MP3/WMA

What is MP3?

MP3 is an audio compression method and clas- sified into audio layer 3 of MPEG standards. This audio compression method has penetrated into PC users and become a standard format.

This MP3 features the original audio data com- pression to about 10 percent of its initial size with a high sound quality. This means that about 10 music CDs can be recorded on a CD-R disc or CD-RW disc to allow a long listening time without having to change CDs.

What is WMA?

WMA is the abbreviation of Windows Media Au- dio, an audio file format developed by Microsoft Corporation.

Notes:

•If you play a file with DRM (Digital Rights Man- agement) for WMA remaining ON, no audio is output.
