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-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 (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.
38
En
HHHHHHHHHHHHHH
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.
