Return of the Vinyl Album
bulled writes "NPR ran a story this morning about the comeback of vinyl. It seems that sales of new vinyl records are up about 10%; sales will approach a million this year (as against half a billion for CDs). NPR mentioned the popularity of a turntable with a USB interface — they didn't specify the brand; could be this one, or this — and speculated on other possible reasons for the resurgence. They mentioned sound quality and lack of DRM as possible causes. Sound quality can and will be debated, but DRM rates a resounding 'Duh.'"
From a collector's stand point, vinyls never really faded from popularity. I still have all of my old vinyls and purchase new ones today by more current bands.
Didn't vinyl make a comeback about 12 or 15 years ago during the grunge era? What makes anyone think this is anything other than another small bump in popularity?
It just happens to be hip to own vinyl again, mainly due to "audiophile" acts like the White Stripes and Modest Mouse, and other hipster indie rockers wannabes.
This too shall pass.
record player with USB? doesn't that defeat the purpose of analog sound quality?
There's no debate. Analogue recordings are better. And they keep better too. If you make an analogue recording of something using top of the line equipment, 50 years from now, you'll be able to use superior tools to pull a more accurate representation of the sonic environment than anything we can do now. If you record digital, a bit is a bit is a bit.
Best method, use the highest quality analogue gear you can find to record, then sample it in the highest quality digital you can for editing and distribution, then throw the original analogue in the vault so you can re-sample it again in 5 years.
-1 Uncomfortable Truth
The social equivalent of tongue piercing. Once everyone goes digital it's fun to shock people by going analog. Plus scarcity creates value among collectors. One thing is true: vinyl will outlast CD in durability, and the error correction is much more robust on Analog.
Some drink at the fountain of knowledge. Others just gargle.
People are buying vinyl because it sounds better than digital recordings, and then using a USB turntable to make digital recordings of their vinyl records.
What am I missing?
I've always liked collecting vinyl for novelty reasons.. yea of course other types of media might *sound* better, but who cares.. I can buy a jazz record that I'd have a hard time finding on iTunes or some shit if it even exists on there, for $1 at a thrift shop instead.. that is priceless.. plus you own a piece of physical history.. the sound has never mattered to me.. caring about the sound is like only saying you'll listen to bands that record with ProTools and who are Auto-Tune trigger happy.. sometimes it's the music that matters.. the vinyl surpasses the value of a CD as a physical object.. hell, it lasts longer and the inserts and album art are 3 times the size.. 3 times the fun for me baby..
*plays the Apogee theme song music*
Surely you don't think they're going to put the raw analog signal right in the vinyl so you can copy it! They're not about to make that mistake again. A generation of USB-enabled record players will come out that will be able to play your vinyl records from the attic, and also some goofy "new and improved" vinyl hi-def format where you drop the needle on an encryption key instead of the first track.
Nothing less.
If someone could set up shop pressing 8-tracks, they'd sell too.. People collect 'em
12" records have nice art and look good on the wall, etc.
I don't need no instructions to know how to rock!!!!

While you may think I'm joking I note that a 30-40Kb/sec stream is more than suficient to store audio at near CD quality in real time. You can send 30-40Kb/sec over a telephone which has a small fraction of the bandwidth of a record. Thus I can actually encode about 8 simultaneous stereo streams
since audio records last about 40 minutes, 8 streams gives me 320 minutes of near CD quality music which is longer than an audio encoded CD can provide. Next up VCD on Vinyl

Copyright infringement isn't stealing.
It shouldn't even be a crime.
It's an obsolete social mechanism that causes more than enough harm to offset any socially redeeming qualities it has.
This imbalance between harm and benefit becomes greater as our technological capacities increase.
If you make any long term plans around copyright continuing to exist, you're a fool, because it's not going to.
-1 Uncomfortable Truth
What I thought was most remarkable was that this was not a technological breakthrough, we've been able to record turntables since PCs had sound cards, but that it was the packaging that caused this change. Most people simply aren't going to discover that they only need a program like Soundforge and a decent soundcard to do everything these packages do.
All it takes is removing a couple steps to make something extremely attractive to the consumer

One thing is true: vinyl will outlast CD in durability

One thing is true: vinyl will outlast CD in durability, and the error correction is much more robust on Analog.
I don't think so. the abuse a standard CD is subjected to would utterly destroy a record. how many people put a dozen naked Records on top of each other in a care that goe over bumps. 2 bumps and you have yourself a pile of useless plastic. I do the same to CD's and they last about a year with this abuse. Records last a long time now, because those who buy them treat them properly. CD's have finite lifespans because they are small, and versatile and thus often abused.
