In this lesson, we will revisit the digitisation process, in order to understand how the sampling rate and the sample size affect the size and quality of the representation. We will also use a sound editing program.

Q5.
Assume that you have a digital recording of a sound. The duration is 2 seconds. The sampling rate is 4,000 samples per second. The sample size is 2 bytes per sample. Use this information to compute the number of bytes required to represent this sound. You may need to use a calculator for this task.
