The document discusses research Oscar Gibb conducted on existing audio products to inform their own audio documentary project. They analyzed comedic interview show "Contractual Obligation" to understand how to keep listeners engaged without pauses. They also examined a formal Brexit documentary to learn how to appeal to older audiences. Louis Theroux and Ross Kemp documentaries were researched to understand interview styles and using sound effects to build tension. Gibb plans to incorporate constant background sound, full interviews, and building tension with sound in their own production to appeal to younger audiences. Audience research on the BBC Sounds platform will also help tailor the project.
