Audio Recording on New iPods

Vertig0gitreV writes "Over at iPodding they are reporting that in the Diagnostic Mode of the new new iPods (released on the 28th of May) there are two options for audio recording: mono through the headphone jack, and a stereo line-in through the docking port via the yet-to-be-announced line-in adaptor."

  1. in a word: Finally! by Anonymous Coward · · Score: 5, Informative

    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! It's registration and advertisement free, untouched by the RIAA, available in various genre and fileformats, and uncrippled by DRM.

  2. 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...

    Didn't they use exactly the same procedure when they introduced the remote? At least for my 5 Gig iPod they did. :)

    Very high end mics (floor mics for stage productions, etc) use a 48 volt power source. Regular everyday microphones generate a small voltage by being moved by the sound wave that is being recording.

    There is a lot of decent dynamic microphones (self-powered microphones) on the marked. But these work best with song/speech. If you want to record enviromental sound you would need a condenser mic, which needs 48v phantom power. AKG has a lot of good dynamic and condenser microphones

  6. Mic voltage [Re:Wonder how they avoid spinning.] by saitoh · · Score: 2, Informative

    >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.

    Actually, according to ipodding.com in this article, the classic iPod cannot encode in analog.

    Classic (Scroll/TouchWheel) iPods use the Wolfson Microelectronics WM8721 DAC (digital to analog converter) and can not encode analog (audio) input into digital (MP3, ACC, etc....) 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.

  8. Phantom power, bias voltage & passive micropho by mah! · · Score: 2, Informative
    To make it very short:
    1. Professional (studio) microphones usually need phantom power (11 - 48 volts) on a balanced type connector (XLR for example), usually monophonic.
    2. Bias voltage (1.5 - 9V) is used with small, portable microphones like the ones people connect to portable minidisc recorders or professional tape recorders. All portable devices of that kind I've used have it on the mic input port - unbalanced stereo 3.5mm connector type.
    3. Professional (stage) microphones are either passive (like the omnipresent SM58) or active - in which case they likely have built-int batteries.
    If Apple allows a microphone to be connected to the iPod, it'll likely be of the 2nd type.
    More info at Shure for example.
