About the MP3/WMA/AAC
files
What is MP3/WMA/AAC?
MP3, WMA, and AAC are audio compression
methods which have become standard
formats.
MP3 is an audio compression method
and classified into audio layer 3 of MPEG
standards.
WMA (Windows Media Audio) is an audio
compression method developed by Microsoft
Corporation.
AAC (Advanced Audio Coding) is a newer
audio compression method developed for
used with video compression standards
MPEG-2 and MPEG-4, and has been adopted
as the standard audio format of the iPod and
iTunes by Apple Inc.
These features compress the original audio
data to about 10 percent of its initial size with
a high sound quality. This means that about
10 music CDs can be recorded on a CD-R/
RW disc to allow a long listening time without

having to change CDs.
Displaying MP3/WMA/AAC Tag
titles
Tag information such as title, artist and album
title can be displayed for an MP3/WMA/AAC
file containing Tag information.
This system supports ID3 Tag ver. 1.x/2.x
and WMA Tag.
This system supports the tag titles up to
30 bytes for ID3 Tag ver. 1.x, and up to 60
bytes for ID3 Tag ver. 2.x and WMA tag.
Precautions on MP3/WMA/AAC
data
Files with other than MP3/WMA/AAC data
cannot be played. In addition, some files
may not be played because of the encoding
format. When a file cannot be played, the
next file is played instead.
Some noise may occur depending on the
type of encoder software used to encode
the data.
Files encoded in VBR (variable bit rate)
format may not be played. In the case of
data recorded in VBR format, the displayed
play time may be slightly different from the
actual play time.
Tag information entered with 2-byte
characters may not be displayed properly.
Files with DRM cannot be played.
Add a file extension “.MP3” or “.mp3” to an
MP3 file, “.WMA” or “.wma” to a WMA file,
and “.M4A” or “.m4a” to an AAC file using
single byte characters. If you add other file
extension or forget to add the file extension,
the file cannot be played.
