”
This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
”
This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track title, the artist’s name, the album
title, the music genre, the year of produc-
tion, comments and other data. The con-
tents 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 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.
”
This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are two
levels of regulations.
”
Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
”
Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies.
”
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
”
MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
”
WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®
. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8,
and 9.
