Question 12 • Introduction to Information Technology - EL3701

You have a digital audio recording of orchestra music. The bit rate used to create the digital audio recording is 176,400 Hz. What does this mean?

Answer
A
There were 176,400 samples of the orchestra music taken per cycle.
B
The maximum audible frequency for the orchestra recording is 176,400 Hz.
C
The loudness of the orchestra music is beyond the threshold of pain.
D
There were 176,400 samples of the orchestra music taken every second.

Explanation

A sampling rate measured in hertz tells how many audio samples are taken each second. Therefore, 176,400 Hz means 176,400 samples of the orchestra music were taken every second. It does not describe the recording’s maximum audible frequency or loudness.
