CD/MP3 Operations
What is MP3?
MP3 is an audio compression method and clas-
sified into audio layer 3 of MPEG standards.
This audio compression method has penetrated
into PC users and become a standard format.
This MP3 features the original audio data com-
pression to about 10 percent of its initial size with
a high sound quality. This means that about 10
music CDs can be recorded on a CD-R disc or
CD-RW disc to allow a long listening time with-
out having to change CDs.
Precautions when creating MP3 disc
● Usable sampling rates and bit rates:
1. MP3: Sampling rate 8k Hz-48 kHz,
Bit rate: 8 kbps-320 kbps / VBR
● File extensions
1. Always add a file extension “.MP3” to MP3
file by using single byte letters.
If you add a file extension other than speci-
fied or forget to add the file extension , the
file cannot be played.
2. Files without MP3 data will not play.
The indication “– –:– –” appears in the play
time display if you attempt to play files with-
out MP3 data.
● Logical format (File system)
1. When writing MP3 file on a CD-R disc or CD-
RW disc, please select “ISO9660 level 1, 2 or
JOLIET or Romeo” as the writing software
format. Normal play may not be possible if
the disc is recorded on another format. This
equipment does not support packet writing.
2. The folder name and file name can be dis-
played as the title during MP3 play but the
title must be within 64 single byte alphabeti-
cal letters and numerals (including an exten-
sion). 32 characters when written in JOLIET
format.
3. Do not affix a name to a file inside a folder
having the same name.
● Folder structure
1. A disc with a folder having more than 8
hierarchical levels will be impossible.
● Number of files or folders
1. Up to 256 files (total number of folder and file)
can be played. The root folder is counted as
one folder.
2. Tracks are played in the order that they were
recorded onto a disc. (Tracks might not al-
ways be played in the order displayed on the
PC.)
3. Some noise may occur depending on the type
of encoder software used while recording.
