Exam-style question
Try this first
How many bytes are required to store 10 seconds of mono sound sampled at 8,000 samples per second with a sample resolution of 16 bits?.
- A.80,000 bytes
- B.160,000 bytes
- C.640,000 bytes
- D.1,280,000 bytes
Model answer
What a good answer should say
- 160,000 bytes
Explanation
Why this works
The number of samples is 8,000 × 10 = 80,000. Each sample uses 16 bits, which is 2 bytes.
The sample size is therefore 80,000 × 2 = 160,000 bytes.
