What is MP3? 
MP3 is an acronym for MPEG Layer 3, a type of audio data 
compression that can reduce digital sound files by a variable 
12:1 ratio with virtually no loss in quantity. It allows to store 
more music into a little memory.  Little memory means compact 
size, so portable MP3 player comes out. 
MP3 files can be very small and yet retain a high sound quality. 
MP3 files usually have the extension .mp3, and can be 
downloaded from the Internet, or can be legally made for 
personal use from the audio CDs that you purchased. 
Please check if the MP3 file(s) is legal before you start to 
use. 
It is illegal to encode MP3 files for trade or sale unless you 
have the expressed and explicit permission of the copyright 
holder(s).
