ID3 Tag—
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 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.
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.
iTunes Tag—
AAC files allow you to attach text information
called iTunes tag to display track titles and
album titles. iTunes tags can be entered
with Apple iTunes.

Playlists created using "WINAMP" software
have a playlist file extension (.m3u).
MP3—
MP3 is an audio compression standard
determined by a working group (MPEG)
of
the
ISO
(International

MP3 compresses audio
data to about 1/10 the size of that on
conventional discs.
WMA—
WMA (Windows Media Audio) is an
audio
compression
by Microsoft. It compresses files into a
size smaller than that of MP3 files. The
decoding formats for WMA files are Ver. 7,

AAC—
AAC (Advanced Audio Coding) is an
audio compression standard determined
by a working group (MPEG) of the ISO
(International Standard Organization).

compression rate than MP3 files, but their
sound quality is almost the same as that of
MP3 files. The AAC file format supported
by this system is the MPEG4 AAC format,
and Apple iTunes is required to create
MPEG4 AAC files.
