CAVE is an immersive, browser-native audio experience that transforms a simple voice recording into a cinematic descent into sound. The app places users inside a dark, atmospheric 3D cave rendered entirely with HTML, CSS, and JavaScript, complete with layered rock geometry, drifting mist, reflective cavern light, motion-reactive depth, and a glowing central chamber. With a single microphone permission grant per session, users can speak into the cave and hear their voice return as if it has traveled deep through a subterranean chamber, shaped by distant reflections, long reverb tails, spatial depth, and realistic echo behavior. What makes CAVE compelling is that it delivers the full experience with no framework, no backend, and no external dependency chain. It uses the MediaRecorder API for browser-based voice capture and the Web Audio API to construct a richer acoustic simulation using delayed direct sound, filtered wall reflections, stereo spread, and custom cave-style reverb. The result is a polished interactive project that feels more like a digital sound installation than a demo page: visually dramatic, technically self-contained, and instantly accessible from any modern browser.
