MP3 overview
Notes 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 8 kbps 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.
Notes 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 o f 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
