      First of all, beat matching is not that hard. A couple weeks of practice and any body can nail it, whether it's variable speed turntables or digital sources with knobs for simulating the same thing.

      Secondly, if you don't know how to mix songs together by theme, you simply don't know your music. Go home and listen to your entire library a few times and come back when you're ready. Sheesh!

      Finally, nobody ever gives a fuck about synching the beat mix except for other DJ's. A bad transition will not clear the floor... I have, in the past, deliberately done ultra-shitty, gear-grinding shifts between tempos, just to see for myself. A good DJ doesn't need to keep things at a steady 112 BPM. At all. He just needs to know how to read the crowd. Sometimes slowing speeding up or slowing down a track by about 4 BPM can really ruin the feel of the song anyway. How you work the room is way more important than how you work the wheels, even if mastering the turntable does make you feel like some kind of rave god.

      DJ'ing is not a difficult task, if you know how to deal with people. Come to think of it, the human element might be why so many geeks think it's hard to do. Hmm....

    No, you can't scratch with the old CDJ-500's, but the style of music I spin (mostly house and techno) doesn't necessitate scratching to get a good enough sound for people to have a good time and even cheer! :-) Also, I've found that people are more often intrigued by the use of pro CD players and want to find out how they work, rather than being put off by them because they "aren't vinyl".

    Club DJing is NOT all about scratching, it's about providing a great set of tunes, mixed well and mixed appropriately, that your audience that evening will enjoy... no matter what method you use to get that.

    Now turntablism -- that is about scratching :-)

    Speaking of turntables and scratching, there are products out there that do a fine job of bridging the gap between traditional vinyl and the "digital DJ" world.

    One is Pioneer's CDJ-1000, which allows you to scratch audio CDs with its touch sensitive jog dial. I've had the chance to play around with these, and they're awesome!! While there is obviously SOME sort of latency, it's definitely not noticeable by humans, and approaches zero :-)

    Also, Pioneer now has a professional CD player that can play MP3 CDs. I'm sure before too long they will merge the two together into a unit that will play MP3 CDs and let you scratch them intuitively like the 1000.

    Perhaps the best example yet is Final Scratch. Some well-known DJs use this, including some that've used it back when it ran on BeOS. Now it runs on Linux though! :-)

    It consists of specially-encoded vinyl that you play on standard turntables, which are hooked up to a controller, which is in turn hooked up to your laptop which is presumably filled with MP3 and WAV files.

    Essentially, you are able to play MP3 files WITH VINYL. I believe there is a slightly more perceptible latency than the CDJ-1000 but not so much that it's frustrating to work with.

    What Parrish is describing (slecting a playlist) is, as mentioned in the article, something any moron can do. The only problem is the fact that this isn't DJing. Picking a playlist is only the start of what a good DJ does. The DJ then has to mix them together in a way that sounds natural and unforced, that takes more than just matching the beats up, it's also good to make sure that the sections are matched (sections being the 32 or 64 beat repetitions in music). If they really know what they are doing then they can start to think about key mixing (ie. keeping the songs you are mixing together in the same key), a difficult trick when altering the speed of the record will put into a different key.

    Then there is the fact that REAL DJs can have at least two tracks going at the same time, without making it sound awful. They don't just use this to mix from one track to another. They can also use this to add an element of one track into another, without leaving the original track.

    DJs can also use their mixer to make a track sound very different to what's on the vinyl. Using EQs the DJ can emphasize or reduce the Bass Midrange and Treble, effectively cutting instruments out or bringing them to the fore. Some mixers like the Pioneer DJM-600 allow the DJ to also add effects like Echo, Flange, or Reverb. It's even got a mini-sampler built in, allowing the DJ to grab a section of a track and create something new with it. Well, partially new anyhow.

    In short, if you don't think there's any artistry or talent required to be a DJ, then you simply don't understand what it is that DJs can do. I haven't even begun to cover the fact that a DJ is also required to understand, respond to, and influence the vibe of an evening.

Combine all of this introduced noise with a dancefloor full of people and what you're hearing isn't even close to the original recording.

      This is why I said enough with the mysticism. If you're on a dancefloor and you reckon you can hear "crisp highs" and "warm basslines" then I'm calling you deluded. It doesn't matter how damn good the data source is: there are dozens of systems between the data source and your ears and none of them are perfect.

      It's not mysticism, just an understanding that people are really good at detecting subtle differences in quality, even if it's not at a conscious level.

The best way to prove this is to get you go to a place that sells sound systems that can handle Super Audio CDs [superaudio-cd.com]. When I did this they played me two recordings of a guitar concert, one regular CD (44.1kHz, 16-bit), the other a SACD (~2.8MHz, 1-bit). None of the other settings were changed. The difference is startling.


