MP3 is the abbreviation of “MPEG-1 Audio
Layer 3”. MPEG is an abbreviation of “Mo-tion Picture Experts Group”, and this is a vid-
eo 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 be- yond the auditory resolution of the human ear
and that are hidden by louder sounds, thus
creating high-quality data with a lower data
size.
This can compress CD audio to approximate- ly 1/10 its original data size without percepti-
ble loss, approximately 10 CDs can be writ-
ten to a single CD-R/RW disc.
