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 infor-
mation can include the track title, the artist’s
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 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 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
(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.
Romeo:
File names can have up to 128 characters.

m3u

Playlists created using the “WINAMP” software
have a playlist file extension (.m3u).

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.

MP3

MP3 is short for MPEG Audio Layer3. It is an
audio compression standard set by a working
group (MPEG) of the ISO (International
Standards Organization). MP3 is able to com-
press audio data to about 1/10th the level of a
conventional 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 prioritizes
sound quality.
