Coding3� is audio compression technology that satisfies the demand
for high sound quality and high compression rates. The ATRAC3
format can compress music content to about 1/10 of their original
size, which contributes to reduction of the media volume. The
available transfer bit rates are 132 kbps, 105 kbps and 66 kbps.

MP3 files
MP3, which stands for MPEG-1 Audio Layer3, a standard for audio
files compression supported by the Motion Picture Experts Group,
an ISO (International Organization for Standardization) working
group, enables compression of audio files to about 1/10 of the data
size of a standard compact disc. Since the MP3 encoding algorithm
is public, there are various encoders/decoders that are compliant
with this standard, including freeware that is available for no charge.
Thus, the MP3 standard is widely used in the computer field.
