A
How many samples you take in a second in Hertz
4

Number of bits available for each sample
5
Q
File Size

6
Q
What happens when you increase sample rate?
A
Better quality + closer match to original recording -> because the analogue signal was sampled more often
Increase file size
7
Q
What happens when you increase the bit depth?
A
Better quality and closer match to original recording -> means digital file picks up quieter sounds
Increase file size
