The CD Turns 25 Today

netbuzz writes "Seems like only yesterday to those of us of a certain age, but the CD turns 25 today. Philips, maker of the first CD on Aug. 17, 1982, estimates that more than 200 billion have been sold since. The younger set might have trouble appreciating the difference in auditory quality that the compact disc represented over vinyl or cassette tapes (some have probably never even seen a record). And all but true trivia buffs will have trouble coming up with the name of the artist on that first disc."

Marshall amps have been legendary partly because their brand of distortion is highly distinctive.

I think that initially CDs were intended to come in plastic cartridges that would protect the actual playing surface from scratches, but those were eliminated very early on. The CD as released is very fragile and prone to scratching. In the old days of cassette tapes, I could throw all my tapes in a big pile and still be fairly confident they would play (unless I left them out in the sun or something). If you try and throw your CDs into a big pile, you're going to get a big pile of scratched up coasters.

You can usually polish off scratches on the optical side, but any significant scratches on the label side will destroy the data. DVDs are much better in this sense, as the data layer is exactly in the middle of the disc.

      Another stupidity about the audio CD standard is that you've got this nice digital storage space, yet all the metadata is stored on liner notes only. Surely it wouldn't have hurt to add some kind of metadata into the spec, even if most early players hadn't been able to use it.

    Apparently (so the story goes), the discs were originally designed to hold 60 minutes of music. But the VP of Sony decided this was unacceptable, since it would not be long enough to allow uninterrupted playing of Beethoven's Ninth Symphony without a disc change -- the piece as usually performed is a little less than 1:15, or about 74 minutes.

    According to Wikipedia, there was probably more than just a love for classical music in here; the demand for 74 minutes as opposed to 60 (which necessitated 120mm discs instead of 115) was strategic. Polygram (one of Sony's major competitors) already had an experimental facility set up to make 115mm discs, Sony didn't, and therefore it was advantageous to force 120mm in order to start the playing field off level.

Had they produced the CD in 115mm format instead of 120mm, it would have been rather simple to facilitate a production deal that would put Sony at no disadvantage. And trust me, there's no way Sony would have gone in on the venture if they didn't have wording in the contract requiring something to that effect.

      Besides, I'm no engineer, but I don't think a retool from 115mm to 120mm for a brand new technology that had never been produced before was really that big of a deal for Polygram.

      Sadly for you your reasoning is completely flawed, because railways were not initially designed to carry people, they were made to carry coal, the fact is that standard gauge was set by George Stephenson, who set it so his rolling stock would be same size as rolling stock from horse drawn wagonways, which were the same size as normal wagons, which were set according to the size or a horse, and how much it can pull.

      In fact, if you design a railway specifically for people, you will find wider gauges to be better. The Great Western Railway was designed by Isambard Kingdom Brunel specifically for the comfort of his passengers, and used a massive 7 foot gauge, in order to make the ride smoother and faster. Russia and the British Raj both selected broad gauge railways because they has improved stability and were more practical design than standard gauge.

      Standard gauge is anachronistic, it only won out because of the prevalence of Stephenson's designs, if the worlds railways were built from scratch today, a much wider gauge would be probably be used. As a geek you ought to know that a lot of standards are set not by common sense, but because the big fish said so, Stephenson was the big fish, and he set railway gauges to the same size as road carts because it was cheaper to use wagonway rolling stock. So, the Shuttles SRB's are the size they aree because Stephenson was a cheapskate. Also, because he was successful, and because the north won the US civil war.

    Cue the vinyl fanatics who will whine about how "warm" their vinyls sound


    Actually, there's a bit of truth to that (and ditto on valve amps). Transistor amplifiers, and digital electronics also, suffer from a phenomenon known as "clipping" if you give them too large an input. (For an amp, that would be the at the amp's input, for digital, it would be during the conversion to digital process, if the input peaked over the ADC's max input, or during processing which causes the sample's value to overflow).

    If you take a decently powerful headphone amp (decently powerful - most headphone outputs on devices are very weedy), and plug its output into the line level input of another device, say, your soundcard, then playback the audio, it sounds like crap. Clipping is very harsh to the audio, and just sounds so bad. (People should do line-level checks as well - you can clip on those, but it's harder to come up with a decent demonstration).

    Or, take an MP3 or other audio file on your computer, and open them in Audacity or other audio editor. Simply apply the "Amplify" effect to 200%, then listen. A mess - you may be able to make out what's happening, but it sounds just plain bad. Unfortunately, a lot of MP3s are apparently created like this... people don't seem to know how to rip CDs, so do the D/A/D thing without properly setting levels.

    Valve amps, and vinyl don't clip when subjected to out-of-bounds input. Instead, they distort (which is why good guitar amps are valve based). This distortion makes the audio less accurate, but still much more pleasing to the ear. (And some argue that when it's distorted properly, even better). That's why valve amps are almost always in the power amplifier section (never preamp - the input levels to a preamp tends to be fairly standard (line-level, minding above)) - the preamp can easily overload the power amp inputs, which should trigger the distortion. If there are transistors in front of the tubes, they must be set so they don't clip before the tube distorts, or it's all for nought.

    (In vinyl, the distortion comes because the needle cannot move very far before it impacts the neighboring grooves).

    Alas, the vast majority of people don't actually configure their hardware correctly.

    No one has pointed this out, but early CDs actually sounded like shit. They were WAY under compressed so the noise of the signal path was very significant. Also, they were mostly encoded at the studio in 16 bit, so mulitiplies and stuff going on in the mastering process (most were mastered on analog equipment but there was a required digital transfer to the master). The early CDs I heard in the mid 80s were really trashy. Better than tapes, but not as good as records on a decent hi-fi. This was pretty much common knowledge amongst people who liked music. The real selling point, and what made me get on eventually, was the random track access. That was huge, and I believe that is really what made the CD take off.

