File Size Formula
Which is the formula to calculate the file size of sound, when being sampled onto a computer system...
File Size (b) = Sample Rate + Sample Resolution + Length (Sec)
File Size (b) = Sample Rating x Sample definition x Length (Sec)
File Size (b) = Sample Rate x Sample Resolution x Length (Hours)
File Size (b) = Sample Rate x Sample Resolution x Length (Sec)

Increasing the sample rate means the analogue recording is sampled more often?
True
False
Increasing the sample rate means the analogue recording is sampled less often?
True
False
Increasing the sample resolution means the digital file picks up quieter sounds even if they happening at the same time as louder ones.
This will also result in a sampled sound that is closer to the quality of the original analogue recording.
True
False
Increasing the sample resolution means the file size will be smaller and pick up less high and low sounds.
True
False
Increasing either the sample rate or sample resolution will increase the file size?
True
False
