    Hi Friends,

    I am new to mac development and i have to develop one music processing related project.

    First i have to detect id3 tag of all type of songs like mp3, aac, wav.

    So is there any framework or class library is available for detecting id3 tag?.

    Best Regards.

    You are asking more questions than you think. There are a few versions of ID3, which are primarily used with mp3 files. The latest description is here:
    http://www.id3.org/id3v2.4.0-structure

    the tagging iTunes uses on AAC files is non-standard, but has been sort of reverse engineered. It is described here:

    WAV has no tagging, so don't worry about that.

    See this stack overflow thread for some links related to the use of QTKit for this:

    That may be your best bet.
