Permissible MP3 CDs In MP3 mode COMAND can read CD-R and
CD-RW CDs.Permissible file systemsThe permitted file system is

ISO9660/Joliet for CD-R and CD-RW.Multi session CDsWith multi session CDs, the content of the
first session determines how COMAND
treats the CD.
For example, if the first session contains
data in audio CD format and the second
session contains data in MP3 format,
COMAND will treat the CD as a conven
-
tional audio CD.File structureWhen creating a MP3 CD, you can organize
MP3 tracks into folders. A folder can also
contain additional folders.The root directory may have a maximum of
255 entries in total. (folders or tracks)

A CD may have a maximum of 255 folders
in total. A maximum of 255 tracks are per
-
missible per folder.Mathematically a maximum of 65025
tracks would result. However, this amount
is usually not reached since MP3 requires
approx. 1 MB storage per minute recorded.
Tips on caring for your MP3 CDsTips on creating MP3 CDs iCDs, software and hardware for writing
audio data to CDs are widely available.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD.
iProblems may be encountered during
playback of user-written CDs with a
storage capacity of more than 700 MB.
These CDs do not meet valid standards
as of this printing.

56 AudioMP3 operationTrack names and folder namesWhen creating an MP3 CD, you can assign
names to the MP3 tracks and folders.

COMAND uses these names in MP3 mode
for the corresponding display.Please note the following when assigning
folder and track names:
Per folder a maximum of 1800 charac
-
ters are available for title and folder
names combined.

Exceeding this number, COMAND can
-
not display all titles and folders.

Track and folder names must contain
at least 1 character.

Track names may contain up to fifty
characters. If a name exceeds this
character limit, COMAND will not be
able to display it in full.

Track names must have the extension
“mp3”.

A period must appear between the
track name and the file extension.Example of a correct track name:
Track1.mp3
Empty folders or folders containing data
other than MP3 tracks will not be dis
-
played by COMAND.If MP3 files are stored in the root directory
itself, the root directory also counts as a
folder. COMAND will then display the root
directory name as a folder name. Permissible MP3 formatsCOMAND supports the MPEG1
Audio
Layer
3 format.
Permissible bit and scan rates 
Fixed and variable bit rates up to 320
kbps

Scan rates from 24 kHz - 48 kHz
.
iCOMAND does not support ID3
tags.
Tips on creating MP3 tracks
iIn everyday speech, this format has
been replaced by the designation
“MP3”.iIt is recommended to use MP3 tracks
with a bit rate of128 kbps or higher and
with a scan rate of 44.1 kHz or higher.
Lower rates may impair quality. This is
particularly true if the sound function LOGIC7 Surround
has been activated.
