Your old records rescued. Brand new records made

In reply to "most" of the sane comments, so far today .. By Karl Brown.

Copyright: Since the "re-made" vinyl is a one off (not a quantity of "bootlegged" copies), for personal use, and not for general resale, in general (although of course there is a raft of possible interpretations of the letter of the law) the "copying" of the "original" reasonably falls within "fair use". There are some crazy provizo's regarding eventual and final "destruction" - you'll only find out about if you order !!!

Digital / vinyl contradiction. No, there's really no contradiction. You have in your hands and actually listen to vinyl. Yes of course there is a compromise in realistically having to dip into the digital domain (realistically, as that's the only feasible way to "clean up" the audio) which is one reason we only "go digital" once - in an effort to minimise any affects, which, compared to the very dynamic effects of the whole cutting process are pretty minute to start with. If you accept the fact that to "clean up" you have "make changes" and that they are only practically feasible in the digital domain, then the issue is one of necessary compromise, not contradiction. The alternative being, don't play your unenjoyable vinyl !

The "vinyl signature" double whammy, is another compromise. Can't do anything about that - signal originates on vinyl, and we want it back on vinyl. However, due (again) to the dynamic nature of the cut process, (which includes, every single analogue component, every bit of wire, the cutter head characteristics, the cutter amp, and the way it behaves in cohoots with the head, the stylus material, the "vinyl" material Etc, and even the mains quality (if you want to be pedantic)
the 2 "vinyl" signatures are bound to quite different - adding and subtracting to a "new" vinyl signature, further altered by the inherent "signature" of your playback deck, at least, if not entire playback system. We could all argue this one forever, but at the end of the day, if you have a beloved record in un playable nick, not available anywhere else (re master or 2nd hand) in good enough quality - we can give you something to enjoy. At, and in the analog domain, without digital "file" compression or brick wall high frequency filtering found in some digital formats. You, like many others so far, may also find you rather like our own "vinyl signature" - noted as "very musical" !

The "cutter" certainly is not a "classic" 40 or 50 year old Neumann, where the head dumps around half it's power in waste heat !. Technology has advanced !.
Actually, for those that didn't realise, there has been a micro climate of modern cutter engineers and kit manufacturers tirelessly producing vinyl and equipment for the "modern age" for many years. Specialising in materials and methods, to allow "one off" cuts to "hard" blanks which wear very similarly to a factory pressing. Among the innovations taken place:
Thanks to the aid of stronger magnets and modern coil winding materials and techniques, cutter heads are quite different and very much more capable than "classic" designs.
Thanks to modern plastic production possibilities, hard wearing blanks of a relatively hard surface (compared to the "classic" very soft lacquer surface) compare well to a factory pressed record.
Thanks to continual development by independent (not lathe manufacturer or their employes) engineers (like me!) on "classic" lathes, and later, modern units, "DIY" pitch controllers are far better than 40 or 50 year old designs. In fact, you'll be hard pushed to find even a late "classic" lathe like a VMS 70 that hasn't had a "SD" pitch controller mod.
Maybe you should be more concerned about the acceleration limiter !.

Cost.
Yep … undeniably but reassuringly expensive. The time taken is large, the cost of consumables (blanks and diamond styli) is large.
We predict around £ 80 for a double side album. Even at that level, we don't get "properly paid" - but that's fine, we are enthusiasts that would rather see something actually happen than not. Certainly I'd prefer to actually "rescue" some music than just talk about it.

Original record playback for digitisation.
The "Kickstarter" proposal - lets be clear here, is to financially aid THE MODIFICATION OF THE EXISTING LATHE and has nothing to do with the EXISTING (35 years in existence) studio, it's recording/reproducing equipment, vinyl reproduction equipment, monitoring systems, acoustic treatment or the building itself. Actually, we use a range of cartridges and styli. The "best" stylus/cartridge combination in the universe doesn't necessarily equate to "best signal V noise recovery".

To clarify, as succinctly as possible:

*One off actual cuts - not pressings (unless you want 350 copies - when copyright does definitely become an issue)
*To replace, in playable (surface noise and scratch wise) condition an other wise "un enjoyable" copy
*Cut to, specially developed 3 layer plastic blanks, offering wear characteristics similar to "factory pressings"
*Service for those that value a particular record enough to have a day to day playable version - unable to find a new release / 2nd hander of sufficient quality, and able to accept the compromises to get that playable & fully enjoyable copy.
 
I agree - the digital step will not be audible. But then they shouldn't talk about being able to avoid 'that inherent "digital" sound'.