CD's and Records fail in different ways. A light scratch across the record will render every track with a regular periodic snap/pop or even render it unplayable. A light scratch on a CD may result in a bit of a skip or no data loss. A deep scratch on both results in an unplayable disc. Multiple light scratches on a CD will still often be playable and often without quality loss while the same for a Record renders it unplayable. Repeated play degrades a record, while it doesn't really degrade a CD. And Vinyl is not as mobile.
Also, You can back up a CD. You cannot back up a Record into the same format. Error correction on analog data is not more "robust" it's different. Critical failure on an anologue system is different then on digital. If I introduce random noise to a CD, I can digitally filter it out if I know how. The same type of error on a anologue signal might result in static. cleaning up such a systemic loss is hard on analogue. When the damage is mroe severe the digital may be unrecoverable while the analogue may still cary some of th edata. Digital has a recoverable area/damaged area rate that looks like a inverse log. 0-50% damage = 100% recover 50%+ = 0%. While Anaglogue has a linear decline.
"There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy."
There's another reason that no one has mentioned yet. More space for cover art.
Before you even concern yourself about the quality of any modern consumer electronics product with a well-known name, find out if that name is still worthy of its history. Many of the former greats in audio reproduction have sold out to Chinese manufacturers, sold their names, their brands, and the respect they earned in the marketplace. Now they're nothing more than marketing fronts, shadows of their former selves.
The higher the technology, the sharper that two-edged sword.
switch from MP3 to WMA so you can add DRM and I might be interested. But I'll have to wait for the Zune version so I can squirt my Vinyl. Chicks dig me.

If vinyl turntables (with USB, natch) used a laser pickup instead of a mechanical stylus, vinyl would be a lot more popular. Then records wouldn't wear out nearly as much. They could be sold used for more money with less damage. And a laser turntable could scan a record at high speed (maybe 333 1/3 RPM, 100x) for portable (lower-fi) playing on iPod, mobile phone, etc.
Laser pickups themselves wouldn't wear out like a stylus used to, which used to put the turntable out of commission until a new one was bought. Which was sometimes expensive, especially when the electromagnetic transducer cartridge needed repair/replacement. Those were expensive, especially the really hifi ones. Today, laser pickups would be cheaper than that old precision EM stuff. And they could still be analog, like an original videodisc, with audiophiles fighting over imperceptible differences in the analog/digital converter.
I'd get one. Vinyl sounded so much better at its best than any equivalent priced digital system I've ever heard. But then, I prefer to listen to music that was produced for vinyl's acoustic response. Kids today could get into it, too, though, if it really is a hybrid of phat old analog and cheap new digital.

Isn't Vinyl just Physical Rights Management? My car can play a burned CD, even one with MP3s or WMAs on it. I haven't seen a turn-table since I was like 4 (I'm only 21).
Not a Twitter sockpuppet... but I wish I was.
The last two records I bought on vinyl (the new records by Of Montreal and M. Ward) came with a coupon for one-time download of DRM-free MP3 versions of the album tracks from the label's Web sites. So I get the big cover art and the intangible experience (they're both double albums on vinyl) but I can still play 'em on the computer without sweating over the process of digitizing vinyl.
Fact is, the vinyl version of the Of Montreal record (which is awesome) has a scratch that makes track 3 repeat the same crazy groove over and over, and it sounds intentional and much, much better than the digital version, which now seems weirdly short. And it comes with four bonus tracks, which are included in the download too but not on the CD version. Obviously some small record labels are betting big on vinyl as a way to keep people buying records, and I'm all for it.
Some crazy Japanese company (Sony I believe) released a product called a "Compact Disc" Player (CD Player for short) in the early 80's that implements a scheme vaguely like what you describe. A laser pickup ("needle" if you will) runs over tracks ("grooves"), looking for divots on the surface.
I wonder whatever happened to it..
The copper bosses killed you, Joe. 'I never died', said he.
Well, an interesting thing happens when you compare CDs and vinyl records. Turns out that CDs do a much, much better job of reproducing the original recorded waveform than vinyl. I.e, for sound fidelity, CDs totally kill records. It's not even close.
