CD audio/DVD audio and MP3
Please note the following when assigning
track names:
Track names must contain at least one
character.
Track names must have the extension
“mp3”.
A period must appear between the
track name and the extension.
i COMAND does not support ID3 tags.
Permissible MP3 formats
COMAND supports the MPEG1 audio
layer 3 format.
i In everyday speech, this format has been re-
placed by the designation “MP3”.
Permissible bit and scan rates
Fixed and variable bit rates from
32 kbps to 320 kbps
Scan rates from 8 kHz to 48 kHz
i Only use MP3 tracks with a bit rate of 128
kbps or higher and with a scan rate of 44.1 kHz
or higher. Lower rates may result in impaired
sound quality. This is particularly true if the sur-
round sound function has been activated.
Notes on copyright
The music tracks that you can create for
playback in MP3 mode are generally copy-
right-protected under applicable interna-
tional and national laws.
In many countries,the reproduction of
copyrighted material is not permitted even
if only for personal use without the express
prior consent of the copyright holder.
Please check the current copyright laws
for your country and comply with them.
These restrictions do not apply, for exam-
ple, to your own compositions and record-
ings or for recordings for which
authorization has been obtained from the
copyright holder.
Notes about audio DVD discs
COMAND can playback commercially
available, prerecorded audio DVDs that
bear the following label. You will usually
find the label on the DVD booklet, the inlay
or the DVD itself.
i Audio DVDs differ from recordable DVD-R
and DVD-RW discs.
Data on audio DVDs are stored either in
uncompressed format or in lossless com-
pressed format. The sound quality on au-
dio DVDs is therefore better than on
recordable DVDs that contain MP3 data
because the MP3 format uses a lossy type
of compression. You cannot delete data
from or record additional data to commer-
cially available, prerecorded audio DVDs.
Please note the following information
about CDs/DVDs and pay special atten-
tion to the notes on copied and/or self-
written CDs/DVDs.
Other readable audio formats
COMAND can also read music files in the
WMA (Windows
® Media Audio), AAC (Ad-
vanced Audio Coding) and WAV (Waveform
Audio Format) formats.
i If other music files are stored in these audio
formats on a storage medium, in addition to MP3
files, the loading process may take longer before
the first track is played.
