MP3 is an abbreviation of “MPEG-1 Audio Layer 3”. MPEG is an abbreviation of “Motion Picture Experts Group”, and this is avideo compression standard used in video CDs, etc. MP3 is one of the audio compression meth-ods contained in the MPEG audio standard, and reduces the quality
of sounds that are
beyond the auditory resolution of the human ear and that are hidden by louder sounds, thus creating high-qua
lity data with a lower data
size. Because this can co
mpress CD audio to
approximately 1/10 its orig
inal data size with-
out perceptible loss, approximately 10 CDs can be written to a single CD-R/RW disc. Specifications for MP3 files that can be played are as below.
