A studio is interviewing you to work on a production that would allow you to have your first experience with a feature film. They are "on the fence" about whether they should hire you. The reason for their hesitation can be easily addressed: they do not yet know if you can say what is involved in getting the audio right for an expensive production. Write a 150 word, or longer, explanation of two things one can do to make sure the final film has good sound when played in theaters. Be sure to describe, in detail, how each technology or task will benefit the sound quality.
