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 which 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 must observe the following when assign-
ing track names:
track names must have at least 1 charac-
R
ter.
track names must have the extension
R
"mp3" or "wma".
there must be a full stop between the track
R
name and the extension.
Example of a correct track name:
"Track1.mp3".
Permissible formats
COMAND supports the following formats:
MPEG1 Audio Layer 3 (MP3)
R
Microsoft Windows Media Audio V8 and V9
R
(WMA) without copy protection
additional music files in AAC format with
R
the file extensions .aac, .mp4, .m4a
and .m4b, but not copy-protected iTunes
music files with the extension .m4p.
i If, as well as MP3 files, there are other
music files in these audio formats stored on
the disc, loading may require longer before
the first track is played.
i The MP3 audio encoding method is under
licence from Fraunhofer IIS (Institut Integ-
rierte Schaltungen – Institute for Integrated
Circuits) and Thomson.
Permissible bit and sampling rates

types:
constant and variable bit rates from
R
32 kbit/s to 320 kbit/s
sampling rates of 8 kHz to 48 kHz

Only use tracks with a bit rate of at least

able deterioration in quality. This is espe-
cially the case if you have activated a sur-
round sound function.
