Insect sounds is a nature-recording genre focused on capturing the acoustic life of insects—crickets, katydids, cicadas, grasshoppers, beetles, and other arthropods—both as documentary field recordings and as contemplative listening material. It privileges unmanipulated, high-fidelity ambience where the insects’ rhythms, choruses, and timbral details become the "music." While scientific collections and sound archives existed earlier, the genre coalesced as a consumer-facing category during the 1970s–1990s alongside nature-sound albums and the field-recording movement. Releases range from taxonomically organized reference compilations to immersive nocturnal soundscapes that emphasize place, season, and time of day. Aesthetically, insect sounds overlap with ambient, new age, and sound art: long takes, minimal intervention, and a strong sense of space. Technically, it relies on specialized microphones (parabolic dishes, contact mics) and high sample rates to render subtle stridulations and ultrasonics with clarity.

Spoken word is a performance-centered genre where text—poems, monologues, stories, or manifestos—is delivered aloud with musicality in voice rather than through singing. It may be entirely a cappella or accompanied by sparse instrumentation (often jazz combos, ambient textures, or minimal electronics) that frames the cadence and rhetoric of the performer. The emphasis is on language: prosody, pacing, imagery, and argument. Pieces often explore personal narratives, social critique, and political themes, drawing on techniques such as internal rhyme, alliteration, and repetition. While recordings exist, the tradition is fundamentally live, prioritizing immediacy, audience engagement, and oratorical presence.

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.

Animal sounds is a non-music, documentary-focused genre centered on the unaccompanied vocalizations and behaviors of animals—such as birdsong, whale song, insect choruses, amphibian calls, and mammal vocalizations—captured in the field. Rather than emphasizing melody, harmony, or beat, works in this genre present the acoustic ecology of a place and time. Producers often favor minimal processing to preserve scientific, educational, and experiential value, though some releases organize recordings into thematic "soundscapes" (e.g., dawn chorus, coastal rookeries). The genre is commonly used for education, research, relaxation, and as raw material for ambient, electroacoustic, and sound art contexts.
