deal going with N2IT. no response from them. ...and with a shaved head, he's a dead ringer for some rat that shafted me over a place i worked years ago. he might need to go on santa's naughty list but that's a tangent |

wtf are you talking about? how is any of this answering my question you don't know. it wasn't. welcome to my personal version of "not now, the adults are busy, go play" what do you mean with "if you use your 96k sampling rate gear, you can stuff at most perhaps 300mb onto a stereo vinyl" this means you can use the same equations electrical engineers use to compute how much data you can stuff through a cable modem wire (analog, noisy) to napkin math the theoretical maximum data capacity of a vinyl record [sidebored ~ arguing with the "theoretical maximum" is arguing with claude shannon, and you don't want to fuck with that cat. i certainly got scratched badly last i tried] the factors are... [two] channels, [96k] sampling rate, duration of a vinyl record, signal to noise ratio of the channel(s)... e.g. the BANDWIDTH of a vinyl record i began by stealing someone's calculation off reddit, realizing they'd gotten the length of a record wrong, and then if we went up to 96k... then... not merely round down, but lop a chunk off the top, because that's life, and 300 is an easier number to remember than... i dunno, 350-something and this is perfect conditions. so we need redundancy. error correction. but, really -- 50mb out of this crate, and that's a success to me. particularly if you can claim "the world's first filesystem for vinyl records" and post cheeky merge requests to the linux kernel so this can all get some publicity. for me does that answer your question? |

WHAT ARE YOU ON ABOUT what does it have to do with dubplates ????? obviously this will take a couple stabs to implement [or, well, rat's fart chance that it won't]. so we need to press it and see if the computer can hear it. and how much we lose then, i dunno, are we going to be doing a full-scale run of this anyways? if you meant the thread title: marketing told me dub plates sell better than vinyl data |

personal log: for a brief moment at the end of august 2023, i actually got my head around quadrature amplitude modulation (QAM). it only lasted a few days, then work pulled us away, and when we got back to it a week later, we'd lost QAM. in april 2024, well, it's still not coming back immediately i mean the nuts-and-bolts implementation stuff. i still know the bullet points listing the features on the side of the box, where it's used in normal human life, and... well, i don't want to summarize gnu radio but QAM is what electrical engineers use to stuff data through a cable wire (analog, lossy). inside of QAM, we're now DIGITAL, and in here we have... redundancy and error correction [and then, finally, the world's first vinyl filesystem. for unix]. outside of QAM we lift most of serato/timecode discs to correct for the physical issues of vinyl [at the expensive of throwing away a whole channel -- it's worth it to not have to speed correct or whatnot] so [repeat entire sections across the record (timecode disc tech {QAM < convolutional encodingdatafilesystem i mean, i remember this stuff well enough, but... was it turbo codes? was i using them on this layer or that? how you structure the "container" -- using the word in a file-format sense -- very much up for debate and tinkering. the answer to "you're nuts" is "steal most of serato" and boom, stfu hataz. from there, i see QAM as the the unarguable winner to go from analog land to digital data ...but we could have it in redundant analog chunks ....and inside QAM the digital data has... blah blah it's very much a feel of building a PC at this level of design. going shopping for an analog modulation approach, and there's a sale on QAM, looks good "sale" in the sense of money=time and this one will save us quite a bit of time. for designing this probably never happening stuff. but, hey, i don't think anyone has the finesse to rip me off at least |

so i pulled up this thred, 'cos. in my bullshit thread, "oh, they aren't even numbers means... they're not _real numbers_ perhaps." leads to "when did we last touch complex analysis?" and my brain says this thread. and we pull it up. search thread for complex analysis: >i'm not claiming to be some genius at complex analysis. oh, get stuffed. i don't need any help with that i do need help with... a new job, actually. if this thread doesn't send you away screaming... it might work. like this whole concept, however -- the the idea of finding a job like this is likely to remain an abstract engineering exercise forever. and no, sam altman, i'm not working for you. stop calling me. even though i'm just making this up and imaging it i cannot describe how irritating it is |

do you think .htaccess is turing-complete? comparable question would be, "Can you build a functioning car out of duct tape?" ...can you do that? is that possible? [i lean towards no; powering it gets incredibly iffy] came up with this after reading magic: the gathering is turing-complete on lunch at work. if you allow a deliberately stacked deck, you can set up certain patterns of cards that force your opponent to perform computation for you. and there is a mathematical proof. that this "computer" can run any program any computer can. but you won't get very good framerates on doom ...a part of me promptly thought, challenge accepted and i'm promptly stewing on how to outdo this. in terms of, oh... AAAUGH YE GODS, WHY?! oh! i think .htaccess very well might be turing-complete" ...and this is sort of, like, you know. what i'm proposing with WHY?! because i don't think you can do any worse. in fact, i'm throwing down the gauntlet, here -- just try and outdo this level of... WHY?! the .htaccess idea is so beyond terrible; it beats this hands-down. but this vinyl thing, dub data -- this is the strange class of [AAAUGH YE GODS, WHY?!] where the technical quandaries are simply so charming and deep and wonderful that... wait, i'm still working on this? nevermind. it's wonderful |
