MP3 operations
The DVG-399KK can play back MP3’s files recorded to CD-ROM, CD-R or CD-RW discs.
Notes on MP3 Discs
An MP3 file stores audio data that has been compressed using the MPEG1 encoding scheme. Although PC terminol
-
ogy regarding MP3s and storage is, “files” and “folders”, in this manual we refer to them as “tracks and albums”.
Notes on Playing MP3s
- An MP3 track must be recorded on a disc in the format compliant with ISO9660. Track order may differ from MP3
player to MP3 player.
- The maximum allowable number of tracks and/or albums located on a disc is 900, including the root albums (direc-
tory).
- The maximum allowable depth of a nested folder is 127, including files.
- If a disc contains both audio as well as MP3 tracks, it will not play in the DVG-399K.
- Multi-session discs are limited to a total of 20 sessions.
- MP3 playback is optimal with MP3s encoded with a sampling rate of 44.1 kHz and a fixed bit rate of128 kbps.
- The unit may not play MP3 tracks recorded using a packet writing utility.
- The unit can only play back MP3 tracks having a file extension of “.mp3”.
- It may take 30 seconds or more before the unit can start playback of MP3’s. This time depends on the
number of recorded tracks and the complexity of the album tree.
- If you play a non-MP3 track that has the “.mp3” file extension, the unit will skip to the next valid track automatically.
- Digital recordings with this unit cannot be done while playing back MP3 discs.
Notes on display indications during playback
- Up to 8 characters are displayed for the name of an album or track.
- Characters other than uppercase letters (“A” to “Z”), numerals (“0” to “9”) and underscore (“_”) may not be dis-
played, or may be displayed in different characters.
- The elapsed playing time may not be displayed correctly for MP3 tracks.
- Depending on the condition of the recording equipment or the CD-R/RW disc itself, a false album or track which
cannot by played on the unit may be displayed on a TV screen.
Notes on creating MP3 discs
- When converting audio data to MP3, create MP3 files with a sampling frequency of 44.1 kHz and a fixed bit rate of
128 kbps.
- When creating MP3 discs, do not store more than 900 albums and/or tracks in a disc.
- To play tracks in the order they were recorded, ensure your encoding software is set up to auto arrange by name,
or use only one album (if they are already alphabetized) or place a three digit number in front of each track to set an
order manually.
