MP3 mode
22MP3 modeWhat are MP3 files? MP3 (MPEG 1 Audio Layer-3) is a standardised technology and format for the
compression of sound sequences. The sound file is compressed to about
1/10th of its original size. Sounds that are out of the human hearing range
are excluded while those that are within the range are compressed.Accepted recording formatsIt is possible to play MP3 files recorded on CD-ROMs, CD-Rs and CD-RWs.
The unit accepts MP3 discs that have been formatted using the ISO 9660
standard level 1 or 2. The unit can also play discs recorded using the Romeo
or Joliet standard.
The unit will not play CDs recorded using “Packet Writing” (UDF or Direct CD
formats) whether this has been used on the entire disc or within a session. In
this case the display will display an error message and will eject the CD.
ISO 9660 format
This is the most common of international standards for the format logic of
files and folders on a CD-ROM.
There are different levels of specification. For level 1, the names must be in
8.3 format (8 characters maximum for the name of the file + 3 characters for
the extension “.MP3”. Folder names cannot be more than 8 letters long. On
the contrary, Level 2 specifications allow up to 31 characters.
Multi-session CDs This method of recording means that information may later be added to the
CD (while there is enough space remaining and the CD is not closed). The
information on each recorded CD is contained within an area marked by two
data labels called “Lead-in” for the beginning of the session and “Lead-out”
for the end. A multi-session CD will allow for multiple segments that contain
their own “Lead-in” and “Lead-out”.
Information from the ID3 data fieldThe ID3 data of an MP3 file contains information on the Artist, Album and the
name of the track.
This unit can display the information from the ID3 data field, versions 1 and
2, to a maximum of 60 characters in total.
Note
•When an MP3 disc is being played it is possible that some songs may not
play or may be played incorrectly. This may be due to the configuration of the
disc, the software or the hardw are used for the recording.•Audio CDs (CD-DA) meet the specifications and carry their corresponding
symbol. Those CDs with copyright protection do not meet these specifica-
tions and do not bear the corresponding symbol; for this reason there may be
errors in reading this type of disc.•For MP3 CDs, the MP3 data rate should oscillate between 8 and 320
Kb/sec.•It is possible to read multi-session discs but if the data has been recorded
in both formats (CD-DA and MP3), regardless of the order, only the audio
tracks will be played.
