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 compres-
sion technology. The file format and extension used
depend on the application used to encode the AAC file.
This unit 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, or filenames may display incor-
rectly.

Microsoft Corporation. WMA content can be encoded
