An Overview Of Present, Future of Music Technology

prostoalex writes "IEEE Spectrum magazine is running a feature article on the state of music and current digital formats. They point to an interesting phenomenon in the digital music world that Steve Jobs emphasized as well: for the first time in music history, the next big format was not about better quality (SACD and such) but about better portability (MP3). 'It was only five years ago that the music industry was facing a civil war over the next-generation disc-based music format -- the successor to the wildly successful CD. At that time, hardly anybody doubted that the music would be encoded optically on a round plastic disc the size of a CD.'"

    All the future formats will be about replacing CDDA with "DRM".

    Oh, it will be marketed as being about increased audio-fidelity, but it's all about getting rid of those horrible "insecure" CDs.

    ...for the first time in music history, the next big format was not about better quality (SACD and such) but about better portability (MP3).

    Um... Wasn't that the point of cassette tapes? They were a dominant format for a while and the reason they replaced vinyl was their portability and robustness (maybe play-time, too.) Certainly it wasn't about sound quality.

    On another note, why does MP3 have to replace CD? For my money, I really don't think that there's any likelihood that'll happen. CDs are simple to use, store enough data, are lossless, and come with pretty packaging. All good things. I can't see why there can't be two parallel distribution systems.

      CD's are not lossless compared with vinyl, it's still a digital format whereas vinyl is basicically analog..

      I am not a sound engineer, but LP's were pretty noisy and had much less dynamic range than cd's. Different types of loss, but still a loss. Think of the sound you would hear as the needle rode in the groove before the music started. That sound was always there. There were many other quality issues with LP's, so I gladly switched to cd. It was a night and day difference in sound and convenience.

      I know there are LP zealots out there who love the warm rich tones of vinyl, but I for one welcome our cd overlords. LP's sucked.

      CD's are not lossless compared with vinyl

      OK, that's not what lossless means in this context. Technically every format is lossy compared to the original source because any recording is inferior to actually being next to whatever's making the original sound. Microphones aren't perfect. Headphones, speakers and even studio monitors aren't perfect. Let alone the recording formats.

      In this context, lossless means that when you transfer a clip of audio (or video for that matter) from one format to another, the two versions of that clip are completely identical. As far as I know, this is impossible with all analogue formats.

      If you copy a twelve track master tape of an album onto a record or a CD, it will lose some of its fidelity. If you copy a record to tape or a CD to tape, it will lose fidelity.

      This is the important part: transferring one digital copy of a file to another. Encoding a CD audio track or .wav or .aiff file to .mp3 or Ogg Vorbis is lossy, because cunning trickery is used to get rid of all the parts of the sound that most human beings can't hear. FLAC and Shorten, however, are lossless because they preserve the data exactly.

      For example, try this on a *nix machine:

      flac --best blah.wav
      flac -d blah.flac -o blah2.wav
      cmp blah.wav blah2.wav

      The first line encodes a wave file losslessly. The second line decodes it. The third line compares the two. They are identical.

      This is useful for several reasons. None of the reasons are how good it sounds; Ogg Vorbis quality three can probably convince most people (I know I can't tell the difference between that and the original audio). However, say you want to encode your CD collection to mp3, and then a year later you want to encode it to Ogg Vorbis instead. Transcoding (that is, transferring a file from one lossy format to another) sounds terrible. It's best to keep a lossless copy of your songs so that if you change your mind about the lossy format to listen to them in, you can automate the process.

      Another, less likely, advantage is this: you can use steganography to hide data in wave files (steghide does this, for example). Losslessly compressed wave files retain this hidden data. Now you can stash your porn or ROMs where no one will think of looking, and even keep a backup on a P2P client.

    Nahh... It's not really about forcing everyone to rent all the entertainment. It's about forcing CONTENT CREATORS to go through the traditional channels. Ie: Those pesky "indie" bands will be forced to go through a record company in order to sell music on cd, because all the cd players are made to block non-authorized content.

  4. MP3 vs the rest: Is file size really an issue? by Simon · · Score: 5, Insightful
    There seems to be an assumption by the technologists and music industry that people are dying for a better format to replace MP3. Better quality, smaller file sizes. I don't believe that is so.

    Filesize: But when a new computer comes with a 200Gb harddrive do most people these days even care that MP3 maybe isn't the most effective compression algorithm? I mean, you've got plenty for space so who cares if the typical music collection is 5Gb or 10Gb?

    Quality: Most people are happy with CD quality. 192Kb MP3 pretty much gives you that quality. Most people are more than happy with MP3, especially on a portable device where listen conditions are 'suboptimal' shall we say.

    Portablity vs DRM: This is the killer feature of digital music. The music industry wants to stop it, for everyone else it is all about being able to move music around. This is the one 'feature' that people do not want to see go.

