Recording MP3 files on a CD-R/RWWhat is MP3MP3, short for MPEG Audio Layer-3, is a standard for compressing digital video data adopted for video CDs and similarmedia. It is one of the audio compression schemes covered by MPEG's (Motion Picture Experts Group) digital audio com-pression standards. What it does is reduce the number of bytes in a song without hurting the sound quality by means suchas eliminating big sound waves within the sound range that is imperceptible to the human ear. This compression allowsyou to reduce the contents of a conventional music CD by a factor of around 10. This means that you can record the con-tents of 10 music CDs on a single CD-R or CD-RW. (The figures refer to data recorded on a 650 MB CD-R or CD-RW at afixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz.)Points to remember when recording an MP3 discNote: MP3 encode software and writing software are not supplied to this model.
