What is MP3/WMA

MP3 is an audio compression method

and classied into audio layer 3 of MPEG

standards.

WMA is an audio compression method

developed by Microsoft Corporation.

These audio compression methods have

penetrated into PC users and become a

standard format.

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

disc or CD-RW disc to allow a long listening

time without having to change CDs.

Note: Some CDs recorded on CD-R/RW

mode may not be usable.

Displaying MP3/WMA TAG titles

Tag information such as title, artist and

album title can be displayed for MP3/WMA

le containing Tag information.

WMA le

Usablesamplingratesandbitrates

1. MP3: Sampling rate 8 kHz-48 kHz, Bit rate

8 kbps-320 kbps / VBR

2. WMA: Bit rate 8 kbps-320 kbps

File extensions

1. Always add a file extension “.MP3”,

“.WMA” to MP3, WMA le by using single

byte letters. If you add a file extension

other than specified or forget to add the

le extension, the le cannot be played.

2. Files without MP3/WMA data will not play.

The les will be played soundlessly if you

attempt to play files without MP3/WMA

data.

* When VBR les are played, the play time

display may differ the play location.

* When MP3/WMA les are played, a little

no sound part is caused between tunes.

Logicalformat(Filesystem)

When writing MP3/WMA le on a CD-R disc

or CD-RW disc, please select “ISO9660 level

1, 2 or Joliet or Romeo” or Apple ISO as the

writing software format. Normal play may not

be possible if the disc is recorded on another

format.

Folderstructure

A disc with a folder having more than 8

hierarchical levels will be impossible.

Numberoflesorfolders

1. Up to 999 files can be recognized per

folder.

Up to 6000 les can be played.

2. Tracks are played in the order that they

were recorded onto a disc. (Tracks

may not always be played in the order

displayed on the PC.)

3. Some noise may occur depending on

the type of encoder software used while

recording.

PlayingMP3folders

When selected for play, files and folders

(Folder Search, File Search or Folder Select)

are accessing in the order in which they were

written to the media.

As a result, the order in which they are

expected to be played may not match the

order in which they are actually played.

You may be able to set the order in which

MP3/WMA les are to be played by assigning

file names beginning with play sequence

numbers such as “01” to “99”.

For example, a medium with the following

folder/file hierarchy is subject to Folder

Search, File Search or Folder Select.
