Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you increase the bit depth of an audio file then you increase the quality?
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Higher bit depths mean higher resolution audio; if the bit depth is too low, some information of the original audio signal will be lost. With a higher audio bit depth-and therefore a higher resolution-more amplitude values are available for us to record.

Detailed explanation-2: -The higher the bit depth, the more data will be captured to more accurately re-create the sound. If the bit depth is too low, information will be lost, and the reproduced sample will be degraded.

Detailed explanation-3: -A higher bitrate generally means better audio quality. “Bitrate is going to determine audio fidelity, ‘’ says producer and engineer Gus Berry. “You could have the greatest-sounding recording of all time, but if you played it with a low bitrate, it would sound worse on the other end.”

Detailed explanation-4: -As the bit rate increases the amount of data streamed per second increases at a good sampling rate to produce the replica of analog signal with more bit depth(16 for audio) thus increasing the bandwidth and file size to produce the best audio quality.
