Notes on MP3/WMA

❐What is MP3/WMA?

❐Recording MP3/WMA files on a CD-media

H

MP3 (MPEG audio layer 3) and WMA (Windows MediaTM 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 sin- gle 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 are not supplied with this unit.

≥CD writing software is not supplied with this unit.

❐Points to remember when making MP3/WMA files

≥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 in-

tended 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.

≥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.

≥The file extension “.mp3” or “.wma” should be assigned to each file depending on the file format.

≥This unit does not have the play list function.

≥Although Multi-session recording is supported, the use of Disc-at-Once is recommended.

Supported file systems

≥High bit rate and high sampling frequency are

recommended for high quality sounds.

≥Selecting VBR (Variable Bit Rate) is not recom-

mended because playing time is not displayed

MP3

≥It is recommended to set the bit rate to “128 kbps or more” and “fixed”.

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.

≥It is recommended to set the bit rate to “64 kbps or more” and “fixed”.

≥Do not set the copy protect attribute on the WMA file to enable this unit to playback.

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

Compression method	Bit rate	VBR	Sampling frequency
MPEG 1 audio layer 3 (MP3)	32 kj320 kbps	Yes	32, 44.1, 48 kHz
MPEG 2 audio layer 3 (MP3)	8 kj160 kbps	Yes	16, 22.05, 24 kHz

Caution:

≥Never assign the “.mp3”, or “.wma” file name extension to a file that is not in the MP3/WMA format.

This may not only produce noise from the speaker damage, but also damage your hearing.

Windows Medio Audio Ver. 2, Ver. 8 64 kj192 kbps No 32, 44.1, 48 kHz

❐Folder selection order/file playback order (example)

Note:

≥ This unit counts the number of folders irrespective of the

presence or absence of MP3/WMA file.

1Root folder (root directory)

≥ If the selected folder does not contain any MP3/WMA

files, the nearest MP3/WMA files in the order of playback

will be played.
