TERMS
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 di scs.
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 methods (such as MP3/WMA),
the higher the rate, the better the sound.
Multisession—
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 be-
ginning to end is treated as a single unit
or session. Multi −session is a method of
recording more than 2 sessions in one
disc.
CDDA—
CD− DA is an abbreviation of Compact
Disc Digital Audio. It refers to the uncom-
pressed format of regular CDs. ID3 Tag—
This is a method of embedding track
−re-
lated information in an MP3 file. This em-
bedded information can include the track
title, the artist’s name, the album title, the
music genre, the year of production, com-
ments 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.
WMA Tag—
WMA files can contain a WMA tag that is
used in the same way as an ID3 tag.
WMA tags carry information such as track
title, artist name.
ISO 9660 format—
This is the international standard for the
format logic of CD −ROM folders and files.
For the ISO 9660 format, there are regula-
tions 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 nu-
merals and the “ −” sign, with a file exten-
sion of three characters.) Level 2:
The file name can have up to 31 (MP3
files)/15 (WMA files) characters (including
the separation mark “.” and a file exten-
sion). Each folder contains less than 8
hierarchies.
Extended formats
Joliet:
File name can have up to 64 characters.
Romeo:
File names can have up to 128 charac-
ters.
m3u—
Playlists created using the “WINAMP” soft-
ware have a playlist file extension (.m3u).
MP3—
MP3 is short for MPEG 1 & 2 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 1/10 the level of a conventional
disc.
