Answer 1

The sampling rate, (how many samples per second are stored) for a CD is 44.1 kHz

Answer 2

The sampling rate for a CD is 44.1 kHz (Option C).

• The number of samples of audio recorded by a CD is called the sampling rate or a sampling frequency of a CD.
• The minimum required sampling frequency to represent an English speech is 8000 Hz. This sampling frequency is commonly used in telephone communications.
• If the sampling rate gets lower, the audio quality of that audio decreases. A higher sampling rate can provide better quality audio.