It's going to sell into a market not concerned with such things.
To some the fact the music is on vinyl makes it automatically superior to a digital version, whatever the provenance of the vinyl. That's the market for this and you can't change their minds with argument.
 
"Extraordinary claims require extraordinary evidence".

Analogue is Analogue!!! It does not get any better than that. This is a fact and requires no extraordinary evidence.

Digital can only ever approximate to an analogue signal, it will never be the same. As soon as you digitise an analogue signal you are straight away introducing the limitations of the AtoD converter which includes the chipset, associated components and the power supply, plus any DtoA to play the signal back. All of this is now effecting the original signal to some extent. On a good system this will be clearly audible, as some on here have already experienced.

When you go to the Festival Hall to hear Beethoven or Mozart played by the LSO, that is analogue sound you are hearing. Similarly if you go to your local church and listen to the choir, that is analogue sound you are listening to. Sound is analogue. It's not digital !!!

And cucumbers are cucumbers. That is also a fact. That doesn't get any better.

And and analog signal can only ever approximate the original sound, it will never be the same. As soon as you transform an acoustic signal into an electric signal you are straight away introducing the limitations of the microphone and recording system, which includes transistors and opamps, associated components and the power supply, plus any power amps to play the signal back. All of this is now effecting the original signal to some extent. On a good system this will be clearly audible, as some on here have already experienced.

No, sound is actually digital. It is the motion of individual particles of air in quantum movements.
 
......and don't forget Tracing Distortion (mainly 3rd harmonic distortion) due to different styli shapes between cutter and reproducer..........

It's the analogue vibration of air, there is no sampling.

Quantum movement is within an electron and deals with particles moving in and out of different levels. The molecule as a whole moves in sympathy with vibration.
 
It's a sad day indeed when you've argued all other petty subjects to death you now have to argue the quantum mechanics of a sound wave or whether it's analogue or digital.
 
There really ought to be something like Godwins law for when the word quantum is used on a forum.

True. No sampling, just a conversion/representation, with all the errors that goes with that representation. In digital there is sampling and reconstruction, resulting in an analog wave. In a "pure analog" system, there is another form of analogous, but not entirely accurate, representation of the signal. It just happens that with the recording/reproduction systems available to use, the digitally performed analogy is closer to the original one than the purely analog domain one.

analog

(of a device or system) in which the value of a data item (such as time) is represented by a continuously variable physical quantity that can be measured (such as the shadow of a sundial)

You are right. My response was definitely a bad form of argumentum ad absurdum. BS is BS, be it quantum or analog.

The fact is that both "analog" and "digital" systems take an analog representation of the sound waves as their input, and produce an analog representation of the sound wave as their output. With currently available recording systems, the "digital" version corresponds more accurately and linearly to the input waveform.

You posted sound is digital in the air due to quantum stuff and that's utter bollocks, the above has nothing to do with your statement.

Sussed.....it's easy to quote wiki etc but one needs to understand it as well.

Indeed, as stated in the previous message, that was purely a bad form of argumentum ad absurdum.

So, both "analog" and "digital" are ways to represent (inaccurately) the original signal. Digital just happens to be more accurate most of the time.

I don't believe it, you are wrong and turn it around......credibility gone.
 
"If you think you understand quantum mechanics, you don't understand quantum mechanics."

A shame its not a real quote, it's too delish not to use here
 
Julf and Max just launch hand grenades into pfm and sit back and enjoy the ride, annoying to say the least;

Annoying if exploration of the subject matter isn't good for sales, or contradicts one's beliefs, you mean?

Max hasn't even heard a turntable and yet he knows digital is better.......blinkered.

Everybody knows that digital is technically better, that is a matter of fact, yet many, many people prefer the way vinyl sounds, which is another fact.

Whether I've heard it or not has no bearing on either fact.
 
For your delectation:

"The healthy cochlea is so sensitive that it can detect vibration with amplitude approaching the diameter of an atom and it can resolve time intervals down to 10µs "

" It has been calculated that the ear detects energy levels 100 fold lower than the energy of a single photon in the green wavelength "

So in a way we are down to the quantum-level.

And the electrical signals sent to the brain and detected by the hair cells only sample the analogue waveform at specific frequencies and thus is a discontinuous wave form.

At the end of the day sound like light is an illusion and we have no way of telling if we see and hear the same things in the same way inside our heads. We can only agree things like 'this note is an A' and 'this colour is green' and 'there is an awful lot of crap said on pfm'.

DV