Now the interesting part. It seems that humans don't really care about sound fidelity. They care about things sounding good, which is actually not the same thing. The vinyl records introduce a whole range of coloring distortions into the audio. This is made far worse by the noise reduction circuitry and lousy, thermally varient amplifiers (I'm talking to you, tube-amp owners). This radically changes the way the sound comes out (go ahead, compare the waveforms using an oscope). It also makes them softer, warmer, and generally more pleasant. The real world has a lot of harsh edges, ringing tones, and crackles that really don't sound too pleasing.
So, in conclusion, vinyl is crap for reproducing audio. It's good for making sounds pleasing to humans (except for the horrible scratching sound, of course). Ever wonder why the totaly voice-synth'd Britney Spears albums sell so many?. It's the same reason that people like vinyl records.
At 25 I just inherited my dad's vinyl collection and I've found they make music fun again. When digital distribution of started to catch on I stopped buying CDs, but then it felt like I was just buying filenames. Even when I occasionally bought a CD, I would just rip it to MP3 and put it on my shelf never to bother with it again. Convenient yes, fun not so much.
With vinyl all this convenience goes away. It's fun to go to the record store and sift through 1.00$ bins, or find pressings of newer groups. Then when you get home, you play it. You don't put it into your computer and hit button. You open it up, carefully take the disk out, notice the large liner notes, spin up the table and enjoy. It's more of an event than just rip. burn. play.
Sure it's analog, and there's the occasional distortion, but with a decent cartridge and stylus it's amazing how good new vinyl sounds. Finding spare sleeves to put your favorite albums in then putting the cover them on your wall make for some good excellent wall art too. To me it's similar to why I buy books even when I can get e-books. Life it's just about making everything streamlined and perfect, sometimes you need a little analog grit to keep it interesting.
Of course, I negated myself already by writing about ripping vinyl with 100% Free Software , but that's more for getting my dads old albums onto CD for him.
Are you quite serious?
Let's think about the actual downsides of DRM. Needing a special player? Turntables are not exactly readily available all over. Not being able to make copies? How do you intend to make copies of a vinyl album? Not being able to just drop songs on your MP3 player and go? Not going to be easy with vinyl.
If you want to produce a readily-transportable, widely compatible, copy-able file from a vinyl album (such as an MP3), you're going to need to record the output from playing it on a turntable, and then digitize that. Which you could do with any DRMed file. The old "analog hole".
I know this is /., but not every story that involves audio needs to whine about DRM.
Never mistake "can" for "should".
Absolutely right. As usual when someone posts something really smart that bucks the CW my mod points are taking a tropical vacation.
Sadly, CDs are not great either, for different reasons. Where vinyl introduces the uncontrollable variables you talk about (thermal variations, electrical noise affecting the very-low-voltage signal, never-ideal disc and needle quality, dust) CDs, because of their low sampling frequency (which should have been 96kHz from the start), mangle the waveforms at high frequencies. Still, CDs come a lot closer to delivering accurate reproduction in any form of real-world use. For starters, you just can't always keep dust away from your needle...
As for amps, it has always amazed me that people *love* the ones that introduce distortion and claim the accurate ones are "cold" and "technical." It's not the amp's job to be warm and emotional; it's the musician's. I run away from any component that advertises "warm" or "musical" sound; those are code words for distortion.
My own setup consists of various digital sources playing through a big Class D amp into speakers with poly cone woofer/midrange and planar tweeters. Everyone complains the sound is too cold. But it's dead-accurate with test signals and I can actually hear the detail in my recordings, not just "warmth" that may make me feel good but isn't there.
Have you seen and heard a DJ with vinyls? I mean, a real DJ, someone who mixes. I was peacefully sipping some malt liquor at a random electro industrial bar on a slow day. It was probably in the middle of the week; I recall that we were no more than five in the place. An electro industrial bar is not a place where you expect a skillful DJ. You expect a DJ knowledgable in the latest trends with a huge collection of obscure music that he had from download^W import from Germany or something like that. Songs go one after the other and there is some effort to keep that BPM constant and to make the transition beat-into-beat. I thought that this was the essence of mixing. Then, out of nowhere, came this rave DJ. He was actually a former electro industrial DJ who was visiting his former workplace. And he made a set.
I don't know how to describe the experience. He started a hard song on the CD player (Funker Vogt I think) then he attacked the turntable. He started with a Depeche Mode vinyls, and I hear you scream at the idea of eletro pop being mixed with Funker Vogt, but what he did was brilliant. He jumped on the EQ and isolated the good baseline so typical of Depeche Mode and gently blended it into the hard stuff, just the baseline. A moment later the vinyl was doing backflips over his head; he wanted to plug in voice sample that was on the other side. It was almost instantaneous, he waved his hand over the EQ, the voice sample played, the vinyl flipped again and we were back with the baseline. We assume that vinyls have poor seek time but, in the hand of an expert, a vinyl will seeks much faster than a CD. The DJ continued his dance, mixing in some elements of trance and goa, building an elecro industrial song out of other songs from a wide repertoire of electronic music. When he left, he was not the resident DJ after all, nothing was the same anymore.
