rates of approximately 1/11 (128 kbps) while retaining

 

 

sound quality equivalent to a music CD.

 

 

 

 

Sampling

A value that indicates the number of times per second

21

frequency

analog signals are sampled for conversion to digital

 

 

signals. The sampling frequency for music CDs is 44.1

 

 

kHz. Normally, the higher the sampling frequency, the

 

 

better the sound quality.
