Notes on MP3/WMA

English

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 (This figure refers 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).

*MPEG Layer-3 audio coding technology licensed from Fraunhofer IIS and Thomson.

Note:

¡MP3/WMA encoding and CD writing software programs are not supplied with this unit.
