MP3 INTRODUCTION

ENGLISH

What is MP3?

MP3 is an abbreviation of Motion Picture Experts Group (or MPEG) Audio Layer 3. MP3 is simply a file format with a data compression ratio of 1:10 (128 Kbps*).

*Bit rate is the average number of bits that one second of audio data will consume. The unit used is Kbps. To get a better audio quality, choose a higher bit rate. The most popular bit rate for encoding is 128 Kbps.

•For details information about the MP3 discs, refer to “A Guide to MP3/WMA” (separate volume).

Compatible with ID3 Tag

Extra information data such as album title, performer name, song title, recording year, music genre and a brief comment can be stored within an MP3 file.

This unit can show both ID3v1 (Version 1) and ID3v2 (Version 2) tags on the display. (See page 20.)

•Some characters cannot be shown correctly.

•If both ID3v1 and ID3v2 are recorded on a disc, ID3v2 information will be shown.

How are MP3 files recorded and played back?

MP3 “files (tracks)” can be recorded in “folders” —in PC terminology.

During recording, the files and folders can be arranged in a way similar to arranging files and folders of computer data.

“Root” is similar to the root of a tree. Every file and folder can be linked to and be accessed from the root.

The illustration below shows an example of how MP3 files are recorded on a CD-R or CD-RW, how they are played back, and how they are searched for on this unit.

Notes:

•This unit can read a CD-ROM containing MP3 files. However, if non-MP3 files are recorded together with MP3 files, this unit will take a longer time to scan the disc. It may also cause the unit to malfunction.

•This unit cannot read or play an MP3 file without the extension code <.mp3>.

•This unit is not compatible with MP3 file encoded with Layer 1 and Layer 2 formats.

•This unit is not compatible with Playlist**.

**A playlist is a simple text file, used on a PC, which enables users to make their own playback order without physically rearranging the files.
