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

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 audio

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 (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 case, the

displayed 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.

• Add a file extension “.WMA” or “.wma” using

single byte characters.

files encoded by the iTunes.