    Interestingly, there was a kind of golden-era of CD sound in the late 90s when we had high dynamic range mastering equipment, before the loudness war pissed it all away in a hail of clipping.

    The most surprising thing I discovered during the mid-90s (before recordable CDs were ubiquitous) was how good metal tape with DBX or Dolby C could sound. The biggest revolution brought about by CDs wasn't at the home side, it was at the production side. Pre-CD, bass was arbitrarily rolled off to reduce the cost of making records and increase the capacity of a typical LP (low bass = wide grooves = reduced LP play time, loud bass = deep grooves = thicker records = increased manufacturing cost). It wasn't COMPLETELY universal (as rap/dance 12" singles showed), but for all intents and purposes, it was just the way mainstream records were mastered. As a result, mainstream home audio systems couldn't handle bass, either (remember the sudden appearance of subs and satellite systems almost overnight circa the mid-80s?) Because they couldn't handle bass, and to reduce mastering costs, cassette tapes had the same eq curve applied, and were bass-free as well.

    I still remember the favorite album of my childhood -- the Star Wars Christmas Album ("Christmas in the Stars", which, ironically, had Jon Bon Jovi (still a teenager) as its lead singer). At the time, I had no idea why it sounded so incredibly good with headphones on my Dad's stereo, but it did. Unlike the rest of my records, it almost felt like you could reach out and touch the music. It was a feeling I never experienced again until almost a decade later, when CDs were a few years old, and DDD mastering became the high-end norm. For Christmas in 1999, my parents bought me a copy of the newly-(re-)released "Christmas in the Stars" CD (my original record was destroyed by Hurricane Andrew... or more precisely, my parents' disinterest in trying to salvage what to them was just an old record that got wet and moldy along with everything else in the living room). Anyway, it was from reading the cover notes that I finally realized *why* the original album sounded so incredibly great: it was digitally-mastered almost a *decade* before most professionals had even *heard* of "digital mastering".

  22. Re:Happy B-Day by wirehead_rick · · Score: 4, Interesting

    Hmmmm. The real reason early CD's were dissed by audiophiles is because the CD's had the "harsh" sound. Original audio masters were mixed to make up for the extreme deficiencies of vinyl. When CD's came out these masters were transfered directly to the digital domain with no compensation at all. These early CD's sounded awful because all the enhancements for vinyl were not removed (not because of 16 bit transfers). This "harsh" sound of CD's was the largest complaint by audiophiles. No doubt because LP's have a long roll off of high frequencies (compensated for in the master) where this "harsh" sound comes from. LP audiophiles jumped all over this and some of the less intelligent ones today still hold LP's are better because of this early effect that has long ago been fixed.

    Once masters were re-mixed for true fideltiy there is no LP in the world that can compete with CD's. Even a 16 bit transfer of a master properly re-eq'd blows away the earlier vinyl based master.

  23. CD vs. vinyl audio quality by howlingfrog · · Score: 2, Interesting

    the difference in auditory quality that the compact disc represented over vinyl or cassette tapes

    There has been much argument about whether CDs or vinyl sound better. Here's some actual facts.

    • Vinyl stores more information than CDs do. Quite a bit more.
    • CDs are digital. When you convert from digital to analog or vice versa, you lose information. So any recording made on analog equipment (pretty much any recording more than 15 years old) then put on CD is hemorrhaging data when you put it on the disc and again when you listen to it.
    • Vinyl is analog. When you make an analog copy of an analog master, you lose information. So any recording made on analog equipment leaks data every time one piece of equipment transfers the recording to another piece of equipment. Instead of the two big wounds of a-d-a, there's a bunch of tiny ones with a-a-a-a-a-a-a.
    • When you start out with digital equipment, every time one digital device conveys the recording to another, the copy is literally perfect. Any and all degredation can be caught by checksums--and even if you don't do error-checking, a bit-flip or two will make far less difference in audio than other kinds of digital data. With digital recording equipment, a CD loses information only once--when you listen to it.
    • The quality of the equipment you play it on matters. Today's vinyl fanatics talk about how "warm" the sound is, but that's a feature of the player, not the media. There is no market for low-end record players today. Nearly every single record player manufactured and sold today is audiophile-quality. The best hi-fi systems with the best CD players and the best DACs (digital to analog converters) and the best speakers will sound just as much warmer than a $25 boom box from Walmart as an audiophile record player will. One of the biggest wins for any digital format over any analog format is that there's much less room for the player to screw things up. The cheapest CD players are easily ten times as good at conveying the information from the media to the amp as cheap record players were, when there were cheap record players. It's not even mathematically possible to make a digital audio player that sounds as bad as the record players that were mainstream in 1982. In fact, one of the reasons compressed audio has become such a big deal is that even the worst CD players provide better sound quality than low-end amps and speakers can reproduce.
    • CDs are not degraded by normal use. Vinyl records are.
    • With basic read-ahead for skip protection, CD players are more or less impervious to being shaken or bounced. Bouncing a record player will not only wreak havoc with playback, but probably even damage the media.

    Essentially, the vinyl fanatics are correct that a vinyl record will sound better under ideal circumstances than a CD. But making (and keeping) circumstances ideal takes time, effort, and money. In circumstances any more than marginally below ideal, a CD will sound better. Unless you're in the most extreme two or three percent of audiophiles, you're better off with CDs. That's why CDs won, and that's why they deserved to win. I'll keep my record player and my vinyl collection, and I'll tell you how much better vinyl can be than CDs, but CDs are indisputably the right choice for most usage.
