■Operating tips for MP3
●
This audio system handles MP3 files that
have been recorded on CD-R/CD-RW/CD-
ROMs. Discs that have been recorded
using the following formats can be played:
• ISO 9660 level 1
• ISO 9660 level 2
• Joliet extended format
• Romeo extended format
● This unit handles MP3 files conforming to
the MP3 format containing both header
frames and data frames.
● If a disc has both music data (CD-DA) and
MP3 files, playback of the two file types
differs depending on how the disc was
recorded.
● Packet written discs cannot be played on
this unit.
● This unit does not play CDs recorded
using MP3i (MP3 interactive), MP3 PRO
and RIFF MP3 formats. Specialized glossary
MP3
Abbreviation for “MPEG Audio Layer 3”.
A technical standard for audio compression
as decided by an ISO (International
Organization for Standardization) MPEG
working group.
Use of MP3 allows for audio data to be
compressed to approximately a tenth of the
source data size.
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels based
on differences in file naming procedures,
data configuration and other characteristics.
Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an MP3
file, the more information regarding musical
reproduction it carries, and therefore the
better the sound quality.
Packet writing
A general term for the method, similar to that
used for floppy discs or hard drives, of
recording the required file in a single
increment on a CD-R and similar.
