Part II:

9. Solve the following: accurate answers are expected!

a. total data storage for a 16 bit recording of 24 minutes duration at 44.1KHz

b. total data storage for a 24 bit recording of 22 minutes duration at 20KHz

c. total duration of a 16 bit recording at 16KHz which occupies 200MB

d. total duration of a 24 bit recording at 44.1KHz which occupies 2GB

10. Download and Read: How to Achieve Depth and Dimension in Recording, Mixing, and Mastering -- Discuss and provide a brief synopsis.

11. Download and Read: Compression - All parts. Discuss and provide a brief synopsis.

12. Phase correction is a requirement of digital audio recording - explain why, and how this can be handled.

13. What is quantization noise?

14. Oversampling, once an avant-garde notion, is now ubiquitous. Explain the different types of oversampling and also explain why the technique is so crucial to audio recording as we know it today.

15. Explain the operation of the 1-bit oversampling converter. Upon what basic notion is it predicated?

16. What kind of digital audio media do you think will dominate in the next 5 to 10 years? Explain your reasoning.

17. How is signal processing helped by the digital domain representation of signals?
