CD/MP3/WMA/AAC Operations
This system can playback MP3/WMA/AAC files recorded on a disc.
About the MP3/WMA/AAC files
What is MP3/WMA/AAC?
MP3, WMA, and AAC are the audio file formats
which have penetrated into PC users and
become a standard format.
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
compre
ssion 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 audio
CDs c
an 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 (track title, artist name, and
album title) can be displayed for an MP3/WMA/
AAC file containing the Tag information.
This system supports the ID3 TAG version 1.x/
2.x and WMA-TAG.
Note:
• Tag information entered with 2-byte characters
may not be displayed properly on the display.
• The ID3 version 2.x tag format is not completely
supported. This system can display information up
to 60 bytes, and ignores the rest.
• Album titles of WMA-TAG may not be displayed
properly.
Precautions on the MP3/WMA/AAC
files
● General precautions
•Files other than MP3/WMA/AAC format cannot
be played. In addition, some files may not be
played because of the encoding settings.
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.
•You can apply the VBR (Variable Bit Rate)
format when encoding. In this cas e, the
displa
yed play time may be slightly different
from the actual play time.
•Files that the DRM (Digital Rights
Management) function is set cannot be played.
● For MP3 files
• Set the Sampling Frequency to:
• MPEG1 Layer3: 32, 44.1, or 48 kHz
• MPEG2 Layer3: 16, 22.05, or 24 kHz
• MPEG2.5 Layer3: 8, 11.025, or 12 kHz
• Set the Bit Rate to:
• MPEG1 Layer3: 32 to 320 kbps (VBR)
• MPEG2 Layer3: 8 to 160 kbps
(VBR)
• MPEG2.5 Layer3: 8 to 160 kbps (VBR)
•Add a file extension “.MP3” or “.mp3” using
single byte characters.
● For WMA files
• Set the Sampling Frequency to within ranges
from 22.05 to 44.1 kHz.
• Set the Bit Rate to 48, 64, 80, 96, 128, 160, or
192 kbps.
