The ID3 tag is the part of the encoded MP3 or WMA file that contains information about the digital music file such 

as song title, artist, album title, encoding bitrate, track time duration, and so on. ID3 tag information is displayed 

on the Album/Artist/Track title line on the player’s LCD.

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 Fraun-

hofer Institute for Integrated Circuits and Thomson Multimedia. 

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

pressed 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 your Rio Cali 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 

Variable Bitrate (VBR) encoding converts tracks at a variable rate, using higher bitrate encoding for complex por-

tions and lower bitrate encoding for pauses in songs.

Windows Media Audio (WMA) is a compressed audio format created by Microsoft as an alternative to MP3. The 

WMA codec offers greater file compression than the MP3 codec, enabling storage of more digital audio tracks in the 

same amount of space when compared to MP3s at the same level of quality.
