Media Database
Introduction This function is only available in audio CD
mode.
There is a version of
Gracenote® music recognition technology
on the COMAND hard drive. You will recog-
nize this by the logo which can be seen in the
bottom right-hand corner of certain audio dis-plays.
Many audio CDs contain CD text. COMAND
uses the information contained therein to dis-
play the artist, album and track name.
If the audio CD does not contain any CD text
information, COMAND can use the Grace-
note ®
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. 200

Normal Track Sequence The tracks are played in the normal order
(e.g. track 1, 2, 3, etc.).
In MP3 mode, the track order is determined
by the order in which the tracks are written to the MP3 data carrier when it is created.
Alphabetical order is the most common.
Once all the tracks in a folder have been
played, the tracks in the next folder are
played.
R Random Medium Random Medium

Audio CD and MP3 modeAudio

Multisession CDs
For multisession CDs, the content of the first
session determines how COMAND will proc-
ess the CD. COMAND plays only one session
and gives priority to the audio CD session.
If possible, use COMAND to play only CDs
that have been written in one session.
File structure of a data carrier When you create a disc with compressed
music files, the tracks can be organized in
folders. A folder may also contain subfolders. The disc may contain no more than eight
directory levels. Files beyond the eighth level will not be recognized by the system.
i COMAND loads up to 15,000 tracks from
an SD memory card or USB storage
medium.
Track and file names When you create a disc with compressed
music files, 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 char-
acter.
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". Permissible formats COMAND supports the following formats:
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 Integ-
rierte Schaltungen – Institute for Integrated Circuits) and Thomson.
Permissible bit and sampling rates COMAND supports
MP3files of the following
types:
R fixed and variable bit rates from 32 kbit/s
to 320 kbit/s
R sampling rates of 8 kHz to 48 kHz
COMAND supports WMAfiles of the follow-
ing types:
R fixed bit rates from 5 kbit/s to 384 kbit/s
R sampling rates of 8 kHz to 48 kHz
COMAND does notsupport WMAfiles of the
following types:
R DRM (Digital Rights Management) encryp-
ted files
R variable bit rate
R WMA Pro
R 5.1 surround sound
i Only use tracks with a bit rate of at least
128 kbit/s and a sampling rate of at least
44.1 kHz. Lower rates can cause a notice-