I had discover that mixing was in fact a form of composition but it was all gone. I now pay attention to the work of the DJ. The DJ is an artist an his medium is extremely expressive. A good DJ will keep the dancefloor full but only a greet DJ will coerce people into dehydration and renal failure. When I see a DJ lifting the dusty cover of the turntable, I know that I'm in for a good show. I keep the ear open and I enjoy this rare skill that the CD almost killed.
yeah, because everyone can afford 10k for a turntable
Thanks to file sharing, I purchase more CDs
Thanks to the RIAA, I buy them used...
I own well over 1,000 pieces of vinyl, and many of them sound better than the CD. This isn't because vinyl sounds better, but because either the master was damaged or poorly remastered for CD. It is amazing how poorly mastered some CD's are. Digital recording does not compensate for an idiot behind the sound board, in fact it makes it much worse.
"To those who are overly cautious, everything is impossible. "
(It doesn't help that some DRM/watermarking techniques for digital sound degrades the quality further than the mere absolute rates would account for.)
Frankly, I don't expect this to be a major resurgence of vinyl/analogue formats, but if it forces even a few labels to beef up the stuff they're producing, I'm all for it. Who cares if vinyl "wins", if we all "win" by getting a better product? Of course, a better product really isn't likely, but the 0.01% hope that something could improve is better than the near-certainty of nothing changing if nothing challenges the status quo.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
I hate this stupid fad, and I say it as a vinyl lover an serious collector (I'm buying up over 10 records a week). These kids do this out of nonconformism, except that like most idiot wannabe nonformists, they don't know squat about anything (Disclaimer: I'm 20 years old, but I'm really an old fart in a kid's body).
They don't know how to maintain their records, they can't differentiate between high-quality records and a digital-to-analog dump (worthless). They buy modern or popular music that you can get on CDs without the disadvantage of noise floor, they don't have decent turntables, and worst of all, lack decent stylii (a bad stylus will damage the record). I buy records mostly for Jazz that's never been mastered on CD and other such rarities, and play it on a system that's worth more than $200 bucks; really, anything less than that is simply a waste.
And they raise the price and end up destroying the records and then you can't find anything decent because everything's scratched.
Why are people going to records? Because on the average, due in part to the technical requirements of the format, the importance of engineers, often times the quality of the music, and a few more decent reasons, vinyl is preferred. It isn't that vinyl is inherently better sounding- a good sounding cd can sound better than vinyl sometimes, but there are so so few that do this that it can't compare. Vinyl is better because back when it was put out they had professionals perform the mastering and whatnot. Vinyl has its limitations to be sure, digital in any format (16/44 or higher), but the vinyl almost always sounds better because they knew what they were doing with the music. The warmth factor is important because a LOT of the recordings and mixing done years ago were made with the explicit intention of the producing being played through multiple layers of tube and other such warming/coloring gear. That is why digital sometimes sounds so lifeless by comparison- it is through the digital recording of music being given the "breath of life" that it can sound like vinyl to a degree. For anyone interested, check out Steve Hoffman's forums (stevehoffman.tv) for more info. People who listen to vinyl aren't crazy- people who have never listened to vinyl and somehow have to dig at it because they don't understand the other details are. Good day :)
I once read a review of a McLaren F1 that included a phrase that stuck in my head ever since, even though it's turned up in countless sports car reviews over the years.
"Getting into and out of the cockpit of this beast requires the kind of agility that almost nobody capable of affording it possesses."
Likewise, by the time you're old enough to both care about audio and afford a decent stereo, your hearing will already have deteriorated to the point where you simply can't hear much of what you're obsessing over.
A young (i.e. under 20 years old) person with both excellent and absolutely undamaged hearing might be able to hear some output about 20KHz, but not much, and not loudly. (The falloff is quite steep.) The average teenager won't. A teenager who has been listening to his iPod/stereo for most of his life won't. Somebody in their twenties almost certainly won't, let alone thirties or forties.
