Exam-style question
Try this first
A one-second sound is sampled at 4,000 samples per second using a sample resolution of 8 bits. How many bytes are needed?.
- A.500 bytes
- B.4,000 bytes
- C.8,000 bytes
- D.32,000 bytes
Model answer
What a good answer should say
- 4,000 bytes
Explanation
Why this works
There are 4,000 samples in one second. Each sample uses 8 bits, which is 1 byte, so the total is 4,000 × 1 = 4,000 bytes.
