• What is MP3?
MP3 (MPEG Audio Layer3) is a standard format of audio compression technology.
Use of MP3 enables data compression to a maximum of 1/10 the size of CD data.
•
Standard for playable MP3 files
•
Generally, higher bit rates generate higher sound quality. Use of discs recorded at a bit rate
of 128 kbps for MP3 is recommended to enjoy listening to music at a constant sound quality.
•
VBR (variable bit rate) is supported as the bit rate.
•
Neither free-format nor lossless compression format is supported.
* Extremely large or small files may not playback normally
•
Available media
•
Media which can be used for playback of MP3 discs is CD-R and CD-RW.
* Some types of CD-R or CD-RW are unplayable because of their higher sensitivity to
hot and humid environments compared to a normal music CD. In addition, discs with
fingerprints or scratches on them may not playback properly or the sound may jump.
• Some types of CD-R or CD-RW may deteriorate when left in a vehicle environment for a
long time.
* CD-R and CD-RW are UV-sensitive media, therefore storing them in a lightproof
package is recommended.
• File name

be recognized as MP3 files and played by the system.
•
Save MP3 files using the file extension “MP3”.
