Audio Discs versus Media Discs

Audio CD

An Audio CD is similar to a music CD you buy online or in a store; it can be played on any standard CD player (such as a CD deck or a portable CD player). Music is stored on Audio CDs as uncompressed (essentially WAV) digital files. When compressed audio files (RealAudio, MP3, etc.) are transferred to an Audio CD, RealOne Player makes temporary uncompressed copies of each song before the CD is burned. This increases the time it takes to create the CD and requires up to 700Mb free hard drive space.

Audio CDs can only confidently be burned onto CD-R media. While some CD players can read CD-RWs not all will. You can use CD-RW with RealOne Player, but you should check with the manufacturer of your home or car CD player before burning CD-RWs.

Media [Data] Disc

A Media Disc  is similar to a CD or DVD  you purchase for installing software on your computer; it is just data/files. Use this feature to backup your media files. Choose RealOne Player compatible files (RealAudio, MP3, etc.) from your local drive(s) and burn them onto a Media CD. Files are copied to the disc just as they are, without conversion or modification.

Media Discs may be created from CD-R or CD-RW media.

MP3 [Data] Disc

An MP3 CD is a specialized data disc. All media files are MP3 formatted files, and like the Media CD, they can be organized into folders. The media files on the MP3 CD can also be accompanied by M3U formatted playlists, used by some MP3 players to play the MP3 files on the disk.  When placed in an MP3 compatible CD or DVD player, they can be played like any Audio CD.

MP3 Discs may be created from CD-R or CD-RW media.
