Additional Descriptions
- MP3 (MPEG AUDIO LAyER-3)
MP3 is one of music file formats that can contain music with stereo sound quality as good as audio which is
a type of MPEG as audio, video compression standards. Compression rate is 1Mb by 1 and thus about 3~
5 minutes are sufficient if recording songs of 3~ 5 min or so. Differently from audio a music file made of
MP3 can contain over 130 songs for popular songs or folk songs and playing also about 10 hours. MP3
clears frequency range for a human being not to discernable and advantage to compact it to 1/12 or so
while maintaining music as sound quality equivalent to CD level.
Example, deriving a song in a music CD while maintaining music as sound quality equivalent to CD
becomes capacity of 50MB or so but if compressing and converting it to a MP3, size of the MP3 reduces to
4~5MB.
