Generally audio CD music sampling rate is _____ and bit depth is _____.;Outcome;Fill in the tutorial summary sheet as best you can, including the group's assessment of how well each person has worked in the group. Hand in to your tutor/lecturer an outcome sheet with the self and peer assessment marks agreed to by the group for each person.;Reflection;It was once common to purchase CDs and other physical storage media to obtain recorded music. What are the advantages and disadvantages of purely electronic distribution? How might the disadvantages be overcome?
