Notes on MP3/WMA

What is MP3/WMA?

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 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.
