I n f o r ma t i o n P r o v i d e d b y :
Some versions of MP3, WMA, or
AAC format may not be supported. If
an unsupported file is found, the
audio unit displays UNSUPPORTED,
then skips to the next file.
In WMA or AAC format, DRM
(digital rights management) files
cannot be played. If the system finds
a DRM file, the audio unit displays
UNPLAYABLE FILE, and then skips
to the next file.
Combining a low sampling f requency
with a low bitrate may result in
extremely degraded sound quality.
