Séance reconstructs the ambient soundscape of any place in history. Type a location and year, it generates what that moment actually sounded like. History has books for words and paintings for visuals. Nobody captured sound. Séance fills that gap. It uses ElevenLabs Sound Effects API to generate three layered audio tracks (ambient bed, human activity, environmental texture) in parallel. Gemini extracts historical sensory evidence to ground the prompts in reality. Artifacts are stored in Turbopuffer so repeat queries load instantly from the archive, with audio overflow on Cloudflare R2.
