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.

ID3 tag

This is a method of embedding track-related

information in a MP3 file. This embedded in-

formation can include the track title, the ar-

tists 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.

ISO9660 format

This is the international standard for the for-

mat logic of CD-ROMfolders 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 con-

sists of up to 8 characters, half-byte English

capital letters and half-byte numerals and the

_ sign, with a file-extension of three charac-

ters.)

Level 2:

The file name can have up to 31 characters (in-

cluding the separation mark . and a file ex-

tension). Each folder contains less than 8

hierarchies.

Extended formats

Joliet:

File names can have up to 64 characters.

Romeo:

File names can have up to 128 characters.

m3u

Playlists created using the WINAMP soft-

ware have a playlist file extension (.m3u).

MP3

MP3 is short for MPEG Audio Layer 3. It is an

audio compression standard set by a working

group (MPEG) of the ISO (International Stan-

dards Organization). MP3 is able to compress

audio data to about 1/10th the level of a con-

ventional disc.

Multi-session

Multi-session is a recording method that al-

lows 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-ses-

sion is a method of recording more than 2 ses-

sions in one disc.

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.
