USB MP3/WMA Overview
Note on MP3
•
MP3 is short for MPEG Audio Layer 3 and
refers to an audio compression technology
standard.
•
This product allows playback of MP3 files on
CD-ROM, CD-R or CD-RW discs.
•
The unit can read MP3 files written in the
format compliant with ISO 9660.
•
However it does not support the MP3 data
written by the method of packet write.
•
The unit can not read an MP3 file that has a
file extension other than “.mp3”.
•
If you play a non-MP3 file that has the “.mp3”
extension, you may hear some noise.
•
In this manual, we refer to what are called
“MP3 file” and “folder “ in PC terminology as
“track” and “Album,” respectively.
•
Maximum number of directory level is 8,
including the root directory. Maximum number
of files and folders per disc is 256.
•
The unit may not play tracks in the order of
Track numbers.
•
The unit plays only the audio tracks if a disc
contains both audio tracks and MP3 files.
•
When playing a disc of 8kbps or VBR*, the
elapsed playing time in the display window
will not be correct and also the intro play may
not function properly. *VBR: Variable Bit Rate
Note on creating your own CD-Rs or
CD-RWs containing MP3 files
•
To enjoy high quality sound, we recommend
converting to MP3 files with a sampling
frequency of 44.1 kHz and a fixed bit rate of
128 kbps.
•
DO NOT store more than 256 MP3 files per
disc.
•
For ISO 9660 -compliant format, the
maximum allowable depth of nested folders is
8, including the root directory (folder).
•
When CD-R disc is used, playback is possible
only for discs which have been finalized.
•
Make sure that when MP3 CD-R or CD-RW is
burned that it is formatted as a data disc and
NOT as an audio disc.
•
You should not write non-MP3 files or
unneeded folders along with MP3 files on the
disc otherwise it takes a long time until the
unit starts to play MP3 files.
•
With some CD-R or CD-RW media, data may
not be properly written depending on their
manufacturing quality.
In this case, data may not be reproduced
correctly. High quality CD-R or CD-RW disc is
recommended.
•
Up to 16 characters are displayed for the
name of an Album or a Track. ID3 TAG
version 1.x is required.
•
Note that the unit may not play Track in the
order that you wrote them to the disc.
