    Yes! This feature has been a long time coming and finally brings recording to the iPod, which has been lacking it compared to Nomad and Archos. Now I can record samples and concerts with something small and unobtrusive -- if expensive. I imagine the new iPod will find many interesting new uses with the docking port, such as loading into a car stereo. Anyways check out earth2willi.com for lots of free music downloads to install on your new iPod!

  3. New Input mode by slowtech · · Score: 4, Interesting

    I have been looking into using the iPod as a PDA (read only, of course), and I am really excited about this. With this feature you can either take audio notes on the run, or, if there is enough processor power for voice recognition, enter information into the Calendar / Address Book, etc.

    There is also a third option, which would be neat, to record the audio onto the iPod disk, and then have your Mac transcribe the audio when the iPod hooks up. This could be a work around if the iPod does not have the computing capacity for taking voice input.

    This would be so like Apple - they know we are all getting just a little sick of Graffitti and scribbling tiny marks on a tiny screen. Voice recognition / recording would make the iPod a PDA with a unique and convenient interface.

  4. Other New feature in the new iPods by gadwale · · Score: 4, Informative

    There seem to be new features in the iPods that weren't announced or well publicized. From my earlier post here:

    While reading Walter Mossberg in the Wall Street Journal I came upon this paragraph:

    "The standard cable still hooks into a FireWire, or 1394, a port many Macs have but few Windows PCs include. So, Apple offers an alternate cable for $19 that plugs into the USB 2.0 port that's standard equipment on new Windows PCs. It will also work, albeit much more slowly, with the older USB ports found on nearly every Windows PC in the past four years. This opens up many more Windows computers for working with the iPod."

    Went to the Apple website and sure enough - The new iPod dock can now connect to a USB 2.0 port on Windows machines . What is more - you can also use a USB 1.1 port for _really_ slow transfers!

    From Apple Website:
    "USB 2.0
    For PC users, the iPod will be able to sync files via USB 2.0*, which transfers data at up to 480 Mbps and comes standard on the latest Windows computers. USB 2.0 is also compatible with USB 1.1, although data transfer speeds are much slower."

    Looks like a smart move...

The kind of recognition you're talking about is a lot closer to understanding continuous speech, something which is a lot harder and requires a lot more processing to do well.

      As a non-iPod related side note, I've got this working with iTunes and my iMac (and its built-in mic). With the help of this Applescript and a Keyspan Digital Media Remote I can control iTunes by voice across the room, almost exactly as your example there is set up.

      But, to be honest, I don't know if a system similar to OS X's built-in voice recognition could be used with an iPod, at least conveniently. At least, with the Applescript linked above, on my 800MHz G4 it takes about three to five seconds to load the names of 128 artists to recognize. It would take significantly longer to do so on the iPod. (I guess the names could be held in RAM to make it quicker.)

      Probably only limited voice recognition with the hardware available.

      IIRC the iPod has an ARM processor in the 60-90 MIPS range. This could get you continuous speech recognition with a vocabulary of a few thousand words, but you'd probably need more RAM. Even if I'm wrong about the processor speed you'd probably still need more RAM.

      It wouldn't be hard to get a hundred word vocabulary discrete word recognition, to do perhaps:

      "iPod" pause "play" pause "metal" (or whatever)

      Disclaimer: I have programmed a limited vocabulary discrete word system and used a large vocabulary continuous speech recognition system.

Huge, heavy, slow transfer rates, shitty hardware, buggy software, had it replaced twice in three monthes, and then swapped it with an iPod) Guess what? It was useless: whenever you try to record from the internal microphone, the hard disk would start spinning (and put itself in motion every 2 or 3 minutes). The noise would cover any sound coming from the microphone. Though I got to admit that I had the best MP3 records of a spinning hard disk... they were just soooooo accurate. There would be similar problems on the iPod (even though the iPod hard disk only has to spin every one and then, because it has so much more RAM).

    The "record from line-in" feature was nifty, but I never really found an use for it...

    They'll have to buffer audio in the 32MB RAM, compress it, and when the RAM fills up, spin the HD and write it down. If they've got decent MP3(AAC?) encoding hardware on it, then they might not need to buffer the incoming audio at all, in which case I imagine they could avoid spinning the disk more often than once every twenty minutes or so.

    If they pull that off, you could get hours and hours and hours of recording time on a single charge. Er... but idunno about the power requirements of a decent mic. This might not be everything a bootlegger dreamed of, but close to it. They'll probably still need to carry around some kind of power source to drive their mic.

The WM8721 has line output capability, however, that wasn't implimented in Classic iPods. The new iPod (with dock connector) not only has line output, but as we've demonstrated it also has stereo line and mic input.

    >Er... but idunno about the power requirements of a decent mic.

    Well, I went back and looked in one of my manuals to see what the differences are, and mics can be powered with 3 volts (granted, this varies on model and make, but the theory is there), BUT, the voltage effects the mics output. Many "plugin power" sets on recorders (and in this case the ipod), send 3-4 volts which is sufficient.

    The catch comes with that mics operate best (and can capture the high end range from ~15khz upward) when they are powered with just under 10 volts. Granted, this is again an average, but most battery boxes that are used as either bass filters, or overload prevention supply the mics with just over 9 volts, and this enables the mics to have a greater dynamic range.

    Another thing is, most people who tape concerts (as thats what I gathered your example was) have battery boxes to prevent poor A>D transitions and other problems, and again, in my mind, it would be recomended to retain that battery box or A>D box as a precaution.
