    Apple Lossless on iTunes: compressed when downloaded to iPod?
    I've ripped many CDs to lossy AAC compressed files on iTunes. I'm going to hook up my Mac laptop to the amp in my stereo setup so I can start playing my playlists thru my floorstanding speakers.

    I want to re-rip my CDs as Apple Lossless files for better sound quality. I assumed I would need two libraries in iTunes, the AAC for downloading to an iPod (to save memory space) and a new lossless library for the better sound; but I was told that iTunes compresses Apple Lossless files when downloading to iPod so space is preserved on the iPod.

    Is this correct? If so, how much space does an Apple Lossless file take on an iPod compared to an AAC file (what percent memory comparing one to the other after downloading onto iPod)?

    I have my library in lossless from my CD's and when my wife's Shuffle is docked it automatically converts the selected music to Lossy without the need to do anything extra and my ancient iPod lets me decide between lossless or several different lossy formats.

    I do this. I have iTunes set up to rip in ALAC and stream it to my AV amp using Apple TV.I have iTunes set up to auto-sync in AAC to my iPhone like osxx.

    With regards to file size there are so many variables it's hard to give an exact figure. A typical AAC file is below 10Mb and some of my ALAC files are topping 40Mb.

    IIRC there is a checkbox in the syncing part of iTunes that offers to convert songs "on the fly" to the compressed format on the device only, saving you having to have and maintain two libraries. However, I'm wondering now if this only applies to the Shuffle or if it works for the Nano as well.

    It works for all models I believe. I have the option to convert to compressed audio for my iPod Classic.
