Explanation:
A 32-second sound clip will be recorded. The sound will be sampled 16000 times a second. Each sample will be stored using 8 bits. Calculate the file size in kilobytes. You must show all of your working.
Answers
The Audio Size of the 32-second sound clip is given as: = 500 kb
See calculation and explanations below.
What is Audio Size?The term audio size is used to refer to the size of an audio file measured in bytes, or kilobytes, or megabytes depending on it's size.
What is the calculation of the size of the audio file?
Step 1
The formula for calculating the Audio Size is:
= Sampling rate x sample size x time x channel
= 16,000hz x 8bits x 32 x 1 (We assume it is only one channel since the number of channels is not specified)
= 4,096,000 bits
Step 2 - We convert to bytes.
To convert to bytes, we divide our answer in bits by 8; hence
= 4,096,000/8
= 512,000
Step 3 - convert to kilobytes by dividing by 1024
Therefore, answer in kilobytes
= 512,000/1024
= 500 kb
