MP3 is short for Moving Pictures Experts Group Audio Layer 3. MP3 is the most well known compressed digital 

audio file format. This format allows for near “CD quality” sound, but at a fraction of the size of normal audio files. 

MP3 conversion of an audio track from CD-ROM can reduce the file size by approximately a 12:1 ratio with virtually 

no perceptible loss in quality. MP3 compression removes the redundant and irrelevant parts of a sound signal that 

the human ear doesn't hear. This digital sound encoding and compression process was developed by the 

Fraunhofer Institute for Integrated Circuits and Thomson Multimedia.

A playlist is a custom grouping of tracks that has been saved for later use. Rather than playing every track on the 

player, playlists can be used to play specific tracks in specific orders. Rio Carbon supports .asx, .m3u, and .pls 

formatted playlists. Tracks that are referenced by a playlist must be present on the Rio Carbon. Playlists that are 

transferred to a Rio player by an application other than Rio Music Manager may not function properly on Rio 

players.

The PlaysForSure logo assures that digital audio devices and online music stores have been tested and verified by 

Microsoft to work properly together. When you see the PlaysForSure logo at your favorite online music store you’ll 

know that services you purchase from the store will play for sure on your Rio player.

Rip and encode refers to the process of extracting audio from a music CD (ripping) and encoding it into a 

compressed digital audio format like MP3 or WMA.

Rio Music Manager can automatically (or manually) delete old content, transfer new audio content, and keep the 

content on the Rio Carbon fresh and dynamic. Rio Music Manager must be open for synchronization to occur.

Treble notes occupy the higher portion of the sound spectrum. Increasing the treble value will raise the levels of 

the high sounds in your music files. You can select the amount of treble in your music by selecting various 

 options.
