MP3 (MPEG-1 Audio Layer-3)
One of the audio compression methods used by MPEG.
It employs the irreversible compression method, which
achieves a high compression rate by thinning out the data
of hardly audible part to human ears. It is said to be
capable of compressing the data quantity by about 1/11
(128 kbps) while maintaining a similar audio quality to
music CD.
WMA (Windows Media Audio)
An audio compression method developed by Microsoft
Corporation. It employs the irreversible compression
method, which achieves a high compression rate by
thinning out the data of hardly audible part to human ears.
It is said to be capable of compressing the data quantity by
about 1/22 (64 kbps) while maintaining a similar audio
quality to music CD.

Glossary

Sampling frequency
The number of sampling (process for digitalizing analog
signals) per second. In principle, the higher the sampling
rate, the wider the frequency range that can be played
back, and the higher the quantized bit rate, the finer the
sound that can be reproduced.
PCM (Pulse Code Modulation)
A signal that is changed to digital format without
compression. A CD is recorded with 16-bit sound at
44.1 kHz.
Track
A CD can be divided into a number of segments (tracks).
Each division is called a track number.
