Notes on MP3

This player allows you to play MP3 ﬁles recorded on CD-ROMs, CD-Rs (recordable)

and CD-RWs (rewritable).

What is MP3?

MP3, short for MPEG Audio Layer-3, is a standard for compressing digital video data adopted for video CDs

and similar media. It is one of the audio compression schemes covered by MPEG’s (Motion Picture Experts

Group) digital audio compression standards. What it does is reduce the number of bytes in a song without

hurting the sound quality by means such as eliminating big sound waves within in the sound range that is im-

perceptible to the human ear. This compression allows you to reduce the contents of a conventional music CD

by a factor of around 10. This means that you can record the contents of 10 music CDs on a single CD-R or

CD-RW. (The ﬁgures refer to data recorded on a 650 MB CD-R or CD-RW at a ﬁxed bit rate of 128 kbps and a

sampling frequency of 44.1 kHz.)

Points to Remember When Recording an MP3 Disc

❐ Converting (encoding) audio data to an MP3 ﬁle

≥ It is recommended to set the bit rate to “128 kbps or more” and “Fixed”.

≥ Bit rate 8 kbps of MPEG 2 and sampling frequency 16 kHz of MPEG 2 cannot be reproduced.

≥ If set to VBR (Variable Bit Rate), the ﬁle playing time may not be displayed correctly.

≥ The playback sound quality differs depending on the encoding software and the bit rate. For details, refer to

the user manual of your encoding software.

❐ Recording MP3 ﬁles on CD-R/RW

≥ Do not record ﬁles other than MP3s or unnecessary folders on a disc.

If too many folders or ﬁles other than MP3s are recorded on a disc, it may take some time before playback

starts, and you may have difficulties using fast forward and fast reverse.

≥ Use ISO 9660 ﬁle system (Extension of the ISO 9660 ﬁle systems are included.) (➡ page 43). APPLE HFS

ﬁle system is not supported.

If they do not conform to ISO 9660 ﬁle system, the ﬁle may not play normally, or the ﬁle or folder names

may not be displayed correctly.

≥ Make sure to add the “.mp3” extension to each MP3 ﬁle name.

A ﬁle with a different ﬁle name extension or none at all will not play.

≥ Although Multi-session recording is supported, the use of Disc-at-Once is recommended.

Make sure to close the session when you ﬁnished recording on a disc.

≥ ID3Tags are not supported.

The song information is stored but not displayed. Discs written with ID3 Ver. 2 may not work properly.

≥ Packet writing software is not supported.

≥ A playlist function is not supported.

Record ﬁles and folders in the order in which you want them to be played. Some writing software lets you

specify the recording order by adding a preﬁx in the range of “01”j“09”, etc. to the ﬁle name. For details,

refer to the use manual of your writing software.

Note:

≥ You may encounter trouble in playing MP3s or displaying the information of MP3 ﬁles recorded with certain

writing software or CD recorders (CD-R/RW drives).

Note:

≥ MP3 encoded software and writing software are not supplied to this model.

Caution:

≥ Never assign the “.mp3” ﬁle name extension to a ﬁle that is not in the MP3 format. This may not only pro-

duce noise from the speakers and speaker damage, but can damage your hearing.

❐ Maximum Number of Files/Folders

❐ Supported File Systems and File Names

≥ Maximum number of trees: 8

≥ Maximum number of ﬁles/folders: 254 (ﬁlesifolders. Root folder is not included.)

The most common international standard for the

logical format for ﬁles and directories.

APPLE HFS

The ﬁle system used by the Macintosh operating

Multi-session

A method of adding data incrementally to a CD-R or

CD-RW in more than one recording session.

Disc-at-Once

A method of writing data in a media by just one op-

eration and no more writing after that.
