It dumps the raw output of a QuickTime AAC stream to a file, which could bypass the digital rights management DRM algorithm called FairPlay used to encrypt music content of media files such as those distributed by the iTunes Store , Apple Inc. Apple s online music store . Although these resulting raw Advanced Audio Coding AAC files were unplayable by most media players at the time of release, they represented the first attempt at circumventing Apple s encryption. These early versions of QTFairUse would save only the raw AAC not contained in an MPEG 4 MP4 Container format digital container , but later incarnations properly supported full conversions. Released under the terms of the GNU General Public License , QTFairUse is free software . Technical approach Functionally, the purpose of QTFairUse is to convert protected audio files .m4p extension purchased from Apple s iTunes Store into M4a files, without DRM. To accomplish this task it uses a rather uncommon approach instead of removing the already present DRM, it waits for iTunes to play back the protected file and intercepts the unencrypted AAC data stream ... 15, 2008, the author has not updated QTFairUse for the latest version of iTunes, and the current revision is not compatible with that version.
