MP3 Overview
MP3 Overview
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
1000.
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
T o e n j o y h i g h q u a l i t y s o u n d , w e
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 1000 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 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 CD-R otherwise it takes a long time
until the unit starts
to play MP3 files.
With some CD-R 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 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 tracks in
the order that you wrote them to the disc.
