of sound.
Upload an audio file to analyse its audio signal in your browser. The Playground detects generic audio transients (sudden changes in sound) and generates simulated haptic patterns. Preview the patterns alongside playback, then export the event data as JSON. This is a general-purpose audio experiment, not game recognition. It does not identify games or interpret gameplay events.
Simulated preview only. No controller is connected or controlled. All haptic feedback shown here is simulated.
Privacy / local audio analysis
Audio analysis happens locally in your browser. Your audio file is not transmitted to a server. Playback and JSON export also happen locally. The website loads external assets, including Google Fonts; the homepage loads Three.js from jsDelivr. These services make network requests to load those assets, but do not receive your audio file.

A visual model of two-motor feedback. It is not a measurement of any physical controller.
