Gracenote Media Database
Introduction This function is only available in audio CD
mode.
There is a version of
Gracenote® musicr
ecognition technology
on the COMAND hard drive. You will
recognize this by the logo which can be seen
in the bottom right-hand corner of certain
audio displays.
Many audio CDs contain CD text. COMAND
uses the information contained therein to
display the artist, album and trac kname.
If the audio CD does no tcontain any CD text
information, COMAND can use the
Gracenote ®
Media Database to identify
unknown audio tracks when in audio CD
mode. This is only possible if the relevant
information is saved in the Gracenote Media
Database and if the "Gracenote Media
Database" function is activated.
If this is the case, COMAND will display the
corresponding data such as artist, album and
track name in the relevant displays and lists.

Track and file names
When you create a disc with compressed
musi cfiles, you can assign names to the
tracks and folders.
COMAND uses these names accordingly for
the display. Folders that contain data other
than MP3 or WMA tracks are not displayed by
COMAND.
If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder .COMAND will then show
the name of the root directory as the folder
name.
You should observe the following when
assigning track names:
R track names must have at least one
character.
R track names must have the extension
"mp3" or "wma".
R there must be a dot between the track
name and the extension.
Example of a correct track name:
"Track1.mp3".

R
MPEG1 Audio Layer 3(MP3)
R Microsoft Windows Media Audio V8 and V9
(WMA) without copy protection
Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
R additional music files in AAC format with
the file extensions .aac, .mp4, .m4a
and .m4b, but not copy-protected iTunes
music files with the extension .m4p.
i If, in addition to MP3 files, there are other
music files in these audio formats stored on
the disc, the loading process may require a
longer time before the first track is played.
i The MP3 audio encoding method is under
license from Fraunhofer IIS (Institut
Integrierte Schaltungen – Institute for
Integrated Circuits) and Thomson. Permissible bit and sampling rates COMAND supports
MP3files of the following
