What have you learnt about technologies from the process of constructing this product? (Evaluation question 6)

In this version of our thriller opening sequence we have annotated all the technologies we have learned and explored.
I thought that the gun mic was particularly interesting, since you simply point it at the origin of the sound and then you have two sound recordings in the editing process. I learned that if you have a track that is way to quiet and boosting the master isn't 'enough you can start layering the tracks to create a louder volume. Also you may select one of them, the one that has the better sound recorded which is usually the external mic.
