MP3 files

! MP3 is short for MPEG Audio Layer 3 and refers to an audio compression technology standard. ! This unit allows playback of MP3 files on CD-ROM, CD-R and CD-RW discs. Disc re-
cordings compatible with level 1 and level 2 of ISO9660 and with the Romeo and Joliet file system can be played back. It is possible to play back multi-session compatible recorded discs. MP3 files are not compatible with packet write data transfer. The max. number of characters which can be displayed for a file name, including the extension (.mp3), is 32 characters from the first character. The max. number of characters which can be displayed for a folder name is 32 characters. In case of files recorded according to the Romeo and Joliet file system, only the first 32 characters can be displayed. When playing discs with MP3 files and audio data (CD-DA) such as CD-EXTRA and MIXED-MODE CDs, both types can be played only by switching mode between MP3 and CD-DA. The folder selection sequence for playback and other operations becomes the writing sequence used by the writing software. For this reason, the expected sequence at the time of playback may not coincide with the actual playback sequence. However, there also is some writing software which permits setting of the playback order. Files are compatible with the ID3 Tag Ver. 1.0 and Ver. 1.1 formats for display of album (disc title), track (track title) and artist (track artist). Only when MP3 files of 32, 44.1 and 48 kHz frequencies are played back, the emphasis function is valid. (16, 22.05, 24, 32, 44.1, 48 kHz sampling frequencies can be played back.) There is no m3u playlist compatibility. There is no compatibility with the MP3i (MP3 interactive) or mp3 PRO format. The sound quality of MP3 files generally becomes better with increasing bit rate. This unit can play recordings with bit rates from
8 kbps to 320 kbps, but in order to be able to enjoy a certain sound quality, it is recommended to use only discs recorded with a bit rate of at least 128 kbps.
Important ! When naming an MP3 file, add the corresponding filename extension (.mp3). ! This unit plays back files with the filename extension (.mp3) as an MP3 file. To prevent noise and malfunctions, do not use this extension for files other than MP3 files.

1 First level

2 Second level 3 Third level
Notes ! This unit assigns folder numbers. The user can not assign folder numbers. ! It is not possible to check folders that do not include MP3 files. (These folders will be skipped without displaying the folder number.) ! MP3 files in up to 8 tiers of folders can be played back. However, there is a delay in the start of playback on discs with numerous tiers. For this reason we recommend creating discs with no more than 2 tiers. ! It is possible to play back up to 253 items from folder on one disc.

This expresses data volume per second, or bps units (bits per second). The higher the rate, the more information is available to reproduce the sound. Using the same encoding method (such as MP3), the higher the rate, the better the sound.
Romeo: File names can have up to 128 characters.
Playlists created using the WINAMP software have a playlist file extension (.m3u).

MP3 ID3 tag

This is a method of embedding track-related information in a MP3 file. This embedded information can include the track title, the artists name, the album title, the music genre, the year of production, comments and other data. The contents can be freely edited using software with ID3 Tag editing functions. Although the tags are restricted to the number of characters, the information can be viewed when the track is played back. MP3 is short for MPEG Audio Layer 3.

MP3 is able to compress audio data to about 1/10th the level of a conventional disc.
