Question

a typical audio sampling rate is ______ samples per second.
44,100
44
440
4,400

Explanation:

The sampling rate is the number of samples taken per second. In audio, a common standard for CD - quality audio is 44,100 samples per second. This is because the Nyquist - Shannon sampling theorem states that to accurately reproduce a signal (in this case, an audio signal), the sampling rate should be at least twice the highest frequency component of the signal. The highest frequency that humans can typically hear is around 20,000 Hz. So, a sampling rate of 44,100 Hz (samples per second) is used to capture audio accurately.

Answer:

44,100
