    Specs:
    27" iMac - Intel Core 2 Duo - 3.06 MHz - 4GB RAM - 1TB HD - ATI Radeon 4850 512MB video
    iTunes v. QuickTime
    I searched for this; my apologies if it's been discussed -- just point me to where. If not....

    Has anybody noticed a difference in audio quality between QuickTime and iTunes? It seems to me there's a difference and to my ear QuickTime sounds better. If true, why would that be?

    I have heard people say that iTunes has an built compressor, or something to that effect, that cannot be adjusted or removed, its just part of the iTunes program, so maybe that is it?

    iTunes uses QuickTime for playback, so the reproduction quality is the same. However, iTunes has an equalizer and other adjustments, and QuickTime is just a straight player.

    If you made all your MP3's use the ACC codec i reckon that it would sound as good as your Quicktime experience ...
    That...makes...no...sense...whatsoever! My eyes cross just looking at it. MP3 and AAC are totally different formats. MP3 is part of the MPEG-2 standard, and AAC as you note is part of the MPEG-4 standard. You can't have an MP3 that uses the AAC codec.

    I'm new to iTunes and OS X .... I've been looking for an adjustable equalizer....where do I find it? I haven't found any adjustable audio qualities for either QuickTime or iTunes. Maybe that's why there's a difference on my machine.
