MP3 CD-R Disc

MP3 Format

The MP3 player will only play CD-R discs. It can read and play a maximum of:

    • 50 folders
    • 11 folders in depth
    • 50 playlists
    • 10 sessions
    • 255 files

All folders, playlists, sessions and files over the maximum are ignored.

Record an MP3 disc:

    • Onto a CD-R disc.
    • Record playlists with an .m3u or .wpl extension.
    • Do not mix standard audio and MP3 files on the same disc.
    • Record the entire disc at once.
    • Finalize the disc when recording an MP3 disc with multiple sessions.

Root Directory

The root directory is treated as a folder. All .mp3 files in the root directory are accessed before folders in the root directory.

Empty Directory or Folder

Empty folders and directories do not display. The system ignores empty directories and folders and advances to the next directory or folder that has .mp3 files in it.

No Folder

On a CD that contains only .mp3 files in the root directory the next and previous folder functions do not work.

On a CD that contains playlists and .mp3 files the next and previous folder functions search playlists first and then search .mp3 files in the root folder.

Order of Play

CDs that have playlists play the tracks in the following order:

  1. After the first track in the first playlist ends, play continues sequentially through all tracks in each playlist
  2. After the last track of the last playlist ends, play restarts from the first track of the first playlist.

CDs that do not have playlists play the tracks in the following order:

  1. The first file in the root directory plays.
  2. After all files from the root directory have played, files in the folders play.
  3. After playing the last file from the last folder, play restarts with the first file in the root directory.

File System and Naming

The radio display shows, track names that are shorter than 39 characters. Names that are longer are shortened. The track name appears as:

    • The song name that is in the ID3 tag.
    • The file name without the file extension if the song name is not in the ID3 tag.

Preprogrammed Playlists

Playlists are accessed before files or folders in the root directory.

Preprogrammed playlists created by WinAmp™, MusicMatch™, or Real Jukebox™ software can be accessed and are treated as special folders containing compressed audio song files.

Music Navigator

The music navigator feature lets MP3 CDs play in order by artist or album.

    • The MP3 player scans the disc to sort the files by artist and album ID3 tag information.
    • It can take several minutes to scan the disc depending on the number of MP3 files recorded to the CD-R.
    • The radio starts playing while the disc is being scanned.
    • After the scan is finished, the disc starts playing.