      That's because the two are mixed differently so you should hear a difference. (Yup. different mixes same disc.)

      The oly real reason that SACD exist is that sony wanted to grab a slice of the audio on DVD market. An to really make som cash you need to control the standards. Unfortunately for sony the reasonable way to do things were allready well known (store PCM), and they needed somthing novel to patent.

      Thus were born DSD encoding (as is used on on SACD). The fact of the matter is that DSD encodes far less information than a similar bitrate PCM stream (SACD is comparable with CDDA in fidelity) as most of the signal energy is spent in storing noise. (Take a look at the output of a delta sigma noise shaping modulator and you will see what I mean).

      You can of cource not actually hear this as CDDA allready goes well beyond what is humanly perceptible. Though as SACD mandates a single bit encoding it may be possible to create pathological signals which will sound markedly worse in SACD that what might be possible on CDDA.

    ObAbstract - i've been DJing for over 10 years, headlining festivals with up to thousands of people, and been a long time fan and admirer of really good DJs. I learned on vinyl, but have been encompassing more advanced media in recent years.

    The move onto solid state media is a good, and inevitable one. The demands on a DJ are higher than ever before, and more tools are needed for the job. Some tricks *need* preparation to be performed, if for instance you want to cut out a middle chunk of a song, or want to overlay a track with a large number of samples very close together - these simply aren't possible on a traditional dual-turntable setup.

    Some very big DJs have access to vinyl-pressing facilities, so can play around with tracks and then have them available to play from a 12" - but hardly anyone can afford that. So there have to be other solutions.

    There will always be people arguing that one approach is better than the other, that one needs more skill than the other. This is ridiculous - both approaches can take time and skill, to become adept enough to create a good set with the tools you have. Vinyl is (for now at least) the most tactile "interface" for playing with music, though many other dj-quality units (such as CD players) compensate for their lack of interactivity with some neat tools, such as automatic BPM counters, instant dropping, better pitch or indeed fixed-pitch tempo controls, and frame by frame shifting. These already show some benefits over vinyl in some situations. Harddrive or solid-state solutions provide further benefits, such as instant accessibility, visual wave representations (it's really nice to be given an on-screen reminder that the track goes into a break in 15 seconds time), and so forth.

    The real benefit is that both approaches have their strong points, as well as limitations, so people benefit from even more variation, tricks and fun stuff in their sets. The best solution would be to have all the equipment available, but this would require all the skills across the board to use properly.

    If you're interested, I've been using a laptop/mp3 player live to augment DJ sets for years now. I ususally use the mp3 player for sample queuing, the laptop for processing or playing preprocessed tracks, or queueing large numbers of samples - you want to get 15 samples right in a minute, it'll be VERY tough with a regular mp3 player. And impossible on vinyl. Add these to 2 CD players (sometimes more) and sometimes a turntable, and you have what I usually use.

    I have some sets available for download, that hopefully can withstand a slashdotting ;) And if you're into vinyl-based DJs can show you the different sorts of tricks that can be achieved with these mediums.

  40. You mean *not nearly enough* storage room for a DJ by DJ+Wipeout · · Score: 2, Interesting
    An ipod has -way- too much storage room for a DJ.

    You're wrong there. A friend and I did a club-style radio show for 8 years, mixing with Denon CD Players and vinyl. We brought approximately 250 CDs every week, which at roughly 50MB/CD once converted, which comes out to 12.5GB. However, our complete collection of DJable music is much closer to 1500 CDs, which comes out to 75GB. I think it'll be a while yet before you can fit that in two off-the-shelf, unmodified ipods, much less one.

    You'll also notice I've made no mention of the 18 crates of records we own which have not been ripped yet.

  41. This article was not interesting at all... by steppin_razor_LA · · Score: 3, Informative
    I hate to be a troll, but I'm a little bummed this article made it to slashdot. I read it last night on Yahoo and was only impressed with it's lack of newsworthyness.

    The recent Slashdot article on Digital DJ Turntable was far more interesting.

    Lets recap this article. Some people have figured out that you can put a bunch of music on a computer or ipod and play that at events. Wow! You say this technology allows you to put together a list of songs and then play then in a row one after another???

    Look at who they interviewed:

    But Kirkendoll, who calls himself "The Podiatrist," was hired for his collection of music and penchant for feeling the vibe of a crowd, not his ability to mix or scratch.

    In other words, this is the guy who plays music at your wedding.

    What the story should be about is about some of the developments in technology that allow *real DJs* to perform instead of vinyl. When I say *real DJs", I mean those that perform at clubs that use beatchmatching, effects, and other techniques to create a fluid music listening experience.

    AtomixMP3 has been making some good progress at allowing people to use MP3s like turntables. Unfortunately, it still doesn't have anything that allows DJs to be able to "see" the CD the same way real DJs can apparently visually check out the grooves on the record.

