HHHHHHHHHHHHHH Additional Information Appendix Terms Bit rate 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. English m3u 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. It is an audio compression standard set by a working group (MPEG) of the ISO (International Standards Organization). MP3 is able to compress audio data to about 1/10th the level of a conventional disc. Multi-session Multi-session is a recording method that allows additional data to be recorded later. When recording data on a CD-ROM, CD-R or CD-RW, etc., all data from beginning to end is treated as a single unit or session. Multi-session is a method of recording more than 2 sessions in one disc. ISO9660 format This is the international standard for the format logic of CD-ROM folders and files. For the ISO9660 format, there are regulations for the following two levels. Level 1: The file name is in 8.3 format (the name consists of up to 8 characters, half-byte English capital letters and half-byte numerals and the _ sign, with a file-extension of three characters.) Level 2: The file name can have up to 31 characters (including the separation mark . and a file extension). Each folder contains less than 8 hierarchies. Extended formats Joliet: File names can have up to 64 characters. Packet write This is a general term for a method of writing on CD-R, etc. at the time required for a file, just as is done with files on floppy or hard discs. VBR VBR is short for variable bit rate. Generally speaking CBR (constant bit rate) is more widely used. But to flexibly adjust the bit rate according to the needs of audio compression, it is possible to achieve compression priorities sound quality. En 41
