The document discusses using a "Pacman" jingle/sound effect in both a documentary and radio trailer to represent a brand identity. The jingle would be placed during the title sequence in the documentary and at the start or after quotes in the radio trailer to introduce the product and capture listeners' attention. The "Pacman" jingle was chosen as it relates to video games and entertainment, the topic of focus, and is a fun, catchy sound likely to grab audience attention.
