Question

A student is recording a song on her computer. When the recording is finished, she saves a copy on her computer. The student notices that the saved copy is of lower sound quality than the original recording. Which of the following could be a possible explanation for the difference in sound quality?
A. The song was saved using fewer bits per second than the original song.
B. The song was saved using more bits per second than the original song.
C. The song was saved using a lossless compression technique.
D. Some information is lost every time a file is saved from one location on a computer to another location.

Answer 1

Answer:

A. The song was saved using fewer bits per second than the original song.

Explanation:

A song can be recorded on the computer or any device ranging from bit rates 96 kbps to 320 kbps.  

The lesser the bitrates the lesser the quality of the audio and when we increase the bit rates, the quality of the audio recorded gradually increases.

Bitrates of 128 kbps give us a radio like quality whereas when we use bitrates of 320 kbps we get very good or CD-like quality.

According to the scenario, the most appropriate answer is option A.
