Playing Back MP3 Discs on 3-CD Changer

About 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*). That means, by using MP3 format, one CD-R or CD-RW can contain 10 times as much data volume as a regular CD can.

*Bit rate is the average number of bits that one second of audio data will consume. The unit used is kbps (1024 bits/second). To get a better audio quality, choose a higher bit rate. The most popular bit rate for encoding and the most recommended for this 3-CD Changer is 128 kbps.

Compatible with ID3v1

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 track.

3-CD Changer can show ID3v1 tags (album title, performer name and song title) on the display.

•Some characters cannot be shown correctly.

•3-CD Changer is not compatible with ID3v2.

•If a disc is recorded with multiple sessions, only the first session can be played back. However if a session is not closed (not finalized), it cannot be played back.

MP3 Disc Structure

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

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

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

Playback order, track search order, and group search order of the MP3 tracks recorded on a disc are determined by the writing (or encoding) application; therefore, playback order may be different from the one you have intended while recording the groups and the tracks.

The illustration below shows an example of how MP3 tracks are recorded on a CD-R or CD-RW, how they are played back, and how they are searched for on this 3-CD Changer.