Now, that's hearing above 20KHz. Hearing above 22Khz is an even taller order. This is one of the reasons why CD's were designed as they are. The engineers did their homework and decided that, even with moderately crappy filters that don't fall off nearly as fast as they could, a low-pass at 22.05KHz would be inaudible. I'm sure that with the wide range of human variability there are a small number of people gifted with exceptional hearing who are able to just barely hear output above 22KHz, and perhaps even a small number of these people will retain that ability past their teens. This, of course, is all when we're talking about test sine-waves. I wish any of these gifted listeners luck in picking out >22KHz details in a musical recording!
Statistics allow me to say with near absolute confidence that you, yes you, cannot hear the effect of the "brick wall" of CD's. Your dog might. Your paperboy is a remote possibility. You can't. I would happily slap down money on the table to bet that you could not tell the difference in a blind test between music that has been low-passed at 22KHz versus 40KHz. The effects of the "brick wall" are merely psychoacoustic.
As for the high-end audio market... What city do you live in? I live in a Canadian city of about a million people. (Calgary) This is not exactly LA, but we have at least half a dozen audio stores where you can sit down and listen to $30K+ systems. (Some that cost *much* more.) Everything from high end B&W to local-grown goodies like Totem acoustic. Yes, the audiophile market is not a high-volume one these days, but it never was. Also, the best sounding rigs I've heard have not been analogue. Some audiophiles really like the sound of vinyl playing through the grandiose euphonic distortion of a SET tube amp. My tastes tend towards something more... neutral. If I really wanted to add that much "color" to my music I'd feed it through an audio editor and apply some filters. I suggest you take a listen to a well recorded SACD or DVD-A album. (i.e. Not yet another #$@%ing remaster of a 30-year old Eagles album.) It's a shame neither format is doing very well because both formats can sound superb.
Anyways, whatever gets your rocks off, I wish you plenty of aural pleasure.
The purpose of copyright is to subsidize creation for the larger benefit of society.
The cost of copyright is that those good works which are created are not distributed to the population as widely as they might be.
The goal is to have an educated, enlightened society which has been exposed to a great deal of culture and knowledge, that they might be better peers and neighbours.
When 90% of the society is too dog tired from working in the fields to even think about doing something so frivolous as writing...
When only the few and the rich can afford recording gear and instruments...
When the cost to respect the copyright and maintain an artist is a pittance next to the massive costs of the manufacturing and distribution network...
In such a civilization, copyright is a defensible mechanism.
This is not such a world.
In this world, it is trivial to distribute information.
It is trivial to get your hands on the tools to create.
It is trivial to find the idle time to set your hand to it.
And with 6 billion of us and growing, if you don't want to do it without getting paid, go to hell. Someone else will do it, you're not special.
In this world, it is a trivial enterprise to make vast libraries of culture and knowledge accessible to peasants in the jungle.
Soon, it will be trivial to provide a copy of every creative work ever made to every man, woman and child on earth.
At which point, the only thing holding us back from doing so will be small-minded dickheads harping about their "rights".
If you're a creator, stop thinking about copyright.
Brainstorm for other ideas on how you might get subsidized by our society without it being necessary to keep people isolated from what you've created, and throw your weight behind getting them into place.
The writing is on the wall. Copyright is done. Find another way.
-1 Uncomfortable Truth
When you said near CD-quality, you weren't thinking of 8 track tapes were you?
Let's try the math again. First many digital radio stations use ABBAcast or something like it for near-CD quality at 33 to 40Kbs. Even if it's not CD quality it's certainly higher quality that anything that came off the vinyl in the first place. But let's ignore that and incorrectly assume we need 128kb/sec and see how the math comes out.
Audio modems don't actually use the full spectrum of the phone. last I looked they used about 3Khz. Now a vinyl record has a lot of bandwidth. the main limit on the bandwidth is the needles voltage/amplitude response falls off. That's why you equalize them. (which is why your stereo has a different input jack for phono than for tapes) You can only equalize then so far and get a decent sounding thing but you could push this much further if you went to a an analog coding scheme other than amplitude modulation. (hey that's what modems do! how about that).
So just to have some numbers lets make some up that are not completely crazy. Lets say we could push audio signal recovery out to 30Khz. So that gives us ten 3khz wide modem channels. And since the record is stereo that gives 20 total channels.
20*56kb/sec = 1060 kb/sec
1060kb/sec
Hey! that's what I claimed to begin with. I claimed I could fit about 8 cd quality channels (and here we mean 128Kb/sec) on a Vinyl record.
