Audio mode
The unit may be unable to read individual tracks or the entire data medium
due to the data medium configuration or the devices and programs used for
recording. Information can be found on the Internet on the best ways to cre-
ate audio files and data media (compression rate, ID3 tag etc.).
Due to the larger quantity of data, it takes longer to read a data medium
containing compressed audio files (MP3, WMA etc.) than a normal audio
CD. Complex folder structures can also slow down the reading of a data me-
dium.
Playlists only determine a certain playing order. There are no files stored in
a playlist. The unit will not play a playlist if the files are not on the data me-
dium at the locations referred to by the playlist (relative file paths). Playing order for audio data CDs
Fig. 11 Example of an
MP3 CD structure.
Audio files  on data media are often organised by means of folders  and
playlists  to determine a certain playing order.
Tracks, folders and playlists on a data medium are sorted by name in alpha-
betic or numeric order. 
