Open-source browser rhythm game runs four local neural nets on your songs

A developer released Struna, an open-source browser rhythm game that runs four audio models—BeatNet, Basic Pitch, Spleeter's vocal separator and SwiftF0—locally via onnxruntime-web, totaling about 22MB, with no uploads. Their beat, note and pitch outputs shape the levels, and plain DSP serves as a fallback on slow devices. The code is MIT-licensed.