  42. that makes it even worse by Trepidity · · Score: 2

    FM radio and MP3 encoding both degrade audio quality, but do it in different ways. So if you play an MP3 over FM radio, you don't get the worse of the two qualities (which would be normal FM radio quality, as you seem to assume), but you get in effect quality that's degraded by the sum of each separate degradation. So it sounds terrible.

    As a simple example you can try at home, take a CD and encode it to a 128 kbps mp3. Then decode that mp3 back to WAV, and encode it to a 128 kbps mp3 again, using a different codec. Your re-encoded 128 kbps mp3 will sound terrible compared even to the original 128 kbps mp3.

    Perhaps soon the legal issues will weigh over the artistic issues. The RIAA is working to make every public performance illegal and then decide whether to prosecute according to how much money you feed back to them after the commission of your 'crime'.
    In these situations, it's a lot easier to run away from the police with 4000 songs in storage medium the size of a video cassette than to try and make a quick exit carrying two turntables and 4000 albums.

  45. What on Earth are you talking about? by kikta · · Score: 3, Interesting

    The topic is about DJ'ing with MP3's. Now, I can see arguments about the lack of scratching (still something of a problem), beatmatching (programs do exist & and are pretty damn good, IMHO), and possibly computer problems "crashing" the party, so to speak. What I can't understand is all this bullshit about lack of sound quality! This is the same bullshit all the analog-obsessed DJ's of the world started spouting when the rest of us started using CD's in our performances. Who the hell cares about the "warmth" of the sound??? I still remember when I started using MP3's to DJ and I never had comments about them. Starting with parties I did back in 1997 while I was the house DJ at the Delta Upsilon house at Carnegie Mellon, I would switch between vinyl, CD, CD-R's with converted MP3's on them, and MP3's played off my laptop. Guess what? It wasn't a bunch of old people sitting around bitching about the lack of "warmth" in the sound. It was a shitload of college kids getting piss-drunk and having fun, in part because of me. They didn't complain about the sound quality at the beginning of the parties when sober & they didn't say a word at the end when they were drunk & tone-deaf. I would mix & beatmatch with simple utilities (whose names escape me) downloaded off the net. For scratches, I would impose the turntable's sound with the mixer. The trick was finding something appropraite to scratch with a paticular song, however this made me a much stronger DJ, not the other way around. And as far as the image goes, the bitches loved coming up there and seeing a laptop running Winamp mixing in with the CD's. They thought it was the coolest shit they'd ever seen.

    So, to conclude, not only does your argument (sound quality) have nothing to do with parties, but all of the other arguments against MP3 DJ'ing are either bullshit or pretty weak as well.

    "has more sonic range than CDs"

    Sonic range? What?
    Dynamic range: no...
    Frequency range: no... ... So, what is it?

  48. Re:Why do we really need DJ's? by Golias · · Score: 2
    I love vinyl... but if by "sonic range" you mean dynamic range, you are wrong. CD's have a lower noise floor. Not that it matters, because pop music is almost always extremely compressed (I don't mean the data, folks, I'm talking about sound compression here), and most PA systems sound like crap.

    Oh, if you meant frequency response, you would also be wrong. CD's reproduce the extreme lows much better.

    The main thing that vinyl has going for it is the fact that a 44.1 sampling rate means that a signal at 11 KHz (which is high, but well in the range of human hearing) has only 4 samples representing the entire wave, so the timbre of high-pitched instruments (like trumpets and violins) can sometimes be a little off on CD's. There are a lot of overtones above the range of human hearing that we can notice the absence of if it's part of a note that we can hear. However, on a PA system in a noisy dance club, nobody will notice that difference. Our brains tend to fill in the lost sound we expect to hear remarkably well.

    By the way, the "warmer" sound of vinyl is really due to equalization error. The bass on all records is tweaked way down to make cutting the grooves more practical, and a little equalizing pre-amp in your turntable pumps it back up. (That's why amplifiers have separate inputs just for phonographs.) This process tends to add a little mushiness to the bass and low mids. The vinyl "warmths" is actually a distortion of the source material. A pleasant distortion, yes... but fans of turntables began to admit this to themselves over a decade ago. It's warmer than CD because it's warmer than the source track. Digital actually got kind of a bad rap in the early days because of it... a lot of studio methods and a lot of "high end" equipment that people considered ideal were built around making records sound more realistic, which meant compensating for the quirks of vinyl sound. When playing CD's of albums recorded for vinyl, on systems tweaked for vinyl, a lot of audio critics found CD's to sound "too bright". It wasn't the fault of the media, it was just that the problems all that stuff was compensating for no longer existed, resulting in a sound that was bad in the other direction.
