Useful Facts
What is the relationship between bit rate, sound quality, and storage size?
Generally, higher bit rates provide better sound quality, but require more
storage space for the same length of audio, so you can store fewer songs on the
player.
Lower bit rates enable you to store more songs, but at a lower sound quality.
Note
 If you import a song from a CD to your computer at a low bit rate, you cannot improve
the song's sound quality by selecting a high bit rate when further transferring the song
from the computer to the player.
