MP3/WMA Player

What is MP3/WMA?

MP3 (MPEG Audio Layer-3) and WMA (Windows Media
Audio) are the compression formats of digital audio. The
former is developed by MPEG (Motion Picture Experts
Group), and the latter is developed by Microsoft
Corporation. Using these compression formats, you can
record the contents of about 10 music CDs on a single
CD media (This figures refer to data recorded on a 650
MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a
sampling frequency of 44.1 kHz).

Note: MP3/WMA encoding and writing software is not
supplied with this unit.

Points to remember when making MP3/WMA files

Common

¡ High bit rate and high sampling frequency are recom-

mended for high quality sounds.

¡ Selecting VBR (Variable Bit Rate) is not recommended

because playing time is not displayed properly and
sound may be skipped.

¡ The playback sound quality differs depending on the

encoding circumstances. For details, refer to the user
manual of your own encoding software and writing
software.

MP3

¡ It is recommended to set the bit rate to “128 kbps or

more” and “fixed”.

WMA

¡ It is recommended to set the bit rate to “64 kbps or

Notes on MP3/WMA

more” and “fixed”.

¡ Do not set the copy protect attribute on the WMA file

to enable this unit to play back.

also damage your hearing.

CQ-C7403U/C7303U/C7203U/C7103U

Recording MP3/WMA files on a CD-media

¡ You are recommended to minimize the chances of

making a disc that contains both CD-DA files and
MP3/WMA files.

¡ If CD-DA files are on the same disc as MP3 or WMA

files, the songs may not play in the intended order,
or some songs may not play at all.

¡ When storing MP3 data and WMA data on the same

disc, use different folders for each data.

¡ Do not record files other than MP3/WMA files and

unnecessary folder on a disc.

¡ The name of an MP3/WMA file should be added by

rules as shown in the following descriptions and also
comply with the rules of each file system.

¡ You may encounter trouble in playing MP3/WMA files

or displaying the information of MP3/WMA files
recorded with certain writing software or CD
recorders.

Compression formats

(Recommendation: “Points to remember when making MP3/WMA files” on the previous page)

¡ The file extension “.mp3” or “.wma” should be

assigned to each file depending on the file format.

¡ This unit does not have a play list function.
¡ Although Multi-session recording is supported, the

use of Disc-at-Once is recommended.
