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)! .
