OPERATION

Notes on MP3/WMA Recordings

About MP3



An MP3 file is audio data compressed by using the MPEG1

audio layer-3 file-coding scheme. We call files that have the

“.mp3” file extension “MP3 files”.



The unit can not read an MP3 file that has a file extension other

than “.mp3”.

About WMA (Window Media Audio)



An WMA file is a Microsoft audio compression

technology.



WMA(Windows Media Audio) offers double the audio compres-

sion of the MP3 format.

MP3/WMA Disc compatibility with this unit is limited as

follows:

1. Sampling Frequency / only at 44.1kHz (MP3),

22.05 - 44.1kHz (WMA)

2. Bit rate / within 32 - 320kbps (MP3),

32 - 128kbps (WMA)

3. CD-R/CD-RW physical format should be “ISO 9660”

4. If you record MP3/WMA files using the software which cannot

create a FILE SYSTEM, for example “Direct-CD” etc., it is

impossible to playback MP3/WMA files. We recommend that

you use “Easy-CD Creator” which creates an ISO9660 file sys-

tem.

5. A single session disc requires MP3/WMA files in the first track.

If there is no MP3/WMA file in the 1st track, it cannot playback

MP3/WMA files. If you wish to playback MP3/WMA files, format

all the data in the disc or use a new one.

6. Folder or File names should have a maximum 22 letters or less.

ID3 TAG: Title, Artist or Album names should have a maximum

30 letters or less.

CD TEXT: Title, Artist or Album names names should have a

maximum 30 letters or less.

The file must incorporate “.mp3” or “.wma” extension e.g.

“********.MP3” or “********.WMA”.

This unit requires discs/recordings to meet

certain technical standards in order to achieve optimal playback

quality. There are many different types of recordable disc formats

(including CD-R/CD-RW containing MP3 or WMA files). That

require certain pre-existing conditions (see above) to insure com-

patible playback.

Customers should also note that permission is required in

order to download MP3/WMA files and music from the

Internet. Our company has no right to grant such permission.

Permission should always be sought from the copyright

owner.
