6. TIPS FOR OPERATING THE AUDIO/VISUAL SYSTEM

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 number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a 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
and artist name.
 This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are 2 lev-
els 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.

MP3/WMA/AAC FILES
MP3 (MPEG Audio LAYER3) is a stan-
dard audio compression format. Files
can be compressed to approximately
1/10 of their original size by using MP3
compression.
WMA (Windows Media Audio) is a
Microsoft audio compression format.
This format compresses audio data to
a size smaller than that of the MP3 for-
mat.
AAC (Advanced Audio Coding) is a
standardized the audio compression
type that is designed to be the succes-
sor of the MP3 format. AAC generally
achieves good sound quality and high-
compression than MP3 at similar bit
rates.
There is a limit to the MP3, WMA and
AAC file standards and to the media/
formats recorded by them that can be
used.