    What I've trying to say here is that people are more than happy with MP3 and the 'problems' with MP3 really aren't an issue for the majority of people, while these replacement formats kill the one feature that people really care about.

    Good luck marketing your new formats, music industry. You'll need it!

    And this is a real shame, because technology is moving forward but the mediums are moving backwards.

    The two aren't mutually exclusive. Some people want portability, and that's fine, but what I want is a high quality update of the CD; with it's quality, maybe with more channels, and with the ability to scale it down *myself* if I want to take it with me on an iPod or such. Give me high quality, no DRM, and I'll work out what I want to do with, thanks very much. Oh, and I will pay for it, if it's DRM free, because that means it's portable to me (as well as being high quality). I have a rack of about 500 CDs sitting here beside me as a testament to that.

    And this isn't about digital files. Digital files could be great, if they were decent quality. I'd buy lossless versions of the digital masters by the truckload if I could... but not versions that are worse than the CDs I can already buy (128kbps typical online music store vs CDs 1411kbps).

    Anyway, I think the main reason that the MP3 is popular is not because it's just portable, but because of that portability it's easy to pirate. Listening to music on portable music devices is fine, but when you stick a 128kB MP3 on a decent hi-fi, or in a car, it sounds like crap. Until they provide us with something more compelling than free (but crap quality), they're going to have a big piracy problem (as opposed to a small one).

    But the record companies are going to learn one way or another. If what they put out costs the same, but in every other regard is a backwards step, there are going to be a lot of people throw up their hands in disgust and look for something better. Or at least different.

    I (we) don't just want portability, we want fidelity. MP3 and co do not provide that. They'll only get so far in the market without taking that into account.

    I think that you are right in that respect.

    128kbps MP3s have noticible artifacts when I play them back through my Nakamichi AV-8 amp + Mordaunt-Short speakers, that simply aren't noticible when played through an iPods headphones.
    Variable bit rate encoding helps a lot here.

    Makes me wonder why given all the hulabuloo about 'Digital is Forever' that Valenti and his morons trumpet, they persist in offering 128kbps DRMed audio from their download sites.

    I guess they simply want this distribution method to fail.

    Well said - I agree completely. I think it's very interesting to note that, despite the paranoia here on /. about DRM "slipping in the back door" because uneducated Joe Public will "just accept it", the evidence is that this just isn't happening. I don't think it's a coincidence that the market leader in "legal" music downloads (iTunes Music Store) is also the one with the least restrictive DRM. A lot of the pessimism is starting to be misplaced I think - "Joe Public" knows damn well that change is in the air for the music business (even if they can't put their finger on why - improved communications == easier copying == no need for specialist distributors of music) and they also figure that DRM is likely to stop them doing what they want with their music. And sensibly, they aren't buying the devices that the consumer electronics companies (under pressure from the RIAA) want to sell them - devices crippled with DRM that let you do LESS with the music you've bought! I also don't think it's a coincidence that the market leader in portable music devices (the iPod) is one that primarily supports a completely unencumbered music format (MP3). Despite the hype about being the "Walkman for the 21st century" the offerings from Sony that insist on burdensome conversion to ATRAC, and harsh DRM, are nowhere - for this exact reason.

    I also find it instructive, whenever a music industry lapdog or article starts lauding "copy protection" (as this article does) to mentally substitute the phrase "business model protection" because that's what it's all about (protecting rights to exclusive distribution of music). But there's no doubt in my mind that consumers have rumbled this and won't let the market players get away with it.

    How about this for a theory - that for most non-Hi-Fi types (IE about 90% of the population), they just don't have the gear to get any benefit from SACD (like the amps/speakers).

    For many people, music has become more like a "soundtrack" to their lives. Things like personal stereos, computer CD players and car cassette/cd increased the market for music because people would not have to sit down to listen, but could have it around them. However, the equipment for most people generally has low quality amplification.

    In all these, cases though, portability of the musical content will be vital. I don't want to buy a CD for my audio system, another format for my car use, and another for my PC.

  9. Re:SACD vs MP3 by Anonymous Coward · · Score: 3, Insightful

    Well it is a pity to see you using this "piracy" language. Nobody owns music and nobody should make another person feel bad for wanting to listen to music. It's a real shame you would pin a criminal label on people for listening to music. I supposed reading a book in a library is a form of asault?
    If commercial artists don't get millions of dollars for cranking out commercial crap, that's a real heartbreaker. If I want to listen to their crap for free, well good for me. This is the liberating nature of technology. The supermarketed stars had their day. Now it's time for the people who aren't into music for the money to have a turn. If the superstars want to play, then good for them. This isn't exclusionary, this is embracing music for everyone rich and poor and that's the right thing and a good thing and you have no reason to call people names over it.
    But I would agree that portablitity would most likely only be a priority to Steve Jobs since he's so heavily invested in his portable player.
