- June 2022, Paper 2, Q13.3 (2 marks): A 50-second sound has been recorded at a sample rate of 40 000 Hz. Two bytes have been used to store each sample of the sound. Calculate the file size of the so
- Specimen, Paper 2, Q06.1 (2 marks): Describe why the sound must be converted to a digital format before it can be stored on a computer system. [2 marks]
- Specimen, Paper 2, Q06.2 (4 marks): The sound engineer is using a sampling rate of 2000 Hz and a sample resolution of 4 bits. What is the minimum file size of a 5-second recording? Your answer sho
- Specimen, Paper 2, Q06.3 (1 mark): The sound engineer currently uses a sample resolution of 4 bits which enables a sample to be stored as one of 16 different bit patterns. She wants to increase t
