Playing MP3 Files
What is MP3?
A method of compressing audio. MPEG Audio Layer 3
(MP3) allows audio to be reduced to up to one tenth its
original size when a compression rate of 128 kbps is used,
without overtly hurting audio quality.
When creating MP3 files to play on
this unit
•
Disc formats: ISO9660 level 1 and level 2
(except for extended formats)
Files: MP3 files with the suffix “.mp3” or “.MP3”
•
To play in a certain order
Prefix the folder and file names with 3-digit numbers in
the order you want to play them.
Files may not be recorded in numbered order if the
prefixes have different numbers of digits.
For example: 1????.mp3, 2????.mp3, 10????.mp3.
However, some writing software may also cause
recording to occur in a different order.

Limitations on MP3
•
This unit cannot play files if they have a suffix other than
“.mp3” or “.MP3”.
•
This unit cannot play files that have the suffix “.mp3” or
“.MP3” if they are not MP3 files.
•
This unit is compatible with multi-session but if there are
a lot of sessions it takes more time for play to start. Keep
the number of sessions to a minimum to avoid this.
•
This unit cannot play files recorded using packet write.
•
This unit can display album and track titles with ID3 tags
(version 1.0 and 1.1). Titles containing text data that the
unit doesn’t support cannot be displayed.
•
When both MP3 and CD-DA data is recorded on the disc
over a number of sessions:
•
If the first session is MP3, the unit will play from the
MP3 recordings made in that session till the session
before the first CD-DA recordings.
•
If the first session is CD-DA, the unit will play only the
recordings made in that session. The subsequent
sessions will be ignored.