But wait! that's actually a gross underestimate. What determines the bits per second on a modem. it's a combination of two things, bandwidth and signal to noise. A vinyl record has enormously better signal to noise than a telephone. So the number of bits pers second my vinyl can support is vastly higher than the phone.
the shannon capacity scales as:
Bandwidth * log_2 (1 + SNR)
(where SNR is the singal to noise ratio in power)
to if I had 128 times better SNR on a record then that's about 8 times more bits per second.
So you see my Digital Vinyl smokes your CD.
Some drink at the fountain of knowledge. Others just gargle.
Depends on what CD you're talking about. The Loudness War has adversely affected CD quality for a decade now. The LP version of the latest Chili Peppers album doesn't have anywhere near the amount of clipping that the CD version has. It has a higher dynamic range.. this isn't "feels warmer" this is "measurably different wave forms".
It's not about making the sound EXACT, it's about making the sound BETTER.
CDs win for exact replication, but for things like club music, with lots of sharp synth sounds, bass, etc. A little "natural interference" from the actual physical motion of the vibrating stylus can make it sound "naturally artificial", or, quite to the effect such music attempts to achieve, surreal.
Plus, spinning vinyl is a HELL of a lot of fun. CD decks, not so much.
CAn'T CompreHend SARcaSm?
so, you could have all this technology in place and filters and so forth to take out the noise in order to get 8 128Kbps tracks... As each side of a record can hold ~25 minutes, that works out to 8*128kbps*25*60 bits of data per side... or about 192MB of data per side. That works to about 384MB that could be stored on a record... Even assuming you could fit 8x more data, that is still only 3GB of data on a record.
Lets compare this with a cd which is much much smaller than a record and can hold 700 MB per side (a two-sided one would hold ~1.4GB). Not quite up to the theoretical maximum that you claim your record could get, however consider the size, or the fact that a DVD, which is the same dimensions as the CD, and uses similar technology as it can hold up to 4.7GB on a single layer disc. This is far more data than the record can hold, and requires less sensitive electronics, and much less processing power to decode.
Looks like my "CD" beats your record after all.
...Volvo will offer a 6 vinyl album in-dash changer.
Jitter is actually a bigger problem than the filtering. Plus, 96 kHz... that means even higher clock frequency and more jitter sensitivity. It's a big issue, and the distortions produced when jitter (phase noise) gets in the DAC chip are complex and audible in the ppm, unlike the low order even harmonics of class A tube or MOSFET amps. A good technical paper on the nature of jitter-induced distortions in digital audio: http://www.essex.ac.uk/ese/research/audio_lab/malc olmspubdocs/C134%20Paper%20121st%20convention%20(c orrected).pdf
Class D amps have a long way to go. THD is meaningless, as the blind test studies by GedLee that were presented at the Audio Engineering Society convention a few years ago show, THD doesn't correlate with the distortion detectability, since the type of distortion is far more important. Crossover distortion from class B and AB stages, and effects of jitter, are audible in the parts per million. There's another type of distortion that doesn't affect THD measures at all, but is perceptually significant: thermal memory distortion. There's a good description of it and ways to decrease it here: http://peufeu.free.fr/audio/memory/ (there's also an AES paper linked there that describes how to measure it in real amps). Of course, tubes don't exhibit such distortion, and is my guess as to one of the reasons some people prefer them despite higher THD than typical solid state amps (however, this higher THD is simply due to most tube amps being simple; a tube with constant current load is more linear than any single solid state device; you can easily make a tube amp as linear as a solid state one if you use as many tubes as you would transistors).

In this world, it is a trivial enterprise to make vast libraries of culture and knowledge accessible to peasants in the jungle.
How? I mean, effectively. Will the peasants in the jungle even be interested in this panacea they're being offered? Or will it merely be someone thrusting "civilization" and "culture" upon them? Will they be interested in using computers to access this information, or will it merely homogenize them into the vast global monoculture?
It is trivial to find the idle time to set your hand to it.
Is it? Quality, anyone? Or have the great works of art that form the foundation of our history and culture been the work of hobbyists? Professional writers, musicians, painters, etc...have been around a long time, as much for the passion of their work as for the ability to pay their bills and put food on the table. In a world that is so quickly migrating to obtaining all this culture via a vast electronic network, how will these professionals (the one's who created the genuinely powerful, memorable, and quality material) be able to afford to continue to do so? Will the great works of tomorrow be the homogenized sound of Billy in his bedroom in his spare time, scarcely able to use the tools the develop such a work? When will he hone his skills? Has he heard of craft?
Where's the money gonna come from?
Brainstorm for other ideas on how you might get subsidized by our society without it being necessary to keep people isolated from what you've created, and throw your weight behind getting them into place.
