Inside the iPod, Past and Present

We mentioned the iPod Shuffle dissection a couple of days ago. Reader UtahSaint writes "Electronic Design have got a neat little article giving non-Apple employees an insight into the makings of the original iPod and the revisions made (on a technical level) with the 2nd and 3rd generation iPods. The third-generation iPod contains two power-management chips from Royal Philips Electronics, a TEA1211 and a PCF50605. The TEA1211 is a dc-dc converter that can switch automatically between step-down and step-up operation in response to changing input voltage. The PCF50605, a single-chip power-management unit (PMU), can adjust power-supply voltages to the lowest thresholds needed for functions in a particular power domain." And finally, sammykrupa writes "PC Mag has a great review of Apple's iPod Shuffle. It covers the quality of the audio output saying that it is has dead-flat frequency response, less harmonic distortion, and most notably, better bass response than its bigger siblings. The older iPods, especially the Mini, have been rightfully criticized for being somewhat deficient in bass, and although the bigger players have flat frequency response, they have trouble sustaining big bass notes."

  1. Makings of the original iPod? by Gob+Blesh+It · · Score: 5, Interesting

    The linked article is interesting from a technical standpoint, but it's also pretty dry--after the lead paragraph, the author doesn't really talk about the sweat and tears behind the scenes. Fortunately, the Times Magazine ran a story (reg-free link) a couple years ago about the human side of iPod, from conception to birth. Turns out the iPod didn't spring whole from the tip of Steve Jobs' magical wang. The article's worth a read if you're into this kind of thing.

  2. Sound Quality by exquisito · · Score: 5, Interesting

    The point is that the old Ipod headphone preamps didnt't have enough juice to power most headphones properly. What is the hardest frequency to reproduce? The bass. So, even with headphones and the eq turned up, the bass didn't sound as full and punchy as it should have. This was probably the worst flaw sound quality wise. The AAC or MP3 encoding at 128K are virtually indistinguishable from CDs for most listeners, but most listeners can hear the lack of bass. Its like something is missing.

  3. It kinda cements my desire to get an iPod Shuffle by hattig · · Score: 4, Interesting

    I don't need a massive capacity player, I just want to get my top 100/200 songs ever and carry them with me for those times I'm out.

    Not only is it diminuitive, great value (probably because of the lack of screen, but the 1GB Shuffle is £10 cheaper than a 512MB Sony, and £30 cheaper than a 1GB Creative in the UK). but it is actually pretty damn good.

    Will this be the first Apple hardware I ever buy? Where will it end?!

    It is 200 dollars cheaper. Probably the cheapest, yet useful apple product.

  5. Hidden iPod Shuffle features? by Anonymous Coward · · Score: 5, Interesting

    With all of the iPod Shuffle discussion and disections, I am surprised to see that no one has commented on the extra lines in the USB connector.

    If you look in the connector, there are five small lines between the main USB lines. (BTW, these are not included in the Shuffle's dock.) There is also NO USB logo's in any of the packaging or documentation.

    It looks like Apple may have some secret features up their sleeves.

  6. Re:Does it really matter? by Lisandro · · Score: 4, Interesting

    Well, that's you. 99% of the i don't want EQ on my music, of any kind, not even a bass cut from a poor output DAC. Classical, metal, rock, and electronic music are all heavy on bass, and it's stuff i listen to most of the time. I don't want poor bass reproduction just like i don't want poor highs or mids.

    By the way, if proper bass reproduction (not boombox-thumping bass like) makes you difficult to listen to the rest, your audio gear is poor. And not in the "it's not audiophile! get $1000 wires!" sense of poor.

    They obviously expect you to do some pretty strange stuff with it:

  8. Apple has done it... by Moustache+N+Tits · · Score: 3, Interesting

    I really have got to say, I love my iPod Shuffle. Although I played with the idea of selling it on eBay for a quick buck, the $10 was worth it to me to have something this chic. I never expected it that small or light, and it's so simple. I never looked at the screen of my iTunes, and in my car I put it on shuffle and never manually change the song. It works well for me but what's amazing is how popular the thing has been. Just like their big brothers they are getting scooped up left and right. You have to admire a company that can take a 4 year old player, put it in a nice case and have it back ordered for 4 weeks. Now if they would just release a product to compete with Microsoft's Media Center.

  9. "Sync with iTunes" is all the functionality I need by mrchaotica · · Score: 3, Interesting
    See, that's the thing -- I want a Shuffle because for me, it actually has more useful functionality than any other player. Here are my priorities in choosing a music player, in order of importance:
    1. Syncs with iTunes
    2. Cost
    3. Battery life
    4. Ogg (Vorbis and FLAC) support)
    5. Usability (easy access to "shuffle play" function)
    6. Expandable storage (SD or CF)
    7. Does NOT support Windows Media
    8. Extra features like voice recording, radio, etc.
    9. Low size/weight
    As you can see, only iPods satisfy priority 1, and the Shuffle satisfies priorities 2, 3, 5, 7 and 9 better than just about anything else as well. The only other player that comes close to competing, for me, is the Frontier Labs NexIA -- it uses CF cards and has zero internal storage, so it satisfies priorities ~2, 3, ~5, 6, 7(?), 8, and ~9 (the ~ means that it's okay, but not as good as the Shuffle). It's not quite good enough, though, since it doesn't sync with iTunes.

    Now, if the NexIA supported Ogg that would be enough to beat the Shuffle, but I've emailed the company about it and the strongest answer I've managed to get is "maybe eventually." Contrast this with the strong possibility that Tiger's iTunes will support it (which means the iPod should as well), and there's no longer any doubt -- the Shuffle is the clear winner.

    It's kind of sad, really, because I'd like to have removable storage, but being able to use the thing is more important.

  10. Mini + iTunes = Apple's HD TiVo by mveloso · · Score: 4, Interesting

    One thing Cringely forgot is that people love to download past episodes of TV shows and watch them again. I do that all the time with BitTorrent.

    I'm sure there'd be a subset of people willing to buy the current season of 24, Lost, Housewives, or American Idol and play it on their TV anytime - and burn it to disc.

    HD Movies? Who cares. Today's TV shows? Sure! At a dollar an episode, why the heck not? It comes out to be cheaper than the DVD. Fans'll buy the DVD anyway, because of the extras.

    Who knows whether this'll happen or not. But the box is just sitting there, waiting to be plugged into your TV.
