    I have read that .aac files have preferentially better audio quality over compressed .mp3, and I agree.

    Converted audio files from youtube at, aac format. What struck me was that iTunes could not add the aac file - dragging the file into the library does not work, neither does importing via file>add to library.

    You guys can try it;
    convert to aac format via *or*

    I tried converting to mp3 format it works, but aac sounds better.
    Quicktime could play all no problem, but just couldn't get it into iTunes.

    I was wondering if the web converts to an old version aac format that iTunes is unable to recognise or simply apple trying to curb piracy (doesn't make sense that mp3 works then).

    Appreciate any advices please!
    Running MAC OSX 10.9.2, iTunes 11.1.5(5), *latest versions*

    I believe iTunes expects AAC files to be wrapped in an MP4 container(.m4a). You can take a look at this post about using ffmpeg to wrap the AAC file in a .m4a container without re-encoding the audio.

    Thanks you moviebiz!

    So the key to this problem is that iTunes does not recognise .acc files without the big A’s code tagged in it.

    Converting .acc to .m4a is able to solve it.
    MP4Box solution had only windows based GUI, I had used switch sound file converter and it worked well. :D