You don't think artists try to do that all the time? Except for the large corporations and the elect few, art/music/writing/etc... is not all that lucrative a career choice unless you take advantage of every avenue you can possibly exploit to make money off of your work (and it is WORK.) Eliminating copyright makes it that much harder. Now, I'll be the first to admit that our copyright laws may have pushed the boundaries too far (I don't need a copyright that continues for an entire lifetime after I'm dead and gone, and frankly neither do my heirs), but eliminating copyright does not fix the problem.
This kind of mentality is part of what is killing the potential quality of art. Not the innovation part (for that I applaud you...artists should be innovative in all things, including how they do business), but the notion that anyone can do it, that it's easy, and soon everyone will do it and that's the end of that. Well, five minutes of fame on YouTube is fine, but that's it. It's no guarantee of establishing a place in culture except as a footnote. It's no guarantee of quality.
Soon, it will be trivial to provide a copy of every creative work ever made to every man, woman and child on earth.
At which point, the only thing holding us back from doing so will be small-minded dickheads harping about their "rights".
And then it occurs to me: this is all about the free lunch.
If you're a creator, stop thinking about copyright.
But if you're a consumer, get everything you can for as free as you can. If you're not willing to pay for quality, copy it. Spread it around. There was one copy that the artist made 65 cents off of. That's enough. That's all it's worth, because the copies are free.
Rights. Creators don't have rights. Only those looking for handouts do.
Do You Experiment?
First off, CD quality in 30-40k. Really? Then why the hell haven't we seen it anywhere? You don't think Apple would kill to have a more efficient format for storing and distributing music?
Well I can't find shit on anything called ABBAcast. To me it sounds like you confused ABBA, an old Swedish pop band, with Abacast, a radio streaming service. Of course, Abacast doesn't have their own codec, they use WMA, AAC, and MP3. Well 30-40k WMA is NOT CD quality, not even close, never mind MP3. The good codecs, like AAC and Vorbis do a decent job at 128k, it sounds as good as CD for most music on lower end gear (like portable players) but still not even close. You are talking in the range of 256k with most codecs to get something that is reliably as good as CD on good gear.
Also you seem to have no understanding of the problems of encoding to a broadband format.
For one, you can't stack your channels right on top of each other. You'll find that you have all kinds of problems. Look at any real broadband system, and you'll find out they've built in space between channels for just that reason. For example TV channels are specified at 6MHz each. Within that 6MHz is a video, colour, and audio carrier. Channel 2 is from 54-60MHz. However, the video carrier is at 55.25MHz, the colour at 58.83MHz and the audio at 59.75MHz. Channel 3 is then from 60-66MHz. You might notice that means there's nothing in the lower edge of the range and you'd be right. The reason is that you don't want the channels bleeding in to each other. You need to leave space if the system is to work.
Next, you've got the problem of assuming that two stereo channels can be used separately. Errr, no. In any analogue system, two adjacent channels will have some amount of crosstalk. That is to say a signal on one channel will bleed over to the other to some degree. You'll notice that most stereo amplifiers specify this amount. Well, with records, it's pretty high due to the way that the stereo signal is recorded. It's horizontal needle deflection, not two discrete tracks. Not a big deal for stereo audio, it's highly correlated anyhow and we don't need a ton of separation to hear stereo, however it'll fuck with your encoding real bad.
Then of course we get to things like error correction, assumptions that the SNR is equal with regards to frequency (it's not) and so on. I'm not going to go in to all the problems in detail since it ought to be apparent at this point that you didn't think this through.
"Somebody was trying to tell me that CDs are better than vinyl because they don't have any surface noise. I said, "Listen, mate, life has surface noise."
Stupid people think it's cool. Smart people thinks it's a joke; also cool.
Very funny! Why is it always that I see good stuff when I don't have mod points and there are days of drivel when I do?!
There is more to science than physics!

-1 point for reading comprehension. I said "near-cd" and I'm using the term that all the on-line radio simmulcasts use so go argue with them. my sole definition which I stated was "better than the original vinyl". Also you seem to have no understanding of the problems of encoding to a broadband format.
