upturning the carts of the disc changers

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

LAZY_TITLE

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 this 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"

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

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

allows you to pick the appropriate words from today's paper

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

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.

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

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


@ LAZY_TITLE

...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: LAZY_TITLE

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

...but i'm there because, like

~ here is 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 DAT Tape can store 1.3GB.

~ and here is some gearhead saying you can get 1.5mb
onto a tape but only if you jam tin foil into it
[???]

~ DAT/DDS gets to 1.3GB because of better
equipment on both ends. helical scan 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..

~ data hiding in MP3 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]

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

oh lovely

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

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.
