About MPEG-4 AAC
Advanced Audio Coding (AAC) is at the core of the MPEG-4
AAC standard, which incorporates MPEG-2 AAC, forming the
basis of the MPEG-4 audio compression technology. The file
format and extension used depend on the application used to
encode the AAC file. This receiver plays back AAC files
encoded by iTunes ® bearing the extension ‘.m4a’. DRM-
protected files will not play, and files encoded with some
versions of iTunes ® may not play.

Note that DRM-protected files will not play, and files encoded
with some versions of Windows Media ® Player may not play.