Thank you for your tedious flame sir. I won't bother to point you to my papers and patents on heterodyne modulation. For one, you can't stack your channels right on top of each other. You'll find that you have all kinds of problems. Look at any real broadband system, and you'll find out they've built in space between channels for just that reason. This is not even wrong. Let's see where to begin?. 1) first in theory there is no reason at all one cannot virtually stack channels without a buffer between them. run them through a acausal anti-alias notch filter. 2) They have to have that buffer for TV channels because the modulation schema and detection schema in use do bleed outside their channels. 3) this is all moot anyhow. The analysis was (*obviously*) just a gendanken argument about channel capacity. Once could do better not making artificial channel boundaries but just using the whole range directly. It's just that by thinking of it as channels of a modulation scheme one already knows the data rate for, one can quickly suss out the expected data rate for the bandwidth without doing any complex maths Next, you've got the problem of assuming that two stereo channels can be used separately. Errr, no. In any analogue system, two adjacent channels will have some amount of crosstalk. That is to say a signal on one channel will bleed over to the other to some degree...Not a big deal for stereo audio, it's highly correlated anyhow and we don't need a ton of separation to hear stereo, however it'll fuck with your encoding real bad.
BZZT. sorry no. all that is handled by the SNR term. cross talk sets a noise floor. What the noise floor is may depend on the modulation scheme. Now if you wanted to make a point here you should point out that that the plasticity of vinyl and needles may introduce non-linearities that can't support simultaneous use of the full audio spectrum. Granted. However that is only going to lower my argument by some fudge factor. And the argument is only an order of magnitude sketch to begin with so I that's not something to fret at this point. I'm not going to quibble over factors of 2, are you? Then of course we get to things like error correction, assumptions that the SNR is equal with regards to frequency (it's not) and so on. I'm not going to go in to all the problems in detail since it ought to be apparent at this point that you didn't think this through. Giggle. You are really taking this proposal seriously aren't you? The whole thing is a joke! if you really wanted to store more music on a cd just use Mp3s. good golly. However, the rather intriguing idea here is that if Mp3 had predated audio CDs Vinyl would have had a much larger storage capacity and signal to noise than we conventionally consider. It's very suprising how good vinyl really could have been.
Some drink at the fountain of knowledge. Others just gargle.
Digital apologists be damned, at the very top levels of achievement in sound reproduction, vinyl whips CD ass. At least it used to; CDs have gotten better and they are now quite good. (Some digital tape can be fantastic, beyond vinyl, btw.) In fact, CDs are now so good I would never suggest someone start collecting music on vinyl. But my 25,000+ LPs aren't going anywhere; they're too good to toss and too much work to change formats.
As for my few hundred pre-recorded reel-to-reel analog tapes - sonic nirvana.
Side note - I started my audiophile life as a digital fan. I was contemplating a career in music as a bassoonist and had lots of experience sitting with real instruments being played in real space by real artists. 8-tracks, LPs (on the crappy turntables I had access to), cassette tapes - they all sounded like garbage. I was used to the real thing and nothing provided it. So I didn't buy music at all. Then the CD came out and Phillips advertised it as "Perfect Sound Forever". All the magazines said it was the Second Coming. I swallowed the hype hook, line and sinker. I bought Vivaldi's Four Seasons on Telarc (a supposedly wonderful demo disc) and started shopping. The problem was, everything sounded like crap. Everything. I annoyed the guys at Pacific and any other place I could find and all the demos sounded awful. Finally, I heard about a "high-end" audio shop in Houston called Audio ProPhiles. I went in and the nice saleslady (it was a weekday afternoon and the place was deserted or else she wouldn't have spent any time at all with a poor college student like me) put my CD in the Phase Linear CD player (a Carver subsidiary, originally sourced from Kyocera, iirc) connected to the Krell electronics driving the original Martin Logan planar speakers. This setup, which cost more than a decent car, would surely show me the glory that was CD.
The sound came on and in less than two bars after the violins started I had shoved my fingers in my ears and was literally screaming at the saleslady to turn it off! Somebody had shoved a running dental drill into my ear canals; I was sure of it. I asked her what the hell was wrong with her demo system. She simply replied that "That's what digital sounds like." Then she sat me down at the Goldmund Reference turntable (supposedly the only one in the country at the time, having been bought off the show floor at CES), showed me how to use it, and let me spend an afternoon playing those beautiful, wonderful LPs. Lesson learned.
I've posted about this before and I won't go into details here. The short story is: Digital sucked in the beginning and continued to suck for many years. Then the players and production processes got better. Now, it's far more convenient than vinyl and, arguably, CDs sound about as good if a bit different. On the top end, it's possible to argue that vinyl is still better, but the top end requires more money than I'll ever have.
The bottom line is still the same as it's always been: If you want good sound at a reasonable price buy a subscription to your local symphony. Arguments beyond that I don't care to wage.
