Descriptions of MP3 En An MP3 file stores audio data compressed using MPEG1/2, the audio layer-3 file-coding scheme. In this manual, CDs, CD-R discs and CD-RW discs are all referred to as "discs". We refer to what are called "folder" and "file" in PC terminology as "album" and "track". Notes on playing MP3 files •An MP3 track must be recorded on a disc in the format compliant with ISO 9660. Note, however, that the unit may not play tracks in the order they were recorded. •The maximum allowable number of tracks and albums in a disc are as follows: - number of tracks: 255 - number of albums: 255 •The maximum allowable depth of nested albums is 8. •It may take 30 seconds or more before the unit can start play of MP3 tracks, depending on the number of recorded tracks and the complexity of the album tree. •This unit supports a multi-session discs; however, for a multi-session disc mixed with CD-DA tracks and MP3 tracks, it plays only one session. •The unit cannot play MP3 tracks recorded using a packet writing utility. •The unit can play MP3 tracks having a file extension ".mp3". •If you play a non-MP3 track that has the ".mp3" file extension, you may hear some noise. Notes on display indications during play •Up to 64 characters (in ASCII code) are displayed for the title of an album or a track. If ID3TAG version 1.X was applied to record additional information for an MP3 track, up to 30 characters showing track title is displayed. This unit does not support ID3TAG version 2.X. character codes wthich cannot be represented in ASCII code are displayed as " ". • The elapsed playing time may not be displayed correctly for MP3 tracks. Terminology •ISO 9660 ISO stands for the "International Organization for Standardization". ISO 9660 determines the file structure for the CD-ROMs. This unit can play MP3 files recorded in the format compliant with ISO 9660. •Nesting of folders (albums) To organize data files stored in a PC, you can store related files in a folder. A folder can contain other folders as well as files. For example, folder A can contain folder B, and folder B can contain folder C; this is called "nesting of folders". The maximum depth of nested folders, allowed by ISO 9660, is 8. •Writing utilities There are 3 utilities used to record data on a disc. 1.DAO (Disc At Once) utility All data to be written must be prepared in advance and written onto a disc from the beginning to the end in one operation. No data can be added to a disc on which data were already written with DAO utility. 2.TAO (Track At Once) utility Data are written onto a disc track by track. Data can be added to a disc on which data were written with TAO utility. 3.Packet writing utility Tracks are divided into smaller pieces while being recorded, depending on the size of available spaces on the disc. Data can be added to a disc on which data were written with packet writing utility. This unit can play MP3 discs recorded using DAO and TAO utilities. •ID3TAG ID3TAG determines the data format for the text to be added to an MP3 file, mainly used to indicate a track title or an artist's name, etc. Notes on creating MP3 discs •When converting audio data to MP3 The unit supports MP3 files with a sampling frequency of 16, 22.05, 24, 32, 44.1 or 48 kHz. To enjoy high sound quality, we recommend storing MP3 files with a sampling frequency of 44.1 kHz and a fixed bit rate of 128 kbps. The assured bit rate range for sound quality on the unit is 8 kbps to 320 kbps. If an MP3 files stored with a bit rate beyond that range is played back, sound quality is not guaranteed and noise may be generated. •When creating MP3 discs Do not store more than 255 albums in a disc. Also, keep the total number of albums and tracks 255 or less in a disc. 14
