What is MP3?
MP3, whose official name is “MPEG-1 Audio Layer 3,” is a
compression standard prescribed by the ISO, the International
Standardization Organization and MPEG which is a joint
activity institution of the IEC.
MP3 files contain compressed audio data. MP3 encoding is
capable of compressing audio data at extremely high ratios,
reducing the size of music files to as much as one-tenth their
original size. This is achieved while still maintaining near CD
quality. The MP3 format realizes such high compression ratios
by eliminating the sounds that are either inaudible to the
human ear or masked by other sounds.
Method for creating MP3 files
Audio data is compressed by using MP3 specified software.
For details on creating MP3 files, refer to the user's manual for
that software.
MP3 files that can be played back by this device have the file
extension “mp3”. Files with no extension cannot be played
back.
