What is MP3?
MP3 stands for MPEG-1 Audio Layer III. It is not a separate format, but a part of MPEG-1 video encoding format, developed by MPEG group in early 1990's. MPEG-1 Audio Layer III (MP3) is a method to store good quality audio into small files by using psychoacoustics in order to get rid of the data from the audio that most of the humans can't hear.
