Eugene V. Debs: Trade Unionist, Socialist, Revolutionary 1855-1926

Audio documentary is a narrative non‑fiction form created specifically for listening. It blends reportage, interviews, archival tape, field recordings, narration, and montage to present real events, people, and ideas. Unlike audio drama, which stages fiction with actors, audio documentary prioritizes factual storytelling and journalistic ethics while borrowing dramatic structure, pacing, and sound design to deepen engagement. Its craft relies on careful research, on‑location sound, and editorial shaping to build scenes and a clear point of view.

Lecture is a spoken-word audio genre centered on the delivery of information and ideas by a single speaker (or a small panel) to an audience. It prioritizes clarity, structure, and rhetorical craft over musical accompaniment, with production focusing on intelligible voice capture and minimal sonic distraction. As a recorded format, lecture evolved from public oratory and classroom teaching into publishable audio: first on phonograph cylinders and 78 rpm discs, later on LPs, cassettes, CDs, and today via digital streaming, podcasts, and open courseware. Topics span philosophy, science, social theory, religion, psychology, technology, and public policy. A typical lecture has an introduction that frames the thesis, a body that progresses through signposted sections and examples, and a conclusion that synthesizes takeaways—sometimes followed by audience Q&A. Audience ambience, brief applause, or light cues may be present, but music beds are rare or restrained.
