Believe it or not, this Trust Point video was a robust exercise in terms of effects. Much of the audio was deverberated, boosted, then re-reverberated, to reach the higher quality of the rest of the audio. Many cuts were made to remove the stuttering and awkward pauses, and several morph-cuts were subsequently implemented to retain a natural appearance. Someone's sentence was cut short, so there's also a slight pitch shift to reinforce a more natural sound. Can you guess who?
